Computer virus
–
A computer virus is a type of malicious software program that, when executed, replicates by reproducing itself or infecting other computer programs by modifying them. Infecting computer programs can include as well, data files, or the sector of the hard drive. When this replication succeeds, the areas are then said to be infected with a computer virus. The term virus is also commonly, but erroneously, used to refer to types of malware. The majority of active malware threats are actually trojan horse programs or computer worms rather than computer viruses, the term computer virus, coined by Fred Cohen in 1985, is a misnomer. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to gain access to their hosts computers and computing resources. Computer viruses currently cause billions of dollars worth of damage each year, due to causing system failure, wasting computer resources, corrupting data, increasing maintenance costs. The work of von Neumann was later published as the Theory of self-reproducing automata, in his essay von Neumann described how a computer program could be designed to reproduce itself. Von Neumanns design for a computer program is considered the worlds first computer virus. In 1972, Veith Risak, directly building on von Neumanns work on self-replication, the article describes a fully functional virus written in assembler programming language for a SIEMENS 4004/35 computer system. In 1980 Jürgen Kraus wrote his diplom thesis Selbstreproduktion bei Programmen at the University of Dortmund, in his work Kraus postulated that computer programs can behave in a way similar to biological viruses. The Creeper virus was first detected on ARPANET, the forerunner of the Internet, Creeper was an experimental self-replicating program written by Bob Thomas at BBN Technologies in 1971. Creeper used the ARPANET to infect DEC PDP-10 computers running the TENEX operating system, Creeper gained access via the ARPANET and copied itself to the remote system where the message, Im the creeper, catch me if you can. The Reaper program was created to delete Creeper, in fiction, the 1973 Michael Crichton sci-fi movie Westworld made an early mention of the concept of a computer virus, being a central plot theme that causes androids to run amok. Alan Oppenheimers character summarizes the problem by stating that. theres a pattern here which suggests an analogy to an infectious disease process. To which the replies are stated, Perhaps there are similarities to disease and. In 1982, a program called Elk Cloner was the first personal computer virus to appear in the wild—that is, outside the single computer or lab where it was created. Written in 1981 by Richard Skrenta while in the grade at Mount Lebanon High School near Pittsburgh, it attached itself to the Apple DOS3.3 operating system

MS-DOS
–
MS-DOS is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. MS-DOS resulted from a request in 1981 by IBM for a system to use in its IBM PC range of personal computers. Microsoft quickly bought the rights to 86-DOS from Seattle Computer Products, IBM licensed and released it in August 1981 as PC DOS1.0 for use in their PCs. During its life, several competing products were released for the x86 platform and it was also the underlying basic operating system on which early versions of Windows ran as a GUI. It is a operating system, and consumes negligible installation space. MS-DOS was a form of 86-DOS – owned by Seattle Computer Products. This first version was shipped in August 1980, Microsoft, which needed an operating system for the IBM Personal Computer hired Tim Paterson in May 1981 and bought 86-DOS1.10 for $75,000 in July of the same year. Microsoft kept the number, but renamed it MS-DOS. They also licensed MS-DOS1. 10/1.14 to IBM, within a year Microsoft licensed MS-DOS to over 70 other companies. It was designed to be an OS that could run on any 8086-family computer, thus, there were many different versions of MS-DOS for different hardware, and there is a major distinction between an IBM-compatible machine and an MS-DOS machine. This design would have worked well for compatibility, if application programs had only used MS-DOS services to perform device I/O, Microsoft omitted multi-user support from MS-DOS because Microsofts Unix-based operating system, Xenix, was fully multi-user. After the breakup of the Bell System, however, AT&T Computer Systems started selling UNIX System V, believing that it could not compete with AT&T in the Unix market, Microsoft abandoned Xenix, and in 1987 transferred ownership of Xenix to the Santa Cruz Operation. On 25 March 2014, Microsoft made the code to SCP MS-DOS1.25, as an April Fools joke in 2015, Microsoft Mobile launched a Windows Phone application called MS-DOS Mobile which was presented as a new mobile operating system and worked similar to MS-DOS. Version 3.1 – Support for Microsoft Networks Version 3.2 – First version to support 3.5 inch,720 kB floppy drives and diskettes. Version 3.21 Version 3.22 – Version 3.25 Version 3.3 – First version to support 3.5 inch,1.44 MB floppy drives and diskettes, Version 3. 3a Version 3.31 – supports FAT16B and larger drives. MS-DOS4.0 and MS-DOS4.1 – A separate branch of development with additional multitasking features and it is unrelated to any later versions, including versions 4.00 and 4.01 listed below MS-DOS4. x – includes a graphical/mouse interface. It had many bugs and compatibility issues. Version 4.00 – First version to support a hard disk partition that is greater than 32 MiB. Version 4.01 – Microsoft rewritten Version 4.00 released under MS-DOS label, First version to introduce volume serial number when formatting hard disks and floppy disks

DOS
–
None of these systems were officially named DOS, and indeed DOS is a general term for disk operating system. MS-DOS dominated the IBM PC compatible market between 1981 and 1995, and Microsoft Windows, still ran on top of it until about 2001, dozens of other operating systems also use the acronym DOS, including DOS/360 from 1966. Others are Apple DOS, Apple ProDOS, Atari DOS, Commodore DOS, TRSDOS, see List of DOS operating systems § Other operating systems. IBM PC DOS and its predecessor, 86-DOS, resembled Digital Researchs CP/M—the dominant disk operating system for 8-bit Intel 8080, DOS instead ran on Intel 8086 16-bit processors. Starting with MS-DOS1.28 and PC DOS2.0 the operating system incorporated various features inspired by Xenix, when IBM introduced the IBM PC, built with the Intel 8088 microprocessor, they needed an operating system. Seeking an 8088-compatible build of CP/M, IBM initially approached Microsoft CEO Bill Gates, IBM was sent to Digital Research, and a meeting was set up. However, the negotiations for the use of CP/M broke down, Digital Research wished to sell CP/M on a royalty basis, while IBM sought a single license. Digital Research founder Gary Kildall refused, and IBM withdrew, Gates in turn approached Seattle Computer Products. There, programmer Tim Paterson had developed a variant of CP/M-80, the system was initially named QDOS, before being made commercially available as 86-DOS. Microsoft purchased 86-DOS, allegedly for $50,000 and this became Microsoft Disk Operating System, MS-DOS, introduced in 1981. Within a year Microsoft licensed MS-DOS to over 70 other companies, Microsoft later required the use of the MS-DOS name, with the exception of the IBM variant. IBM continued to develop their version, PC DOS, for the IBM PC, Digital Research became aware that an operating system similar to CP/M was being sold by IBM, and threatened legal action. IBM responded by offering an agreement, they would give PC consumers a choice of PC DOS or CP/M-86, side-by-side, CP/M cost almost $200 more than PC DOS, and sales were low. CP/M faded, with MS-DOS and PC DOS becoming the operating system for PCs. Microsoft originally sold MS-DOS only to original equipment manufacturers, one major reason for this was that not all early PCs were 100% IBM PC compatible. DOS was structured such that there was a separation between the specific device driver code and the DOS kernel. Microsoft provided an OEM Adaptation Kit which allowed OEMs to customize the device driver code to their particular system, by the early 1990s, most PCs adhered to IBM PC standards so Microsoft began selling MS-DOS in retail with MS-DOS5.0. In the mid-1980s Microsoft developed a version of DOS

Floppy disk
–
Floppy disks are read and written by a floppy disk drive. Floppy disks, initially as 8-inch media and later in 5¼-inch and 3½-inch sizes, were a form of data storage and exchange from the mid-1970s into the mid-2000s. These formats are usually handled by older equipment and these disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation. The term floppy disk appeared in print as early as 1970, in 1976, Shugart Associates introduced the first 5¼-inch FDD. By 1978 there were more than 10 manufacturers producing such FDDs, there were competing floppy disk formats, with hard- and soft-sector versions and encoding schemes such as FM, MFM and GCR. The 5¼-inch format displaced the 8-inch one for most applications, the most common capacity of the 5¼-inch format in DOS-based PCs was 360 kB and in 1984 IBM introduced the 1.2 MB dual-sided floppy disk along with its PC-AT model. IBM started using the 720 kB double-density 3½-inch microfloppy disk on its Convertible laptop computer in 1986 and these disk drives could be added to older PC models. In 1988 IBM introduced a drive for 2.88 MB DSED diskettes in its top-of-the-line PS/2 models, throughout the early 1980s, limitations of the 5¼-inch format became clear. Originally designed to be practical than the 8-inch format, it was itself too large, as the quality of recording media grew. A number of solutions were developed, with drives at 2-, 2½-, 3-, 3½-, the large market share of the 5¼-inch format made it difficult for these new formats to gain significant market share. A variant on the Sony design, introduced in 1982 by a number of manufacturers, was then rapidly adopted. By the end of the 1980s, 5¼-inch disks had been superseded by 3½-inch disks, by the mid-1990s, 5¼-inch drives had virtually disappeared, as the 3½-inch disk became the predominant floppy disk. Floppy disks became ubiquitous during the 1980s and 1990s in their use with computers to distribute software, transfer data. Before hard disks became affordable to the population, floppy disks were often used to store a computers operating system. Most home computers from that period have a primary OS and BASIC stored as ROM, by the early 1990s, the increasing software size meant large packages like Windows or Adobe Photoshop required a dozen disks or more. In 1996, there were a five billion standard floppy disks in use. Then, distribution of packages was gradually replaced by CD-ROMs, DVDs. External USB-based floppy disk drives are available, many modern systems provide firmware support for booting from such drives

Lahore
–
Lahore is the capital city of the Pakistani province of Punjab. It is the second most populous city in Pakistan and the 32nd most populous city in the world, the city is located in the north-eastern end of Pakistans Punjab province, near the border with the Indian state of Punjab. Lahore is ranked as a world city, and is one of Pakistans wealthiest cities with an estimated GDP of $58.14 billion as of 2014. Lahore is the cultural centre of the Punjab region, and is the largest Punjabi city in the world. The city has a history, and was once under the rule of the Hindu Shahis, Ghaznavids, Ghurids. Lahore reached the height of its splendour under the Mughal Empire, the city was contested between the Maratha Empire and Durrani Empire, then became capital of the Sikh Empire, before becoming the capital of the Punjab under British rule. Following the independence of Pakistan in 1947, Lahore became the capital of Pakistans Punjab province, Lahore is one of Pakistans most liberal and cosmopolitan cities. It exerts a strong influence over Pakistan. Lahore is a centre for Pakistans publishing industry, and remains the foremost centre of Pakistans literary scene. The city is also a centre of education in Pakistan. Lahore is also home to Pakistans film industry, Lollywood, and is a centre of Qawwali music. The city is much of Pakistans tourist industry, with major attractions including the old Walled City. Lahore is also home to the UNESCO World Heritage Sites of Lahore Fort, the etymology of Lahore is uncertain, but according to legend the city was once known as Lavapura, in honour of Prince Lava of the Hindu epic poem, the Ramayana. Lahore Fort also contains a vacant Lava temple, dedicated to the founder of the city. Lahore was called by different names throughout history, to date there is no conclusive evidence as to when it was founded. Lahore is described as a Hindu principality in the Rajput accounts, keneksen, the founder of Suryavansha, is believed to have migrated out from the city. The Solanki tribe, belonging to Amukhara Pattan, which included the Bhatti Rajputs of Jaisalmer, Lahore appears as the capital of the Punjab for the first time under Anandapala – the Hindu Shahi king who is referred to as the ruler of –after leaving the earlier capital of Waihind. Few references to Lahore remain from before its capture by Sultan Mahmud of Ghaznavi in the 11th century, the sultan took Lahore after a long siege and battle in which the city was torched and depopulated

Pakistan
–
Pakistan, officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people, in terms of area, it is the 33rd-largest country in the world with an area covering 881,913 square kilometres. It is separated from Tajikistan by Afghanistans narrow Wakhan Corridor in the north, Pakistan is unique among Muslim countries in that it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and it is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic, an ethnic civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. The new constitution stipulated that all laws were to conform to the injunctions of Islam as laid down in the Quran. Pakistan has an economy with a well-integrated agriculture sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and it is ranked among the emerging and growth-leading economies of the world, and is backed by one of the worlds largest and fastest-growing middle classes. The post-independence history of Pakistan has been characterised by periods of military rule, the country continues to face challenging problems such as illiteracy, healthcare, and corruption, but has substantially reduced poverty and terrorism and expanded per capita income. It is also a member of CERN. Pakistan is a signatory to the Kyoto Protocol, the Paris Agreement, the name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pāk meaning pure in Persian and Pashto, the letter i was incorporated to ease pronunciation and form the linguistically correct and meaningful name. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan, the earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab. The Vedic Civilization, characterised by Indo-Aryan culture, laid the foundations of Hinduism, Multan was an important Hindu pilgrimage centre. The Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region. Taxila had one of the earliest universities and centres of education in the world. At its zenith, the Rai Dynasty of Sindh ruled this region, the Pala Dynasty was the last Buddhist empire, which, under Dharampala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered the Indus valley from Sindh to Multan in southern Punjab in 711 AD, the Pakistan governments official chronology identifies this as the time when the foundation of Pakistan was laid

Time (magazine)
–
Time is an American weekly news magazine published in New York City. It was founded in 1923 and for decades was dominated by Henry Luce, a European edition is published in London and also covers the Middle East, Africa and, since 2003, Latin America. An Asian edition is based in Hong Kong, the South Pacific edition, which covers Australia, New Zealand and the Pacific Islands, is based in Sydney, Australia. In December 2008, Time discontinued publishing a Canadian advertiser edition, Time has the worlds largest circulation for a weekly news magazine, and has a readership of 26 million,20 million of which are based in the United States. As of 2012, it had a circulation of 3.3 million making it the eleventh most circulated magazine in the United States reception room circuit, as of 2015, its circulation was 3,036,602. Richard Stengel was the editor from May 2006 to October 2013. Nancy Gibbs has been the editor since October 2013. Time magazine was created in 1923 by Briton Hadden and Henry Luce, the two had previously worked together as chairman and managing editor respectively of the Yale Daily News. They first called the proposed magazine Facts and they wanted to emphasize brevity, so that a busy man could read it in an hour. They changed the name to Time and used the slogan Take Time–Its Brief and it set out to tell the news through people, and for many decades the magazines cover depicted a single person. More recently, Time has incorporated People of the Year issues which grew in popularity over the years, notable mentions of them were Barack Obama, Steve Jobs, Matej Turk, etc. The first issue of Time was published on March 3,1923, featuring Joseph G. Cannon, the retired Speaker of the House of Representatives, on its cover, a facsimile reprint of Issue No. 1, including all of the articles and advertisements contained in the original, was included with copies of the February 28,1938 issue as a commemoration of the magazines 15th anniversary. The cover price was 15¢ On Haddens death in 1929, Luce became the dominant man at Time, the Intimate History of a Publishing Enterprise 1923–1941. In 1929, Roy Larsen was also named a Time Inc. director, J. P. Morgan retained a certain control through two directorates and a share of stocks, both over Time and Fortune. Other shareholders were Brown Brothers W. A. Harriman & Co. the Intimate History of a Changing Enterprise 1957–1983. According to the September 10,1979 issue of The New York Times, after Time magazine began publishing its weekly issues in March 1923, Roy Larsen was able to increase its circulation by utilizing U. S. radio and movie theaters around the world. It often promoted both Time magazine and U. S. political and corporate interests, Larsen next arranged for a 30-minute radio program, The March of Time, to be broadcast over CBS, beginning on March 6,1931

Hard disk drive
–
The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a manner, meaning that individual blocks of data can be stored or retrieved in any order. HDDs are a type of storage, retaining stored data even when powered off. Introduced by IBM in 1956, HDDs became the dominant secondary storage device for computers by the early 1960s. Continuously improved, HDDs have maintained this position into the era of servers. More than 200 companies have produced HDDs historically, though after extensive industry consolidation most current units are manufactured by Seagate, Toshiba, as of 2016, HDD production is growing, although unit shipments and sales revenues are declining. While SSDs have higher cost per bit, SSDs are replacing HDDs where speed, power consumption, small size, the primary characteristics of an HDD are its capacity and performance. Capacity is specified in unit prefixes corresponding to powers of 1000, the two most common form factors for modern HDDs are 3. 5-inch, for desktop computers, and 2. 5-inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as PATA, SATA, Hard disk drives were introduced in 1956, as data storage for an IBM real-time transaction processing computer and were developed for use with general-purpose mainframe and minicomputers. The first IBM drive, the 350 RAMAC in 1956, was approximately the size of two medium-sized refrigerators and stored five million six-bit characters on a stack of 50 disks. In 1962 the IBM350 RAMAC disk storage unit was superseded by the IBM1301 disk storage unit, cylinder-mode read/write operations were supported, and the heads flew about 250 micro-inches above the platter surface. Motion of the head array depended upon a binary system of hydraulic actuators which assured repeatable positioning. The 1301 cabinet was about the size of three home refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes, access time was about a quarter of a second. Also in 1962, IBM introduced the model 1311 disk drive, users could buy additional packs and interchange them as needed, much like reels of magnetic tape. Later models of removable pack drives, from IBM and others, became the norm in most computer installations, non-removable HDDs were called fixed disk drives. Some high-performance HDDs were manufactured with one head per track so that no time was lost physically moving the heads to a track, known as fixed-head or head-per-track disk drives they were very expensive and are no longer in production. In 1973, IBM introduced a new type of HDD code-named Winchester and its primary distinguishing feature was that the disk heads were not withdrawn completely from the stack of disk platters when the drive was powered down. Instead, the heads were allowed to land on an area of the disk surface upon spin-down

Disk partitioning
–
Disk partitioning or disk slicing is the creation of one or more regions on a hard disk or other secondary storage, so that an operating system can manage information in each region separately. Partitioning is typically the first step of preparing a newly manufactured disk, the disk stores the information about the partitions locations and sizes in an area known as the partition table that the operating system reads before any other part of the disk. Each partition then appears in the system as a distinct logical disk that uses part of the actual disk. Partitioning a drive is when you divide the total storage of a drive into different pieces, once a partition is created, it can then be formatted so that it can be used on a computer. Creating more than one partition has the advantages, Separation of the operating system. This allows image backups to be made of only the operating system, having a separate area for operating system virtual memory swapping/paging. Keeping frequently used programs and data near each other, having cache and log files separate from other files. These can change size dynamically and rapidly, potentially making a file system full, use of multi-boot setups, which allow users to have more than one operating system on a single computer. Protecting or isolating files, to make it easier to recover a corrupted file system or operating system installation, If one partition is corrupted, other file systems may not be affected. Raising overall computer performance on systems where smaller file systems are more efficient, short stroking, which aims to minimize performance-eating head repositioning delays by reducing the number of tracks used per HDD. The basic idea is that you make one partition approx, 20–25% of the total size of the drive. This partition is expected to, occupy the outer tracks of the HDD, If you limit capacity with short stroking, the minimum throughput stays much closer to the maximum. This technique, however, is not related to creating multiple partitions, for example, a 1 TB disk may have an access time of 12 ms at 200 IOPS with an average throughput of 100 MB/s. When it is partitioned to 100 GB access time may be decreased to 6 ms at 300 IOPS with a throughput of 200 MB/s. Partitioning for significantly less than the size available when disk space is not needed can reduce the time for diagnostic tools such as checkdisk to run or for full image backups to run. It also prevents disk optimizers from moving all frequently accessed files closer to other on the disk. Files can still be moved closer to other on each partition. This issue does not apply to Solid-state drives as access times on those are neither affected by nor dependent upon relative sector positions, may prevent using the whole disk capacity, because it may break free capacities apart

United Kingdom
–
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, the United Kingdom includes the island of Great Britain, Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state—the Republic of Ireland. The Irish Sea lies between Great Britain and Ireland, with an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants, together, this makes it the fourth-most densely populated country in the European Union. The United Kingdom is a monarchy with a parliamentary system of governance. The monarch is Queen Elizabeth II, who has reigned since 6 February 1952, other major urban areas in the United Kingdom include the regions of Birmingham, Leeds, Glasgow, Liverpool and Manchester. The United Kingdom consists of four countries—England, Scotland, Wales, the last three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff and Belfast, respectively. The relationships among the countries of the UK have changed over time, Wales was annexed by the Kingdom of England under the Laws in Wales Acts 1535 and 1542. A treaty between England and Scotland resulted in 1707 in a unified Kingdom of Great Britain, which merged in 1801 with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain, there are fourteen British Overseas Territories. These are the remnants of the British Empire which, at its height in the 1920s, British influence can be observed in the language, culture and legal systems of many of its former colonies. The United Kingdom is a country and has the worlds fifth-largest economy by nominal GDP. The UK is considered to have an economy and is categorised as very high in the Human Development Index. It was the worlds first industrialised country and the worlds foremost power during the 19th, the UK remains a great power with considerable economic, cultural, military, scientific and political influence internationally. It is a nuclear weapons state and its military expenditure ranks fourth or fifth in the world. The UK has been a permanent member of the United Nations Security Council since its first session in 1946 and it has been a leading member state of the EU and its predecessor, the European Economic Community, since 1973. However, on 23 June 2016, a referendum on the UKs membership of the EU resulted in a decision to leave. The Acts of Union 1800 united the Kingdom of Great Britain, Scotland, Wales and Northern Ireland have devolved self-government

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Rootkit
–
The term rootkit is a concatenation of root and the word kit. The term rootkit has negative connotations through its association with malware, Rootkit installation can be automated, or an attacker can install it once theyve obtained root or Administrator access. Obtaining this access is a result of attack on a system. Once installed, it possible to hide the intrusion as well as to maintain privileged access. The key is the root or administrator access, full control over a system means that existing software can be modified, including software that might otherwise be used to detect or circumvent it. Rootkit detection is difficult because a rootkit may be able to subvert the software that is intended to find it, detection methods include using an alternative and trusted operating system, behavioral-based methods, signature scanning, difference scanning, and memory dump analysis. When dealing with firmware rootkits, removal may require hardware replacement, the term rootkit or root kit originally referred to a maliciously modified set of administrative tools for a Unix-like operating system that granted root access. These first-generation rootkits were trivial to detect by using such as Tripwire that had not been compromised to access the same information. Lane Davis and Steven Dake wrote the earliest known rootkit in 1990 for Sun Microsystems SunOS UNIX operating system, additionally, the compiler would detect attempts to compile a new version of the compiler, and would insert the same exploits into the new compiler. A review of the code for the login command or the updated compiler would not reveal any malicious code. This exploit was equivalent to a rootkit, the first malicious rootkit for the Windows NT operating system appeared in 1999, a trojan called NTRootkit created by Greg Hoglund. It was followed by HackerDefender in 2003, the first rootkit targeting Mac OS X appeared in 2009, while the Stuxnet worm was the first to target programmable logic controllers. In 2005, Sony BMG published CDs with copy protection and digital rights management software called Extended Copy Protection, the software included a music player but silently installed a rootkit which limited the users ability to access the CD. Software engineer Mark Russinovich, who created the rootkit detection tool RootkitRevealer, the ensuing scandal raised the publics awareness of rootkits. To cloak itself, the rootkit hid from the user any file starting with $sys$, soon after Russinovichs report, malware appeared which took advantage of that vulnerability of affected systems. One BBC analyst called it a public relations nightmare, Sony BMG released patches to uninstall the rootkit, but it exposed users to an even more serious vulnerability. The company eventually recalled the CDs, in the United States, a class-action lawsuit was brought against Sony BMG. The taps began sometime near the beginning of August 2004 and were removed in March 2005 without discovering the identity of the perpetrators, the intruders installed a rootkit targeting Ericssons AXE telephone exchange

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

TED (conference)
–
TED is a media organization which posts talks online for free distribution, under the slogan ideas worth spreading. TED was founded in February 1984 as a conference, which has been held annually since 1990. TEDs early emphasis was technology and design, consistent with its Silicon Valley origins, but it has broadened its focus to include talks on many scientific, cultural. The main TED conference is held annually in Vancouver, British Columbia, prior to 2014, the conference was held in Long Beach. TED events are held throughout North America and in Europe and Asia. They address a range of topics within the research and practice of science and culture. The speakers are given a maximum of 18 minutes to present their ideas in the most innovative, TEDs current curator is the British former computer journalist and magazine publisher Chris Anderson. Since June 2006, TED Talks have been offered for free viewing online, under an Attribution-NonCommercial-NoDerivatives Creative Commons license, as of March 2016, over 2,400 TED Talks are freely available on the website. In June 2011, TED Talks combined viewing figure stood at more than 500 million, not all TED Talks are equally popular, however. Those given by academics tend to be watched more online while art, TED was conceived in 1984 by architect and graphic designer Richard Saul Wurman, who observed a convergence of the fields of technology, entertainment, and design. Presentations were given by famous mathematician Benoit Mandelbrot and influential members of the community, like Nicholas Negroponte. The event was unsuccessful, it took six years before the second conference was organized. In 2000, Wurman, looking for a successor at age 65, met with new-media entrepreneur, Andersons UK media company Future bought TED. And in November 2001, Andersons non-profit The Sapling Foundation acquired TED from Future for £6m, in February 2002, Anderson gave a TED Talk in which he explained his vision of the conference and his future role of curator. Wurman left after the 2002 conference, in 2006, attendance cost was $4,400 per person and was by invitation only. The membership model was shifted in January 2007 to a membership fee of $6,000, which includes attendance of the conference, club mailings, networking tools.

Malware
–
Before the term malware was coined by Yisrael Radai in 1990, malicious software was referred to as computer viruses. The first category of malware propagation concerns parasitic software fragments that attach themselves to some existing executable content, the fragment may be machine code that infects some existing application, utility, or system program, or even the code used to boot a computer system. Malware is defined by its malicious intent, acting against the requirements of the computer user and it can take the form of executable code, scripts, active content, and other software. Malware is often disguised as, or embedded in, non-malicious files, as of 2011 the majority of active malware threats were worms or trojans rather than viruses. In law, malware is sometimes known as a computer contaminant, Software such as anti-virus and firewalls are used to protect against activity identified as malicious, and to recover from attacks. Many early infectious programs, including the first Internet Worm, were written as experiments or pranks, today, malware is used by both black hat hackers and governments, to steal personal, financial, or business information. Malware is sometimes used broadly against government or corporate websites to gather guarded information, however, malware is often used against individuals to gain information such as personal identification numbers or details, bank or credit card numbers, and passwords. Left unguarded, personal and networked computers can be at considerable risk against these threats, since the rise of widespread broadband Internet access, malicious software has more frequently been designed for profit. Since 2003, the majority of viruses and worms have been designed to take control of users computers for illicit purposes. Infected zombie computers are used to email spam, to host contraband data such as child pornography. Programs designed to monitor users web browsing, display unsolicited advertisements, spyware programs do not spread like viruses, instead they are generally installed by exploiting security holes. They can also be hidden and packaged together with unrelated user-installed software, ransomware affects an infected computer in some way, and demands payment to reverse the damage. For example, programs such as CryptoLocker encrypt files securely, some malware is used to generate money by click fraud, making it appear that the computer user has clicked an advertising link on a site, generating a payment from the advertiser. It was estimated in 2012 that about 60 to 70% of all active malware used some kind of click fraud, Malware is usually used for criminal purposes, but can be used for sabotage, often without direct benefit to the perpetrators. One example of sabotage was Stuxnet, used to very specific industrial equipment. Such attacks were made on Sony Pictures Entertainment and Saudi Aramco, preliminary results from Symantec published in 2008 suggested that the release rate of malicious code and other unwanted programs may be exceeding that of legitimate software applications. According to F-Secure, As much malware produced in 2007 as in the previous 20 years altogether, malwares most common pathway from criminals to users is through the Internet, primarily by e-mail and the World Wide Web. With the amount of malware currently being distributed, some percentage of computers are currently assumed to be infected, for businesses, especially those that sell mainly over the Internet, this means they need to find a way to operate despite security concerns

Cascade (computer virus)
–
The Cascade virus is a prominent computer virus that was a resident written in assembly, and it was widespread in the 1980s and early 1990s. It infected. COM files and had the effect of making text on the fall down. It was notable for using an algorithm to avoid being detected. However one could see that infected files had their size increased by 1701 or 1704 bytes, in response, IBM developed its own antivirus software. The virus has a number of variants, cascade-17Y4, which is reported to have originated in Yugoslavia is almost identical to the most common 1704 byte variant. One byte has been changed, probably due to a random mutation and this, however, has resulted in a bug in the virus. Another mutated variant is also known - it infects the same file over and over, f-Secure Computer Virus Information Pages, Cascade Video of the Cascade virus in action

Morris worm
–
The Morris worm or Internet worm of November 2,1988 was one of the first computer worms distributed via the Internet. It was the first to gain significant mainstream media attention and it also resulted in the first felony conviction in the US under the 1986 Computer Fraud and Abuse Act. It was written by a student at Cornell University, Robert Tappan Morris. According to its creator, Robert Tappan Morris, the Morris worm was not written to cause damage, the worm was released from MIT in the hope of suggesting that its creator studied there, which Morris did not. It worked by exploiting vulnerabilities in Unix sendmail, finger. This would have the effect as a fork bomb and crash the computer several times. The main body of the worm could only infect DEC VAX machines running 4BSD, a portable C grappling hook component of the worm was used to pull over the main body, and the grappling hook could run on other systems, loading them down and making them peripheral victims. The critical error that transformed the worm from a potentially harmless intellectual exercise into a virulent denial of service attack was in the spreading mechanism, the worm could have determined whether to invade a new computer by asking whether there was already a copy running. But just doing this would have made it easy to kill, everyone could just run a process that would answer yes when asked whether there was already a copy. The defense against this was inspired by Michael Rabins mantra Randomization, to compensate for this possibility, Morris directed the worm to copy itself even if the response is yes 1 out of 7 times. This level of replication proved excessive, and the worm spread rapidly, rabin said that Morris should have tried it on a simulator first. The U. S. Government Accountability Office put the cost of the damage at $100, clifford Stoll, who helped fight the worm, wrote in 1989 I surveyed the network, and found that two thousand computers were infected within fifteen hours. These machines were dead in the water—useless until disinfected, and removing the virus often took two days. The Internet was partitioned for several days, as regional networks disconnected from the NSFNet backbone, the Morris worm prompted DARPA to fund the establishment of the CERT/CC at Carnegie Mellon University to give experts a central point for coordinating responses to network emergencies. Gene Spafford also created the Phage mailing list to coordinate a response to the emergency, Robert Morris was tried and convicted of violating United States Code, Title 18, the Computer Fraud and Abuse Act in United States v Morris. After appeals he was sentenced to three years probation,400 hours of community service, and a fine of $10,050 plus the costs of his supervision, the name was derived from the Great Worms of Tolkien, Scatha and Glaurung. In the visual novel Digital, A Love Story, the Morris worm is portrayed as a story for a large-scale attack on ARPANET. In the epilogue of his book The Cuckoos Egg, Stoll details his efforts battling the Morris Worm

Ping-Pong virus
–
The Ping-Pong virus is a boot sector virus discovered on March 1,1988 at the Politecnico di Torino Turin Polytechnic University in Italy. It was likely the most common and best known boot sector virus until outnumbered by the Stoned virus, computers could be contaminated by an infected diskette, showing up as a 1 KB bad cluster to most disk checking programs. Due to being labelled as bad cluster, MS-DOS will avoid overwriting it and it infects disks on every active drive and will even infect non-bootable partitions on the hard disk. Upon infection, the virus becomes memory resident, the virus would become active if a disk access is made exactly on the half-hour and start to show a small ball bouncing around the screen in both text mode and graphical mode. No serious damage is incurred by the virus except on 286 machines, the cause of this crash is the MOV CS, AX instruction, which only exists on 88 and 86 processors. For this reason, users of machines at risk were advised to save their work and reboot, the original Ping Pong virus only infects floppy disks. Later variants of this such as Ping-Pong. B and Ping-Pong. C also infect the hard disk boot sector as well. While the virus is active, one cannot replace the boot sector—it either prevents writing to it or it immediately re-infects it, Ping-Pong. A is extinct but the hard-disk variants can still appear

Stoned (computer virus)
–
Stoned is the name of a boot sector computer virus created in 1987. It is one of the very first viruses and is thought to have been written by a university student in Wellington, by 1989 it had spread widely in New Zealand and Australia, and variants became very common worldwide in the early 1990s. A computer infected with the original version had a one in eight probability that the screen would declare, a phrase found in infected boot sectors of infected floppy disks and master boot records of infected hard disks, along with the phrase Legalise Marijuana. Later variants produced a range of other messages, the original Your computer is now stoned. Legalise Marijuana was thought to have been written by a university student in Wellington, on higher capacity disks, such as 1.2 MB disks, the original boot sector may overwrite a portion of the directory. On hard disks, the master boot record is moved to cylinder 0, head 0. On floppy disks, the boot sector is moved to cylinder 0, head 1, sector 3. The virus will safely overwrite the boot sector if the directory has no more than 96 files. The PC was typically infected by booting from an infected diskette, computers, at the time, would default to booting from the A, diskette drive if it had a diskette. The virus was spread when a floppy diskette was accessed with an infected computer and that diskette was now, itself, a source for further spread of the virus. Cleaning the computer without cleaning all diskettes left the user susceptible to a repeat infection, the method also furthered the spread of the virus in that borrowed diskettes, if placed into the system, were now able to carry the virus to a new host. The virus image is very easily modified, in particular a person with no knowledge of programming can alter the message displayed, many variants of Stoned circulated, some only with different messages. The virus has the string Bloody, on this date, the Tiananmen Square protests were suppressed by the Peoples Republic of China. The virus has the string The Swedish Disaster, Manitoba has no activation routine and does not store the original boot sector on floppies, Manitoba simply overwrites the original boot sector. 2. 88MB EHD floppies are corrupted by the virus, Manitoba uses 2KB memory while resident. NoInt tries to stop programs from detecting it and this causes read errors if the computer tries to access the partition table. Systems infected with NoInt have a decrease of 2 kB in base memory, a variant of Stoned was called Flame. The early Flame uses 1 kB of DOS memory and it stores the original boot sector or master boot record at cylinder 25, head 1, sector 1 regardless of the media
