New Delhi
–
New Delhi is the capital of India and one of Delhi citys 11 districts. The National Capital Region is a larger entity comprising the entire National Capital Territory along with adjoining districts. The foundation stone of the city was laid by George V and it was designed by British architects, Sir Edwin Lutyens and Sir Herbert Baker. The new capital was inaugurated on 13 February 1931, by Viceroy, New Delhi has been selected as one of the hundred Indian cities to be developed as a smart city under Prime Minister of India Narendra Modis flagship Smart Cities Mission. Calcutta was the capital of India during the British Raj until December 1911, Delhi had served as the political and financial centre of several empires of ancient India and the Delhi Sultanate, most notably of the Mughal Empire from 1649 to 1857. During the early 1900s, a proposal was made to the British administration to shift the capital of the British Indian Empire, as India was officially named, from Calcutta on the east coast, to Delhi. The Government of British India felt that it would be easier to administer India from Delhi in the centre of northern India. The land for building the new city of Delhi was acquired under the Land Acquisition Act 1894. The foundation stone of New Delhi was laid by King George V and Queen Mary at the site of Delhi Durbar of 1911 at Kingsway Camp on 15 December 1911, during their imperial visit. Large parts of New Delhi were planned by Edwin Lutyens, who first visited Delhi in 1912, the contract was given to Sobha Singh. The original plan called for its construction in Tughlaqabad, inside the Tughlaqabad fort, construction really began after World War I and was completed by 1931. The city that was later dubbed Lutyens Delhi was inaugurated in ceremonies beginning on 10 February 1931 by Lord Irwin, Lutyens designed the central administrative area of the city as a testament to Britains imperial aspirations. Soon Lutyens started considering other places, however, it was rejected by the Viceroy when the cost of acquiring the necessary properties was found to be too high. The central axis of New Delhi, which faces east at India Gate, was previously meant to be a north-south axis linking the Viceroys House at one end with Paharganj at the other. During the projects early years, many believed it was a gate from Earth to Heaven itself. Eventually, owing to space constraints and the presence of a number of heritage sites in the North side. A site atop the Raisina Hill, formerly Raisina Village, a Meo village, was chosen for the Rashtrapati Bhawan, then known as the Viceroys House. The reason for this choice was that the hill lay directly opposite the Dinapanah citadel, which was considered the site of Indraprastha

Government of India
–
It is located in New Delhi, the capital of India. There is a bicameral Parliament with the Lok Sabha as a lower house, the judicial branch systematically contains an apex Supreme Court,24 high courts, and several district courts, all inferior to the Supreme Court. Similar to the government, individual state governments each consist of executive, legislative. The legal system as applicable to the federal and individual state governments is based on the English Common, the full name of the country is the Republic of India. No other name appears in the Constitution, and this is the name appears on legal banknotes, in treaties. The Union Government, Central Government or Government of India are often used in an official and unofficial capacity to refer to the Government of India, because the seat of government is in New Delhi, New Delhi is commonly used as a metonym for the Central Government. Legislative branch in India is exercised by the Parliament and a legislature consisting of the Rajya Sabha. The latter is considered the house or the House of the people. The Parliament does not have control and sovereignty, as its laws are subject to judicial review by the Supreme Court of India. However, it does exercise some control over the executive branch, the members of the cabinet, including the prime minister and the Council of Ministers, are either chosen from parliament or elected there to within six months of assuming office. The cabinet as a whole is responsible to the Lok Sabha, the Lok Sabha is a temporary house and can only be dissolved when the party in power loses the support of the majority of the house. Whereas the Rajya Sabha is a permanent house which can never be dissolved though the members of the Rajya Sabha who are elected for a six-year term, the Executive Branch of government is the one that has sole authority and responsibility for the daily administration of the state bureaucracy. The division of power into separate branches of government is central to the idea of the separation of powers. The executive power is vested mainly in the President of India, the President has all constitutional powers and exercises them directly or through officers subordinate to him as per the aforesaid Article 53. The President is to act in accordance with aid and advice tendered by the Prime Minister, the Council of Ministers remains in power during the pleasure of the President. However, in practice, the Council of Ministers must retain the support of the Lok Sabha, if a President were to dismiss the Council of Ministers on his or her own initiative, it might trigger a constitutional crisis. Thus, in practice, the Council of Ministers cannot be dismissed as long as it holds the support of a majority in the Lok Sabha, the President is responsible for making a wide variety of appointments. His/Her work is to facilitate smooth transaction of business in Ministries/ Departments of the Government, the President is de jure the Commander in Chief of the Indian Armed Forces

Information and communications technology
–
The term ICT is also used to refer to the convergence of audio-visual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone network with the network system using a single unified system of cabling, signal distribution. However, ICT has no definition, as the concepts, methods. Skills Framework for the Information Age is one of models for describing and managing competencies for ICT professionals for the 21st century. The money spent on IT worldwide has been most recently estimated as US $3.5 trillion and is growing at 5% per year. The 2014 IT budget of US federal government is nearly $82 billion, IT costs, as a percentage of corporate revenue, have grown 50% since 2002, putting a strain on IT budgets. When looking at current companies IT budgets, 75% are recurrent costs, used to keep the lights on in the IT department, the average IT budget has the following breakdown, 31% personnel costs 29% software costs 26% hardware costs 14% costs of external service providers. The worlds technological capacity to store information grew from 2.6 exabytes in 1986 to 15.8 in 1993, over 54.5 in 2000, and to 295 exabytes in 2007, and some 5 zettabytes in 2014. This is the equivalent to 1.25 stacks of CD-ROM from the earth to the moon in 2007. The worlds technological capacity to compute information with humanly guided general-purpose computers grew from 3.0 × 10^8 MIPS in 1986, the following is a list of OECD countries by share of ICT sector in total value added in 2013. The ICT Development Index ranks and compares the level of ICT use, in 2014 ITU released the latest rankings of the IDI, with Denmark attaining the top spot, followed by South Korea. According to this resolution, the General Assembly related the Summit to the United Nations Millennium Declarations goal of implementing ICT to achieve Millennium Development Goals. It also emphasized a multi-stakeholder approach to achieve goals, using all stakeholders including civil society. To help anchor and expand ICT to every part of the world,2015 is the deadline for achievements of the UN Millennium Development Goals. UNESCO takes a holistic and comprehensive approach to promoting ICT in education, access, inclusion and quality are among the main challenges they can address. The Organizations Intersectral Platform for ICT in education focuses on issues through the joint work of three of its sectors, Communication & Information, Education and Science. In modern society ICT is ever-present, with three billion people having access to the Internet. With approximately 8 out of 10 Internet users owning a smartphone, information and data are increasing by leaps, however, hurdles are still at large

National e-Governance Plan
–
The National e-Governance Plan is an initiative of the Government of India to make all government services available to the citizens of India via electronic media. NeGP was formulated by the Department of Electronics and Information Technology and Department of Administrative Reforms, the Government approved the National e-Governance Plan, consisting of 27 Mission Mode Projects and Tencomponents, on 18 May 2006. The ARC report was submitted to the Government of India on 20 December 2008, the report cited several prior initiatives as sources of inspiration, including references to the Singapore ONE programme. To pursue this goal, the National e-Governance Plan was formulated by the Department of Information Technology, lack of needs analysis, business process re-engineering, interoperability across MMPs, and coping with new technology trends were some of the limitations of the initiative.

Telecommunications network
–
A telecommunications network is a collection of terminal nodes, links are connected so as to enable telecommunication between the terminals. The transmission links connect the nodes together, the nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal. Each terminal in the network usually has an address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space, for example, businesses need a greater telecommunications network if they plan to expand their company. With Internet, computer, and telephone networks, businesses can allocate their resources efficiently and these core types of networks will be discussed below, Computer network, a computer network consists of computers and devices connected to one another. Information can be transferred from one device to the next, for example, an office filled with computers can share files together on each separate device. Computer networks can range from a local area to a wide area network. The difference between the types of networks is the size and these types of computer networks work at certain speeds, also known as broadband. The Internet network connects computers worldwide, Internet network, access to the network allows users to use many resources. Over time the Internet network will replace books and this will enable users to discover information almost instantly and apply concepts to different situations. The Internet can be used for recreational, governmental, educational, businesses in particular use the Internet network for research or to service customers and clients. Telephone network, the network connects people to one another. This network can be used in a variety of ways, many businesses use the telephone network to route calls and/or service their customers. Some businesses use a network on a greater scale through a private branch exchange. It is a system where a specific business focuses on routing and servicing calls for another business, majority of the time, the telephone network is used around the world for recreational purposes. In general, every telecommunications network conceptually consists of three parts, or planes, The data plane carries the networks users traffic, the actual payload, the control plane carries control information. The management plane carries the operations and administration traffic required for network management, the management plane is sometimes considered a part of the control plane. The data network is used throughout the world to connect individuals

Time-division multiple access
–
Time-division multiple access is a channel access method for shared-medium networks. It allows several users to share the same channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other and this allows multiple stations to share the same transmission medium while using only a part of its channel capacity. It is also used extensively in satellite systems, combat-net radio systems, for usage of Dynamic TDMA packet mode communication, see below. TDMA is a type of multiplexing, with the special point that instead of having one transmitter connected to one receiver. GSM, D-AMPS, PDC, iDEN, and PHS are examples of TDMA cellular systems, GSM combines TDMA with Frequency Hopping and wideband transmission to minimize common types of interference. In the GSM system, the synchronization of the phones is achieved by sending timing advance commands from the base station which instructs the mobile phone to transmit earlier. This compensates for the delay resulting from the light speed velocity of radio waves. The mobile phone is not allowed to transmit for its time slot. As the transmission moves into the period, the mobile network adjusts the timing advance to synchronize the transmission. Initial synchronization of a phone requires even more care, before a mobile transmits there is no way to actually know the offset required. For this reason, a time slot has to be dedicated to mobiles attempting to contact the network. The mobile attempts to broadcast at the beginning of the time slot, if the mobile is located next to the base station, there will be no time delay and this will succeed. If, however, the phone is at just less than 35 km from the base station. In that case, the mobile will be instructed to broadcast its messages starting nearly a whole time slot earlier than would be expected otherwise. Finally, if the mobile is beyond the 35 km cell range in GSM, then the RACH will arrive in a time slot. It is this feature, rather than limitations of power, that limits the range of a GSM cell to 35 km when no special extension techniques are used, in G. hn, a master device allocates Contention-Free Transmission Opportunities to other slave devices in the network. Only one device can use a CFTXOP at a time, thus avoiding collisions, flexRay protocol which is also a wired network used for safety-critical communication in modern cars, uses the TDMA method for data transmission control

Satellite Internet access
–
Satellite Internet access is Internet access provided through communications satellites. Following the launch of the first satellite, Sputnik 1, by the Soviet Union in October 1957, the first commercial communications satellite was Telstar 1, built by Bell Labs and launched in July 1962. Clarke in a paper in Wireless World in 1945, the first satellite to successfully reach geostationary orbit was Syncom3, built by Hughes Aircraft for NASA and launched August 19,1963. Following the invention of the Internet and the World Wide Web, a significant enabler of satellite-delivered Internet has been the opening up of the Ka band for satellites. In December 1993, Hughes Aircraft Co. filed with the Federal Communications Commission for a license to launch the first Ka-band satellite, in 1995, the FCC issued a call for more Ka-band satellite applications, attracting applications from 15 companies. Among those were EchoStar, Lockheed Martin, GE-Americom, Motorola and KaStar Satellite, the project was abandoned in 2003. It wasn’t until September 2003 when the first Internet-ready satellite for consumers was launched by Eutelsat, in 2004, with the launch of Anik F2, the first high throughput satellite, a class of next-generation satellites providing improved capacity and bandwidth became operational. Internet access services tied to these satellites are targeted largely to rural residents as an alternative to Internet service via dial-up, companies providing home internet service include ViaSat, through its Exede brand, and EchoStar, through subsidiary HughesNet. With this configuration, the number of remote VSATs that can be connected to the hub is virtually limitless, marketed as the center of the new broadband satellite networks are a new generation of high-powered GEO satellites positioned 35,786 kilometres above the equator, operating in Ka-band mode. This spot beam technology allows satellites to reuse assigned bandwidth multiple times which can enable them to much higher overall capacity than conventional broad beam satellites. The spot beams can also increase performance and consequential capacity by focusing more power, note that moving off the tight footprint of a spotbeam can degrade performance significantly. Also, spotbeams can make impossible the use of significant new technologies including Carrier in Carrier modulation. The term bent-pipe is used to describe the shape of the path between sending and receiving antennas, with the satellite positioned at the point of the bend. Simply put, the role in this network arrangement is to relay signals from the end users terminal to the ISPs gateways. The satellite receives, amplifies, and redirects a carrier on a radio frequency through a signal path called a transponder. The satellite has its own set of antennas to receive signals from Earth. These antennas and transponders are part of the payload, which is designed to receive and transmit signals to. The satellites high-gain receiving antenna passes the data to the transponder which filters, translates and amplifies them

Very-small-aperture terminal
–
A very small aperture terminal is a two-way satellite ground station with a dish antenna that is smaller than 3 meters. The majority of VSAT antennas range from 75 cm to 1.2 m, data rates, in most cases, range from 4 kbit/s up to 16 Mbit/s. VSATs access satellites in orbit to relay data from small remote Earth stations to other terminals or master Earth station hubs. VSATs are used to transmit data, or broadband data. VSATs are also used for transportable, on-the-move or mobile maritime communications, the concept of the geostationary orbit was originated by Russian theorist Konstantin Tsiolkovsky, who wrote articles on space travel around the beginning of the 20th century. Clarkes October 1945 Wireless World article discussed the necessary orbital characteristics for a geostationary orbit, live satellite communication was developed in the 1960s by NASA, which called it Syncom 1-3. It transmitted live coverage of the 1964 Olympics in Japan to viewers in the United States, on April 6,1965, the first commercial satellite was launched into space, Intelsat I, nicknamed Early Bird. The first commercial VSATs were C band receive-only systems by Equatorial Communications using spread spectrum technology, more than 30,00060 cm antenna systems were sold in the early 1980s. Equatorial later developed a C band two-way system using 1 m x 0.5 m antennas, in the early 80s, LINKABIT developed the worlds first Ku-band VSAT for Schlumberger to provide network connectivity for oil field drilling and exploration units. LINKABIT which had part of M/A-COM went on to develop Ku band VSATs for enterprise customers such as Walmart, Holiday Inn, Chrysler. These enterprise terminals made up the vast majority of sites for the next 20 years for two-way data or telephony applications. A large VSAT network, with more than 12,000 sites, was deployed by Spacenet, today, the largest VSAT Ku-band network containing over 100,000 VSATs was deployed by and is operated by Hughes Communications for lottery applications. In 2005, WildBlue started deploying VSAT networks deploying Ka-band, viaSat launched the highest capacity satellite ever, ViaSat-1, in 2011 to expand the WildBlue base under its Exede brand. In 2007, Hughes Communications started deploying Ka band VSAT sites for consumers under its HughesNet brand on the Spaceway 3 satellite, by September 2014, Hughes became the first Satellite Internet Provider to surpass one million active terminals. Some VSAT networks are configured by having several centralized uplink sites connected in a topology with each star connected to each other in a mesh topology. Others configured in only a single-star topology sometimes will have each terminal connected to other as well. Advances in technology have improved the price–performance ratio of fixed satellite service over the past five years. New VSAT systems are coming online using Ka band technology that promise higher data rates for lower costs, FSS systems currently in orbit have a huge capacity with a relatively low price structure

Local area network
–
By contrast, a wide area network, not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business, Ethernet and Wi-Fi are the two most common transmission technologies in use for local area networks. Historical technologies include ARCNET, Token ring, and AppleTalk, the increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A1970 report from the Lawrence Radiation Laboratory detailing the growth of their Octopus network gave an indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s, Cambridge Ring was developed at Cambridge University starting in 1974. Ethernet was developed at Xerox PARC in 1973–1975, and filed as U. S, in 1976, after the system was deployed at PARC, Robert Metcalfe and David Boggs published a seminal paper, Ethernet, Distributed Packet-Switching for Local Computer Networks. ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977 and it had the first commercial installation in December 1977 at Chase Manhattan Bank in New York. The initial driving force for networking was generally to share storage and printers, there was much enthusiasm for the concept and for several years, from about 1983 onward, computer industry pundits would regularly declare the coming year to be, “The year of the LAN”. In practice, the concept was marred by proliferation of incompatible physical layer and network protocol implementations, typically, each vendor would have its own type of network card, cabling, protocol, and network operating system. Netware dominated the personal computer LAN business from early after its introduction in 1983 until the mid-1990s when Microsoft introduced Windows NT Advanced Server, of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. During the same period, Unix workstations were using TCP/IP networking, early LAN cabling had generally been based on various grades of coaxial cable. This led to the development of 10BASE-T and structured cabling which is still the basis of most commercial LANs today, while fiber-optic cabling is common for links between switches, use of fiber to the desktop is rare. Many LANs use wireless technologies that are built into Smartphones, tablet computers, in a wireless local area network, users may move unrestricted in the coverage area. Wireless networks have become popular in residences and small businesses, because of their ease of installation, guests are often offered Internet access via a hotspot service. Network topology describes the layout of interconnections between devices and network segments, at the data link layer and physical layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star. At the higher layers, NetBEUI, IPX/SPX, AppleTalk and others were once common, simple LANs generally consist of cabling and one or more switches. A switch can be connected to a router, cable modem, a LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection. LANs can maintain connections with other LANs via leased lines, leased services, depending on how the connections are established and secured, and the distance involved, such linked LANs may also be classified as a metropolitan area network or a wide area network

Internet
–
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, the primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Although the Internet was widely used by academia since the 1980s, Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the two decades since then, Internet use has grown 100-times, measured for the period of one year, newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The entertainment industry was initially the fastest growing segment on the Internet, the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking. Business-to-business and financial services on the Internet affect supply chains across entire industries, the Internet has no centralized governance in either technological implementation or policies for access and usage, each constituent network sets its own policies. The term Internet, when used to refer to the global system of interconnected Internet Protocol networks, is a proper noun. In common use and the media, it is not capitalized. Some guides specify that the word should be capitalized when used as a noun, the Internet is also often referred to as the Net, as a short form of network. Historically, as early as 1849, the word internetted was used uncapitalized as an adjective, the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are often used interchangeably in everyday speech, however, the World Wide Web or the Web is only one of a large number of Internet services. The Web is a collection of interconnected documents and other web resources, linked by hyperlinks, the term Interweb is a portmanteau of Internet and World Wide Web typically used sarcastically to parody a technically unsavvy user. The ARPANET project led to the development of protocols for internetworking, the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department. In an early sign of growth, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks, early international collaborations on the ARPANET were rare. European developers were concerned with developing the X.25 networks, in December 1974, RFC675, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand for internetworking and later RFCs repeated this use. Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network, in 1982, the Internet Protocol Suite was standardized, which permitted worldwide proliferation of interconnected networks.5 Mbit/s and 45 Mbit/s. Commercial Internet service providers emerged in the late 1980s and early 1990s, the ARPANET was decommissioned in 1990

Infrastructure
–
Infrastructure refers to the fundamental facilities and systems serving a country, city, or area, including the services and facilities necessary for its economy to function. The word was imported from French, where it means subgrade, the word is a combination of the Latin prefix infra, meaning below, and structure. The military use of the term achieved currency in the United States after the formation of NATO in the 1940s and this crisis discussion contributed to an increase in infrastructure asset management and maintenance planning in the US. Public-policy discussions have been hampered by lack of a definition for infrastructure. A1987 US National Research Council panel adopted the public works infrastructure. The OECD also classifies communications as a part of infrastructure, the American Society of Civil Engineers has not defined the term, though issuing a US Infrastructure Report Card every 2-4 years. Hard infrastructure refers to the physical networks necessary for the functioning of an industrial nation. The term critical infrastructure distinguishes those infrastructure elements that, if damaged or destroyed. Similarly, a booking system might be critical infrastructure for an airline. These elements of infrastructure are the focus of efforts in the aftermath of natural disasters. The term infrastructure may be confused with the following overlapping or related concepts, service connections to municipal service and public utility networks would also be considered land improvements, not infrastructure. The term public works includes government-owned and operated infrastructure as well as buildings, such as schools. Public works generally refers to physical assets needed to deliver public services, public services include both infrastructure and services generally provided by government. Infrastructure may be owned and managed by governments or by private companies, generally, most roads, major ports and airports, water distribution systems and sewage networks are publicly owned, whereas most energy and telecommunications networks are privately owned. Publicly owned infrastructure may be paid for taxes, tolls, or metered user fees. Major investment projects are financed by the issuance of long-term bonds. Government owned and operated infrastructure may be developed and operated in the sector or in public-private partnerships. As of 2008 in the United States for example, public spending on infrastructure has varied between 2. 3% and 3. 6% of GDP since 1950, many financial institutions invest in infrastructure

Administrative divisions of India
–
The Administrative divisions of India are Indian subnational administrative units, they compose a nested hierarchy of country subdivisions. Indian states and territories frequently use different local titles for the level of subdivision. The smaller subdivisions exist only in rural areas, in urban areas Urban Local Bodies exist instead of these rural subdivisions. The States have been grouped into six zones having an Advisory Council to develop the habit of cooperative working among these States, zonal Councils were set up vide Part-III of the States Reorganisation Act,1956. The North Eastern States special problems are addressed by another statutory body - The North Eastern Council, India is composed of 29 states and 7 union territories. The union territories are governed by administrators, appointed by the President of India, two of the territories have been given partial statehood, with elected legislatures and executive councils of ministers, but limited powers. The Regions of India are not official administrative divisions and they have no official administrative governmental status. They are purely geographic regions, some correspond to countries, states or provinces. A region may comprise one or more divisions, averaging about three divisions per region, however, the boundaries of the regions and the boundaries of the divisions do not always coincide exactly. So far there has no movement to give the regions official administrative status. If this was to be done, it would require that the boundaries of the regions be slightly modified so that they correspond exactly with their constituent districts. Tehsils, talukas, blocks or mandals, headed by a Tehsildar or Talukdar, the governmental bodies at the Tehsil level are called the panchayat samiti. States use varying names for their sub-districts, detailed information is as follows, The block is often the next level of administrative division after the tehsil. Villages are often the lowest level of subdivisions in India, the governmental bodies at the village level are called Gram Panchayat, of which there were an estimated 256,000 in 2002. Each Gram Panchayat covers a large village or a cluster of villages with a combined population exceeding 500 Gram Sabha. Clusters of villages are sometimes called Hobli or Patti. Certain governmental functions and activities - including clean water availability, rural development, India is composed of 1,714,556 habitations In some states, most villages have a single habitation, in others there is a high ratio of habitations to villages. A metro area usually comprises multiple jurisdictions and municipalities, neighbourhoods, townships, cities, exurbs, suburbs, counties, districts, states, as social, economic and political institutions have changed, metropolitan areas have become key economic and political regions. com

Headquarters
–
Headquarters denotes the location where most, if not all, of the important functions of an organization are coordinated. In the United States, the corporate headquarters represents the entity at the center or the top of a corporation taking full responsibility for managing all business activities, in the UK, the term head office is most commonly used for the HQs of large corporations. The term is also used regarding military organizations, a headquarters is the entity at the top of a corporation that takes full responsibility for the overall success of the corporation, and ensures corporate governance. Many companies have an office at a different address to their corporate office. A headquarters normally includes the leader of business unit and his or her staff as well as all functions to manage the business unit, the head of the business unit is responsible for overall result of the business unit. Military headquarters take many forms depending on the size and nature of the unit or formation they command, typically, they are split into the forward, main and rear components, both within NATO nations, and those following the organization and doctrine of the former Soviet Union. The forward or tactical HQs is a group of staff. The main HQs is less mobile and is involved in both the planning and execution of operations, there are a number of staff assembled here from various staff branches to advise the commander, and to control the various aspects of planning and the conduct of discrete operations. A main HQ for a large formation will have a chief of staff who coordinates the staff effort, the rear or logistic HQs is some distance from the battle or front line in conventional operations. The headquarters of the Catholic Church is Vatican City, the headquarters of the Russian Orthodox Church is in Danilov Monastery, Moscow. The World Council of Churches, including Orthodox Churches, has its headquarters in Geneva, the headquarters of Ecumenical Patriarch of Constantinople is located in Istanbul, Turkey. The headquarters of The Church of Jesus Christ of Latter-day Saints is located in Salt Lake City, Utah, the Anglican Communion Office is in London. In Japanese budō martial arts such as karate, judo, aikido, kendo, there is usually a headquarters for each organization or region. The Japanese word honbu is generally used for that, also outside Japan, sometimes they refer to this headquarters as honbu dojo in which dojo is a facility provided for practicing discipline, the training ground. Sometimes honbu is written as hombu, the way it is pronounced, but according to the Hepburn transcription, weapons and Tactics of the Soviet Army Janes, London,516 pp. Wanner, Herbert Global and regional corporate headquarters in, Kählin, Christian, H.

District collector
–
A District Collector, often abbreviated to Collector, is the foremost Indian Administrative Service officer in charge of revenue collection and administration of a district in India. The Collector is assisted by Deputy Collectors, Assistant Collectors, Sub Collectors, District Administration in India is a legacy of the British Raj. District Collectors were members of the Indian Civil Service, and were charged with supervising general administration in the district, warren Hastings introduced the office of the District Collector in 1772. As District Magistrate, he exercised general supervision over the courts and in particular. The office was meant to achieve the purpose of collecting revenue. The Superintendent of Police, Inspector General of Jails, the Surgeon General, the Divisional Forest Officer, until the later part of the nineteenth century, no native was eligible to become a district collector. But with the introduction of competitive examinations for the Indian Civil Services. The district continued to be the unit of administration after India gained independence in 1947, the role of the District Collector remained largely unchanged, except for separation of most judicial powers to judicial officers of the district. They are appointed by the State government, from among the pool of Indian Administrative Service officers in the state, the members of the IAS are either directly recruited by the Union Public Service Commission or promoted from Provincial Civil Services. A District Magistrate, District Collector, Deputy Commissioner or District Commissioner are transferred from this post by State government, District Collectors are entrusted with a wide range of duties in the jurisdiction of the district. Acts as ex-officio chairman of the District Development Authority in absence of Divisional Commissioner, a District Magistrate/District Collector/Deputy Commissioner/District Commissioner is assisted by some I.

Prime Minister of India
–
The Prime Minister of India is the Head of Government and leader of the executive branch of the Government of India. The Prime Minister is also the adviser to the President of India. He or she can be a member of any of the two houses of Parliament, but has to be the leader of the party, having a majority in the Lok Sabha. The Prime Minister is the member of cabinet in the executive branch of government in a parliamentary system. The Prime Minister selects and can dismiss other members of the cabinet, allocates posts to members within the Government, is the presiding member and chairman of the cabinet. The federal or union cabinet headed by the Prime Minister is appointed by the President of India to assist the latter in the administration of the affairs of the executive, Union cabinet is collectively responsible to the Lok Sabha as per Article 75. The Prime Minister shall always enjoy the confidence of Lok Sabha, India follows a parliamentary system in which the prime minister is the presiding, actual head of the government and chief of the executive branch. In such systems, the head of state or the head of states official representative usually holds a ceremonial position. The Prime Minister shall become a member of parliament within six months of beginning his/her tenure, he/She is expected to work with other central ministers to ensure the passage of bills by the Parliament. There shall be a Council of Ministers with the minister at the head to aid and advise the president who shall, in the exercise of his functions. The Prime Minister shall be appointed by the President and the other Ministers shall be appointed by the President on the advice of the Prime Minister. Like most parliamentary democracies, a Presidents duties are mostly ceremonial as long as the constitution and the rule of law is obeyed by the Union Cabinet, the Prime Minister of India is the head of union government and has the responsibility for executive power. The prime minister leads the functioning and exercise of authority of the government of India. President of India invites a person who is commanding support of majority members of Lok Sabha to form government at the federal level, in practice the prime minister nominates the members of their Council of Ministers to the president. They also work upon to decide a core group of Ministers as in-charge of the important functions, some specific ministries/department are not allocated to anyone in the cabinet but the prime minister himself. Per Article 78 of the constitution, the communication between the union cabinet and the president are through the prime minister. Other wise constitution recognises the prime minister as a member of the cabinet only outside the sphere of union cabinet. Be a member of the Lok Sabha or the Rajya Sabha

Rashtrapati Bhavan
–
The Rashtrapati Bhavan, formerly known as Viceroys House, is the official home of the President of India, located at the Western end of Rajpath in New Delhi, India. In terms of area, it is one of the largest residences of a head of state in the world, the British architect Edwin Landseer Lutyens, a major member of the city-planning process, was given the primary architectural responsibility. The completed Governor-Generals palace turned out similar to the original sketches which Lutyens sent Herbert Baker, from Simla. Lutyens design is grandly classical overall, with colours and details inspired by Indian architecture, Lutyens and Baker who had been assigned to work on Viceroys House and the Secretariats, began on friendly terms. Baker had been assigned to work on the two buildings which were in front of Viceroys House. The original plan was to have Viceroys House on the top of Raisina Hill and it was later decided to build it 400 yards back, and put both buildings on top of the plateau. While Lutyens wanted Viceroys House to be higher, he was forced to move it back from the intended position, after completion, Lutyens argued with Baker, because the view of the front of the building was obscured by the high angle of the road. Lutyens campaigned for its fixing, but was not able to get it to be changed, Lutyens wanted to make a long inclined grade all the way to Viceroys House with retaining walls on either side. While this would give a view of the house further back. In 1916 the Imperial Delhi committee dismissed Lutyenss proposal to alter the gradient, Lutyens thought Baker was more concerned with making money and pleasing the government, rather than making a good architectural design. Lutyens travelled between India and England almost every year for twenty years, to work on construction of Viceroys House in both countries. Lutyens reduced the building from 13,000,000 cubic feet to 8,500,000 cubic feet because of the restrictions of Lord Hardinge. While Hardinge demanded that costs be reduced, he wanted the house to retain a certain amount of ceremonial grandeur. On 26 January 1950, when Rajendra Prasad became the first President of India and occupied this building, it was renamed as Rashtrapati Bhavan – the Presidents House. Consisting of four floors and 340 rooms, with an area of 200,000 square feet. The design process of the mansion was long, complicated and politically charged, Lutyens early designs were all starkly classical and entirely European in style. Various Indian designs were added to the building and these included several circular stone basins on top of the building, as water features are an important part of Indian architecture. It blocks harsh sunlight from the windows and also shields the windows from heavy rain during the monsoon season, on the roofline were several chuttris, which helped to break up the flatness of the roofline not covered by the dome

Parliament of India
–
The Parliament of India is the supreme legislative body of the Republic of India. The Parliament is composed of the President of India and the houses and it is bicameral with two houses, the Rajya Sabha and the Lok Sabha. The President in his role as head of legislature has powers to summon. The president can exercise these powers only upon the advice of the Prime Minister and those elected or nominated to either house of Parliament are referred to as members of parliament. The Parliament meets at Sansad Bhavan in New Delhi, the Sansad Bhavan is located in New Delhi. It was designed by Edwin Lutyens and Herbert Baker, who were responsible for planning, the construction of buildings took six years and the opening ceremony was performed on 18 January 1927 by the then Governor-General of India, Irwin. The construction costs for the building were ₹8.3 million, the parliament is 560 feet in diameter and covers an area of 6 acres. The Central hall consists of the chambers of Lok sabha, Rajya Sabha, surrounding these three chambers is the four storied circular structure providing accommodations for members and houses Parliamentary committees, offices and the Ministry of Parliamentary Affairs. A new Parliament building may replace the existing complex, the new building is being considered on account of the stability concerns regarding the current complex. A committee to suggest alternatives to the current building has been set up by the Ex, the present building, an 85-year-old structure suffers from inadequacy of space to house members and their staff and is thought to suffer from structural issues. The building also needs to be protected because of its heritage tag, the Indian Parliament consists of two houses called the Lok Sabha and the Rajya Sabha with the President of India acting as their head. The President of India, the Head of state is a component of Parliament, the President of India is elected by the members of Parliament of India and the state legislatures and serves for a term of five years. Lok Sabha or the house has 545 members. It has a term of five years, Rajya Sabha or the upper house is a permanent body not subject to dissolution. One third of the members every second year, and are replaced by newly elected members. Each member is elected for a term of six years and its members are indirectly elected by members of legislative bodies of the states. The Rajya Sabha can have a maximum of 250 members and it currently has a sanctioned strength of 245 members, of which 233 are elected from States and Union Territories and 12 are nominated by the President. The number of members from a state depends on its population, the minimum age for a person to become a member of Rajya Sabha is 30 years

Computer-aided design
–
Computer-aided design is the use of computer systems to aid in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD is also used and its use in designing electronic systems is known as electronic design automation, or EDA. In mechanical design it is known as mechanical design automation or computer-aided drafting, however, it involves more than just shapes. CAD may be used to design curves and figures in space, or curves, surfaces. CAD is also used to produce computer animation for special effects in movies, advertising and technical manuals. The modern ubiquity and power of computers means that even perfume bottles, because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics, and discrete differential geometry. The design of models for object shapes, in particular, is occasionally called computer-aided geometric design. Eventually CAD provided the designer with the ability to perform engineering calculations, during this transition, calculations were still performed either by hand or by those individuals who could run computer programs. CAD was a change in the engineering industry, where draftsmen, designers. It did not eliminate departments, as much as it merged departments and empowered draftsman, CAD is just another example of the pervasive effect computers were beginning to have on industry. Current computer-aided design software packages range from 2D vector-based drafting systems to 3D solid, modern CAD packages can also frequently allow rotations in three dimensions, allowing viewing of a designed object from any desired angle, even from the inside looking out. Some CAD software is capable of mathematical modeling, in which case it may be marketed as CAD. CAD technology is used in the design of tools and machinery and in the drafting and design of all types of buildings and it can also be used to design objects. Furthermore, many CAD applications now offer advanced rendering and animation capabilities so engineers can better visualize their product designs, 4D BIM is a type of virtual construction engineering simulation incorporating time or schedule related information for project management. CAD has become an important technology within the scope of computer-aided technologies, with benefits such as lower product development costs. CAD enables designers to layout and develop work on screen, print it out, computer-aided design is one of the many tools used by engineers and designers and is used in many ways depending on the profession of the user and the type of software in question. Document management and revision control using Product Data Management, potential blockage of view corridors and shadow studies are also frequently analyzed through the use of CAD

Geographic information system
–
A geographic information system is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries, in general, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS applications are tools that allow users to create interactive queries, analyze spatial information, edit data in maps, Geographic information science is the science underlying geographic concepts, applications, and systems. GIS is a term that can refer to a number of different technologies, processes. It is attached to operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis, GIS can relate unrelated information by using location as the key index variable. Locations or extents in the Earth space–time may be recorded as dates/times of occurrence, and x, y, and z coordinates representing, longitude, latitude, all Earth-based spatial–temporal location and extent references should be relatable to one another and ultimately to a real physical location or extent. This key characteristic of GIS has begun to open new avenues of scientific inquiry, the first known use of the term geographic information system was by Roger Tomlinson in the year 1968 in his paper A Geographic Information System for Regional Planning. Tomlinson is also acknowledged as the father of GIS, previously, one of the first applications of spatial analysis in epidemiology is the 1832 Rapport sur la marche et les effets du choléra dans Paris et le département de la Seine. The French geographer Charles Picquet represented the 48 districts of the city of Paris by halftone color gradient according to the number of deaths by cholera per 1,000 inhabitants and this was one of the earliest successful uses of a geographic methodology in epidemiology. The early 20th century saw the development of photozincography, which allowed maps to be split into layers, for one layer for vegetation. This work was drawn on glass plates but later plastic film was introduced, with the advantages of being lighter, using less storage space and being less brittle. When all the layers were finished, they were combined into one using a large process camera. Once color printing came in, the idea was also used for creating separate printing plates for each color. Computer hardware development spurred by nuclear weapon research led to general-purpose computer mapping applications by the early 1960s, the year 1960 saw the development of the worlds first true operational GIS in Ottawa, Ontario, Canada by the federal Department of Forestry and Rural Development. A rating classification factor was added to permit analysis. CGIS was an improvement over computer mapping applications as it provided capabilities for overlay, measurement and it supported a national coordinate system that spanned the continent, coded lines as arcs having a true embedded topology and it stored the attribute and locational information in separate files. As a result of this, Tomlinson has become known as the father of GIS, CGIS lasted into the 1990s and built a large digital land resource database in Canada

Biomedical
–
Biomedical research is in general simply known as medical research. It is the research, applied research, or translational research conducted to aid. An important kind of research is clinical research, which is distinguished by the involvement of patients. Other kinds of research include pre-clinical research, for example on animals. Both clinical and pre-clinical research phases exist in the pharmaceutical industrys drug development pipelines, however, only part of the clinical or pre-clinical research is oriented towards a specific pharmaceutical purpose. The need for fundamental and mechanistic understanding, diagnostics, medical devices, the most basic medical research is a rapidly evolving area that owes much to basic biology and is given names such as Human Biosciences by universities. The increased longevity of humans over the past century can be attributed to advances resulting from medical research. New, beneficial tests and treatments are expected as a result of the Human Genome Project, many challenges remain, however, including the appearance of antibiotic resistance and the obesity epidemic. Most of the research in the field is pursued by scientists, however significant contributions are made by other biologists. Medical research, done on humans, has to follow the medical ethics as sanctioned in the Declaration of Helsinki. In all cases, the research ethics has to be respected, areas tackled in the most fundamental parts of medical research include cellular and molecular biology, medical genetics, immunology, neuroscience, and psychology. Since many organisms share an evolutionary history with humans and hence common features and systems. Pre-clinical research covers research that prepares the ground for research with patients. Typically the work requires no ethical approval, is supervised by people with PhDs rather than medical doctors, the pre-clinical stage of pharmaceutical testing is covered at Phases of clinical research#Pre-clinical studies. Clinical research is carried out with patients and it is generally supervised by doctors in a medical setting such as a hospital and requires ethical approval. The clinical phase of testing is covered here Clinical trial. Research funding in many countries derives from research bodies and private organizations which distribute money for equipment, in the United Kingdom, funding bodies such as the Medical Research Council derive their assets from UK tax payers, and distribute this to institutions in a competitive manner. The Wellcome Trust is the UKs largest non-governmental source of funds for research and provides over £600 million per year in grants to scientists

Patent
–
A patent is a set of exclusive rights granted by a sovereign state to an inventor or assignee for a limited period of time in exchange for detailed public disclosure of an invention. An invention is a solution to a technological problem and is a product or a process. Patents are a form of intellectual property, the procedure for granting patents, requirements placed on the patentee, and the extent of the exclusive rights vary widely between countries according to national laws and international agreements. Typically, however, a patent application must include one or more claims that define the invention. A patent may include many claims, each of which defines a specific property right and these claims must meet relevant patentability requirements, such as novelty, usefulness, and non-obviousness. Nevertheless, there are variations on what is patentable subject matter from country to country, the word patent originates from the Latin patere, which means to lay open. More directly, it is a version of the term letters patent. Similar grants included land patents, which were land grants by early state governments in the USA, and printing patents, a precursor of modern copyright. In modern usage, the term patent usually refers to the granted to anyone who invents any new, useful. The additional qualification utility patent is used to distinguish the primary meaning from these other types of patents. Particular species of patents for inventions include biological patents, business method patents, chemical patents, the period of protection was 10 years. These were mostly in the field of glass making, as Venetians emigrated, they sought similar patent protection in their new homes. This led to the diffusion of patent systems to other countries, by the 16th century, the English Crown would habitually abuse the granting of letters patent for monopolies. After public outcry, King James I of England was forced to revoke all existing monopolies, the Statute became the foundation for later developments in patent law in England and elsewhere. Important developments in patent law emerged during the 18th century through a process of judicial interpretation of the law. During the reign of Queen Anne, patent applications were required to supply a complete specification of the principles of operation of the invention for public access. Influenced by the philosophy of John Locke, the granting of patents began to be viewed as a form of property right. The English legal system became the foundation for patent law in countries with a common law heritage, including the United States, New Zealand, in the Thirteen Colonies, inventors could obtain patents through petition to a given colonys legislature

Rural area
–
In general, a rural area or countryside is a geographic area that is located outside towns and cities. Whatever is not urban is considered rural, typical rural areas have a low population density and small settlements. Agricultural areas are rural, though so are others such as forests. Different countries have varying definitions of rural for statistical and administrative purposes, in Canada, the census division has been used to represent regions and census consolidated sub-divisions have been used to represent communities. Intermediate regions have 15 to 49 percent of their living in a rural community. Predominantly urban regions have less than 15 percent of their living in a rural community. Predominantly rural regions are classified as rural metro-adjacent, rural non-metro-adjacent and rural northern, following Ehrensaft, as well, rural northern regions encompass all of the Yukon, Northwest Territories and Nunavut. Statistics Canada defines rural for their population counts and this definition has changed over time. Typically, it has referred to the population living outside settlements of 1,000 or less inhabitants, the current definition states that census rural is the population outside settlements with fewer than 1,000 inhabitants and a population density below 400 people per square kilometre. 84% of the United States inhabitants live in suburban and urban areas, Rural areas occupy the remaining 90 percent. The U. S. Census Bureau, the USDAs Economic Research Service, an urbanized area consists of a central surrounding areas whose population is greater than 50,000. USDA The USDAs Office of Rural Development may define rural by various population thresholds, for example, a metropolitan county is one that contains an urbanized area, or one that has a twenty-five percent commuter rate to an urbanized area regardless of population. In 2014, the USDA updated their rural / non-rural area definitions based on the 2010 Census counts, Rural health definitions can be different for establishing under-served areas or health care accessibility in rural areas of the United States. This became the Goldsmith Modification definition of rural, health care delivery in rural areas of the United States can be challenging. From 2005-2011, the rate of potentially preventable hospitalizations for acute conditions was highest in rural areas, in Brazil, theres different notions of rural area and countryside. Rural areas are any place outside an urban development and its carried by informal usage. Otherwise, countryside are officially defined as all municipalities outside the capitals metropolitan region. Some states as Mato Grosso do Sul doesnt have any metropolitan region, thus all of the state, Rio de Janeiro is singular in Brazil and its de facto a metropolitan state, as circa 70% of its population are located in Greater Rio

Agriculture
–
Agriculture is the cultivation and breeding of animals, plants and fungi for food, fiber, biofuel, medicinal plants and other products used to sustain and enhance human life. Agriculture was the key development in the rise of human civilization. The study of agriculture is known as agricultural science, the history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. Industrial agriculture based on large-scale monoculture farming has become the dominant agricultural methodology, genetically modified organisms are an increasing component of agriculture, although they are banned in several countries. Agricultural food production and water management are increasingly becoming global issues that are fostering debate on a number of fronts, the major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials. Specific foods include cereals, vegetables, fruits, oils, meats, fibers include cotton, wool, hemp, silk and flax. Raw materials include lumber and bamboo, other useful materials are also produced by plants, such as resins, dyes, drugs, perfumes, biofuels and ornamental products such as cut flowers and nursery plants. The word agriculture is a late Middle English adaptation of Latin agricultūra, from ager, field, Agriculture usually refers to human activities, although it is also observed in certain species of ant, termite and ambrosia beetle. To practice agriculture means to use resources to produce commodities which maintain life, including food, fiber, forest products, horticultural crops. This definition includes arable farming or agronomy, and horticulture, all terms for the growing of plants, even then, it is acknowledged that there is a large amount of knowledge transfer and overlap between silviculture and agriculture. In traditional farming, the two are often combined even on small landholdings, leading to the term agroforestry, Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin, wild grains were collected and eaten from at least 105,000 years ago. Pigs were domesticated in Mesopotamia around 15,000 years ago, rice was domesticated in China between 13,500 and 8,200 years ago, followed by mung, soy and azuki beans. Sheep were domesticated in Mesopotamia between 13,000 and 11,000 years ago. From around 11,500 years ago, the eight Neolithic founder crops, emmer and einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas and flax were cultivated in the Levant. Cattle were domesticated from the aurochs in the areas of modern Turkey. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca, llamas, alpacas, sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum was domesticated in the Sahel region of Africa by 7,000 years ago, cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia at an unknown time

Hydrography
–
The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the property, even closely held secrets. National organizations, particularly navies, realized that the collection, systematization and distribution of this gave it great organizational. Thus were born dedicated national hydrographic organizations for the collection, organization, publication and distribution of hydrography incorporated into charts, prior to the establishment of the United Kingdom Hydrographic Office, Royal Navy captains were responsible for the provision of their own charts. In practice this meant that ships often sailed with inadequate information for safe navigation, and that when new areas were surveyed, the Admiralty appointed Alexander Dalrymple as Hydrographer in 1795, with a remit to gather and distribute charts to HM Ships. Within a year existing charts from the two centuries had been collated, and the first catalogue published. The first chart produced under the direction of the Admiralty, was a chart of Quiberon Bay in Brittany, under Captain Thomas Hurd the department received its first professional guidelines and the first catalogues were published and made available to the public and to other nations as well. In 1829, Rear-Admiral Sir Francis Beaufort, as Hydrographer, developed the eponymous Scale, and introduced the first official tide tables in 1833, the word hydrography comes from the Ancient Greek ὕδωρ, water and γράφω, to write. The science of oceanography is, in part, an outgrowth of classical hydrography, in many respects the data are interchangeable, but marine hydrographic data will be particularly directed toward marine navigation and safety of that navigation. Marine resource exploration and exploitation is a significant application of hydrography, hydrographical measurements include the tidal, current and wave information of physical oceanography. Bottom measurements also include collection of the nature of the bottom as it pertains to effective anchoring, unlike oceanography, hydrography will include shore features, natural and manmade, that aid in navigation. Hydrography, mostly for reasons of safety, adopted a number of conventions that have affected its portrayal of the data on nautical charts, the former are the mariners tools to avoid accident. The latter are best representations of the seabed, as in a topographic map, for scientific. Trends in hydrographic practice since c, 2003–2005 have led to a narrowing of this difference, with many more hydrographic offices maintaining best observed databases, and then making navigationally safe products as required. This has been coupled with a preference for multi-use surveys, so that the data collected for nautical charting purposes can also be used for bathymetric portrayal. For instance, if there is an area that can not be reached because it is surrounded by shallow water. The color filled areas that show different ranges of water are not the equivalent of contours on a topographic map since they are often drawn seaward of the actual shallowest depth portrayed. A bathymetric chart does show marine topology accurately, details covering the above limitations can be found in Part 1 of Bowditchs American Practical Navigator

Data center
–
A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls, large data centers are industrial scale operations using as much electricity as a small town. Data centers have their roots in the computer rooms of the early ages of the computing industry. Early computer systems, complex to operate and maintain, required an environment in which to operate. Many cables were necessary to all the components, and methods to accommodate and organize these were devised such as standard racks to mount equipment, raised floors. A single mainframe required a deal of power, and had to be cooled to avoid overheating. Security became important – computers were expensive, and were used for military purposes. Basic design-guidelines for controlling access to the room were therefore devised. During the boom of the industry, and especially during the 1980s, users started to deploy computers everywhere. However, as information technology operations started to grow in complexity, the advent of Unix from the early 1970s led to the subsequent proliferation of freely available Linux-compatible PC operating-systems during the 1990s. These were called servers, as timesharing operating systems like Unix rely heavily on the model to facilitate sharing unique resources between multiple users. The use of the data center, as applied to specially designed computer rooms. The boom of data centers came during the bubble of 1997–2000. Companies needed fast Internet connectivity and non-stop operation to deploy systems, installing such equipment was not viable for many smaller companies. Many companies started building very large facilities, called Internet data centers, New technologies and practices were designed to handle the scale and the operational requirements of such large-scale operations. These practices eventually migrated toward the data centers, and were adopted largely because of their practical results. Data centers for cloud computing are called cloud data centers, but nowadays, the division of these terms has almost disappeared and they are being integrated into a term data center. Standards documents from accredited professional groups, such as the Telecommunications Industry Association, well-known operational metrics for data-center availability can serve to evaluate the commercial impact of a disruption

Mathematical model
–
A mathematical model is a description of a system using mathematical concepts and language. The process of developing a model is termed mathematical modeling. Mathematical models are used in the sciences and engineering disciplines. Physicists, engineers, statisticians, operations research analysts, and economists use mathematical models most extensively, a model may help to explain a system and to study the effects of different components, and to make predictions about behaviour. Mathematical models can take many forms, including systems, statistical models, differential equations. These and other types of models can overlap, with a model involving a variety of abstract structures. In general, mathematical models may include logical models, in many cases, the quality of a scientific field depends on how well the mathematical models developed on the theoretical side agree with results of repeatable experiments. Lack of agreement between theoretical mathematical models and experimental measurements often leads to important advances as better theories are developed, in the physical sciences, the traditional mathematical model contains four major elements. These are Governing equations Defining equations Constitutive equations Constraints Mathematical models are composed of relationships. Relationships can be described by operators, such as operators, functions, differential operators. Variables are abstractions of system parameters of interest, that can be quantified, a model is considered to be nonlinear otherwise. The definition of linearity and nonlinearity is dependent on context, for example, in a statistical linear model, it is assumed that a relationship is linear in the parameters, but it may be nonlinear in the predictor variables. Similarly, an equation is said to be linear if it can be written with linear differential operators. In a mathematical programming model, if the functions and constraints are represented entirely by linear equations. If one or more of the functions or constraints are represented with a nonlinear equation. Nonlinearity, even in simple systems, is often associated with phenomena such as chaos. Although there are exceptions, nonlinear systems and models tend to be difficult to study than linear ones. A common approach to nonlinear problems is linearization, but this can be if one is trying to study aspects such as irreversibility

Computer network
–
A computer network or data network is a telecommunications network which allows nodes to share resources. In computer networks, networked computing devices exchange data with other using a data link. The connections between nodes are established using either cable media or wireless media, the best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes, nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Two such devices can be said to be networked together when one device is able to exchange information with the other device, Computer networks differ in the transmission medium used to carry their signals, communications protocols to organize network traffic, the networks size, topology and organizational intent. In most cases, application-specific communications protocols are layered over other more general communications protocols and this formidable collection of information technology requires skilled network management to keep it all running reliably. The chronology of significant computer-network developments includes, In the late 1950s, in 1960, the commercial airline reservation system semi-automatic business research environment went online with two connected mainframes. Licklider developed a group he called the Intergalactic Computer Network. In 1964, researchers at Dartmouth College developed the Dartmouth Time Sharing System for distributed users of computer systems. The same year, at Massachusetts Institute of Technology, a group supported by General Electric and Bell Labs used a computer to route. Throughout the 1960s, Leonard Kleinrock, Paul Baran, and Donald Davies independently developed network systems that used packets to transfer information between computers over a network, in 1965, Thomas Marill and Lawrence G. Roberts created the first wide area network. This was an precursor to the ARPANET, of which Roberts became program manager. Also in 1965, Western Electric introduced the first widely used telephone switch that implemented true computer control, in 1972, commercial services using X.25 were deployed, and later used as an underlying infrastructure for expanding TCP/IP networks. In July 1976, Robert Metcalfe and David Boggs published their paper Ethernet, Distributed Packet Switching for Local Computer Networks, in 1979, Robert Metcalfe pursued making Ethernet an open standard. In 1976, John Murphy of Datapoint Corporation created ARCNET, a network first used to share storage devices. In 1995, the transmission speed capacity for Ethernet increased from 10 Mbit/s to 100 Mbit/s, by 1998, Ethernet supported transmission speeds of a Gigabit. Subsequently, higher speeds of up to 100 Gbit/s were added, the ability of Ethernet to scale easily is a contributing factor to its continued use. Providing access to information on shared storage devices is an important feature of many networks, a network allows sharing of files, data, and other types of information giving authorized users the ability to access information stored on other computers on the network

Training
–
Training is teaching, or developing in oneself or others, any skills and knowledge that relate to specific useful competencies. Training has specific goals of improving ones capability, capacity, productivity and it forms the core of apprenticeships and provides the backbone of content at institutes of technology. People within many professions and occupations may refer to this sort of training as professional development, Physical training concentrates on mechanistic goals, training-programs in this area develop specific skills or muscles, often with a view of peaking at a particular time. Some physical training programs focus on raising overall physical fitness, in military use, training means gaining the physical ability to perform and survive in combat, and learning the many skills needed in a time of war. These include how to use a variety of weapons, outdoor survival skills, while some studies have indicated relaxation training is useful for some medical conditions, autogenic training has limited results or has been the result of few studies. Some commentators use a term for workplace learning to improve performance, training. There are also additional services available online for those who wish to receive training above, some examples of these services include career counseling, skill assessment, and supportive services. One can generally categorize such training as on-the-job or off-the-job, the on-the-job training method takes place in a normal working situation, using the actual tools, equipment, documents or materials that trainees will use when fully trained. On-the-job training has a reputation as most effective for vocational work. It involves employee training at the place of work while he or she is doing the actual job. Usually a professional trainer serves as the course instructor using hands-on training often supported by formal classroom training, sometimes training can occur by using web based technology or video conferencing tools. Simulation based training is another method which uses technology to assist in trainee development and this is particularly common in the training of skills requiring a very high degree of practice, and in those which include a significant responsibility for life and property. An advantage is that simulation training allows the trainer to find, study, off-the-job training method takes place away from normal work situations — implying that the employee does not count as a directly productive worker while such training takes place. Off-the-job training method also involves employee training at an away from the actual work environment. It often utilizes lectures, case studies, role playing and simulation, having the advantage of allowing people to get away from work and this type of training has proven more effective in inculcating concepts and ideas. Many personnel selection companies offer a service which would help to improve employee competences, the internal personnel training topics can vary from effective problem solving skills to leadership training. A more recent development in job training is the On the Job Training Plan, note for example the institutionalised spiritual training of Threefold Training in Buddhism, Meditation in Hinduism or discipleship in Christianity. These aspects of training can be short term or last a lifetime, depending on the context of the training, instructor Guide, is an important document available to an instructor. Specifically, it is used within a Lesson Plan, as the blueprint that ensures instruction is presented in proper sequence, objectives of a lesson plan, To ensure that instructors have considered all factors necessary to conduct a safe and effective lesson

Cybercrime
–
Cybercrime, or computer related crime, is crime that involves a computer and a network. The computer may have used in the commission of a crime. Debarati Halder and K. Cybercrime may threaten a person or a nations security, there are also problems of privacy when confidential information is intercepted or disclosed, lawfully or otherwise. Debarati Halder and K. Internationally, both governmental and non-state actors engage in cybercrimes, including espionage, financial theft, and other cross-border crimes, activity crossing international borders and involving the interests of at least one nation state is sometimes referred to as cyberwarfare. Approximately $1.5 billion was lost in 2012 to online credit and debit card fraud in the US, in 2016, a study by Juniper Research estimated that the costs of cybercrime could be as high as 2.1 trillion by 2019. Computer crime encompasses a range of activities. Computer fraud is any dishonest misrepresentation of fact intended to let another to do or refrain from doing something which causes loss, in this context, the fraud will result in obtaining a benefit by, Altering in an unauthorized way. A variety of scams, many based on phishing and social engineering, target consumers. Government officials and information technology security specialists have documented a significant increase in Internet problems, cyberterrorism in general can be defined as an act of terrorism committed through the use of cyberspace or computer resources. As such, a propaganda piece in the Internet that there will be bomb attacks during the holidays can be considered cyberterrorism. Cyberextortion occurs when a website, e-mail server, or computer system is subjected to or threatened with repeated denial of service or other attacks by malicious hackers and these hackers demand money in return for promising to stop the attacks and to offer protection. More than 20 cases are reported each month to the FBI, perpetrators typically use a distributed denial-of-service attack. An example of cyberextortion was the attack on Sony Pictures of 2014, the U. S. Department of Defense notes that the cyberspace has emerged as a national-level concern through several recent events of geo-strategic significance. Among those are included, the attack on Estonias infrastructure in 2007, in August 2008, Russia again allegedly conducted cyberattacks, this time in a coordinated and synchronized kinetic and non-kinetic campaign against the country of Georgia. Fearing that such attacks may become the norm in future warfare among nation-states and these crimes are committed by a selected group of criminals. Unlike crimes using the computer as a tool, these require the technical knowledge of the perpetrators. As such, as technology evolves, so too does the nature of the crime and these crimes are relatively new, having been in existence for only as long as computers have—which explains how unprepared society and the world in general is towards combating these crimes. These crimes generally involve less technical expertise, the damage dealt is largely psychological and intangible, making legal action against the variants more difficult

Forensic science
–
Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. In addition to their role, forensic scientists testify as expert witnesses in both criminal and civil cases and can work for either the prosecution or the defense. While any field could technically be forensic, certain sections have developed over time to encompass the majority of forensically related cases, the word forensic comes from the Latin term forensis, meaning of or before the forum. The history of the term originates from Roman times, during which a charge meant presenting the case before a group of public individuals in the forum. Both the person accused of the crime and the accuser would give speeches based on their sides of the story, the case would be decided in favor of the individual with the best argument and delivery. This origin is the source of the two usages of the word forensic – as a form of legal evidence and as a category of public presentation. In modern use, the term forensics in the place of science can be considered correct. However, the term is now so closely associated with the field that many dictionaries include the meaning that equates the word forensics with forensic science. The ancient world lacked standardized forensic practices, which aided criminals in escaping punishment, Criminal investigations and trials heavily relied on forced confessions and witness testimony. However, ancient sources do contain several accounts of techniques that foreshadow concepts in science that were developed centuries later. The first written account of using medicine and entomology to solve criminal cases is attributed to the book of Xi Yuan Lu, written in China by Song Ci in 1248, during the Song Dynasty. In one of the accounts, the case of a person murdered with a sickle was solved by an investigator who instructed everyone to bring his sickle to one location, flies, attracted by the smell of blood, eventually gathered on a single sickle. In light of this, the murderer confessed, methods from around the world involved saliva and examination of the mouth and tongue to determine innocence or guilt, as a precursor to the Polygraph test. In ancient India, some suspects were made to fill their mouths with dried rice, similarly, in Ancient China, those accused of a crime would have rice powder placed in their mouths. In ancient middle-eastern cultures, the accused were made to lick hot metal rods briefly, in 16th-century Europe, medical practitioners in army and university settings began to gather information on the cause and manner of death. Ambroise Paré, a French army surgeon, systematically studied the effects of violent death on internal organs, two Italian surgeons, Fortunato Fidelis and Paolo Zacchia, laid the foundation of modern pathology by studying changes that occurred in the structure of the body as the result of disease. In the late 18th century, writings on these began to appear. Two examples of English forensic science in individual legal proceedings demonstrate the use of logic

Computer security
–
A vulnerability is a system susceptibility or flaw. Many vulnerabilities are documented in the Common Vulnerabilities and Exposures database, an exploitable vulnerability is one for which at least one working attack or exploit exists. They may exist for a number of reasons, including by original design or from poor configuration, denial of service attacks are designed to make a machine or network resource unavailable to its intended users. An unauthorized user gaining physical access to a computer is most likely able to copy data from it. They may also compromise security by making operating system modifications, installing software worms, keyloggers, even when the system is protected by standard security measures, these may be able to be by-passed by booting another operating system or tool from a CD-ROM or other bootable media. Disk encryption and Trusted Platform Module are designed to prevent these attacks, eavesdropping is the act of surreptitiously listening to a private conversation, typically between hosts on a network. For instance, programs such as Carnivore and NarusInsight have been used by the FBI, spoofing, in general, is a fraudulent or malicious practice in which communication is sent from an unknown source disguised as a source known to the receiver. Spoofing is most prevalent in communication mechanisms lack a high level of security. Tampering describes a malicious modification of products, so-called Evil Maid attacks and security services planting of surveillance capability into routers are examples. Privilege escalation describes a situation where an attacker with some level of restricted access is able to, without authorization, elevate their privileges or access level. So for example a computer user may be able to fool the system into giving them access to restricted data. Phishing is the attempt to acquire sensitive information such as usernames, passwords, phishing is typically carried out by email spoofing or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Preying on a victims trust, phishing can be classified as a form of social engineering and this is done using multiple transparent or opaque layers. The attacker is basically hijacking the clicks meant for the top level page and routing them to some other irrelevant page, a similar technique can be used to hijack keystrokes. Social engineering aims to convince a user to disclose secrets such as passwords, card numbers, etc. by, for example, impersonating a bank, a common scam involves fake CEO emails sent to accounting and finance departments. In early 2016, the FBI reported that the scam has cost US businesses more than $2bn in about two years, Computer security is critical in almost any industry which uses computers. However, computers can be protected through well built software and hardware, by having strong internal interactions of properties, software complexity can prevent software crash and security failure. In-store payment systems and ATMs have also been tampered with in order to gather customer account data, computers control functions at many utilities, including coordination of telecommunications, the power grid, nuclear power plants, and valve opening and closing in water and gas networks

Videotelephony
–
Videotelephony comprises the technologies for the reception and transmission of audio-video signals by users at different locations, for communication between people in real-time. A videophone is a telephone with a display, capable of simultaneous video. Videoconferencing implies the use of technology for a group or organizational meeting rather than for individuals. Telepresence may refer either to a high-quality videotelephony system or to meetup technology which goes beyond video into robotics, Videoconferencing has also been called visual collaboration and is a type of groupware. It is also used in commercial and corporate settings to facilitate meetings and conferences, Simple analog videophone communication could be established as early as the invention of the television. Such an antecedent usually consisted of two closed-circuit television systems connected via cable or radio. An example of that was the German Reich Postzentralamt video telephone network serving Berlin, the development of the crucial video technology first started in the latter half of the 1920s in the United Kingdom and the United States, spurred notably by John Logie Baird and AT&Ts Bell Labs. This occurred in part, at least with AT&T, to serve as an adjunct supplementing the use of the telephone, a number of organizations believed that videotelephony would be superior to plain voice communications. However video technology was to be deployed in analog television broadcasting long before it could become practical—or popular—for videophones, during the first manned space flights, NASA used two radio-frequency video links, one in each direction. TV channels routinely use this type of videotelephony when reporting from distant locations, the news media were to become regular users of mobile links to satellites using specially equipped trucks, and much later via special satellite videophones in a briefcase. This technique was very expensive, though, and could not be used for such as telemedicine, distance education. Videotelephony developed in parallel with conventional voice telephone systems from the mid-to-late 20th century, Only in the late 20th century with the advent of powerful video codecs combined with high-speed Internet broadband and ISDN service did videotelephony become a practical technology for regular use. In the 1980s, digital telephony transmission networks became possible, such as with ISDN networks, assuring a bit rate for compressed video. During this time, there was research into other forms of digital video. Many of these technologies, such as the Media space, are not as used today as videoconferencing but were still an important area of research. The first dedicated systems started to appear in the market as ISDN networks were expanding throughout the world, one of the first commercial videoconferencing systems sold to companies came from PictureTel Corp. which had an Initial Public Offering in November,1984. The company also secured a patent for a codec for full-motion videoconferencing, in 1992 CU-SeeMe was developed at Cornell by Tim Dorcey et al. In 1995 the first public videoconference between North America and Africa took place, linking a technofair in San Francisco with a techno-rave and cyberdeli in Cape Town
