Humanities are academic disciplines that study aspects of human society and culture. In the Renaissance, the term contrasted with divinity and referred to what is now called classics, the main area of secular study in universities at the time. Today, the humanities are more contrasted with natural, sometimes social, sciences as well as professional training; the humanities use methods that are critical, or speculative, have a significant historical element—as distinguished from the empirical approaches of the natural sciences, unlike the sciences, it has no central discipline. The humanities include ancient and modern languages, philosophy, human geography, politics and art. Scholars in the humanities are humanists; the term "humanist" describes the philosophical position of humanism, which some "antihumanist" scholars in the humanities reject. The Renaissance scholars and artists were called humanists; some secondary schools offer humanities classes consisting of literature, global studies and art.
Human disciplines like history and cultural anthropology study subject matters that the manipulative experimental method does not apply to—and instead use the comparative method and comparative research. Anthropology is a science of the totality of human existence; the discipline deals with the integration of different aspects of the social sciences and human biology. In the twentieth century, academic disciplines have been institutionally divided into three broad domains; the natural sciences seek to derive general laws through verifiable experiments. The humanities study local traditions, through their history, literature and arts, with an emphasis on understanding particular individuals, events, or eras; the social sciences have attempted to develop scientific methods to understand social phenomena in a generalizable way, though with methods distinct from those of the natural sciences. The anthropological social sciences develop nuanced descriptions rather than the general laws derived in physics or chemistry, or they may explain individual cases through more general principles, as in many fields of psychology.
Anthropology does not fit into one of these categories, different branches of anthropology draw on one or more of these domains. Within the United States, anthropology is divided into four sub-fields: archaeology, physical or biological anthropology, anthropological linguistics, cultural anthropology, it is an area, offered at most undergraduate institutions. The word anthropos is from the Greek for "human being" or "person". Eric Wolf described sociocultural anthropology as "the most scientific of the humanities, the most humanistic of the sciences"; the goal of anthropology is to provide a holistic account of human nature. This means that, though anthropologists specialize in only one sub-field, they always keep in mind the biological, linguistic and cultural aspects of any problem. Since anthropology arose as a science in Western societies that were complex and industrial, a major trend within anthropology has been a methodological drive to study peoples in societies with more simple social organization, sometimes called "primitive" in anthropological literature, but without any connotation of "inferior".
Today, anthropologists use terms such as "less complex" societies, or refer to specific modes of subsistence or production, such as "pastoralist" or "forager" or "horticulturalist", to discuss humans living in non-industrial, non-Western cultures, such people or folk remaining of great interest within anthropology. The quest for holism leads most anthropologists to study a people in detail, using biogenetic and linguistic data alongside direct observation of contemporary customs. In the 1990s and 2000s, calls for clarification of what constitutes a culture, of how an observer knows where his or her own culture ends and another begins, other crucial topics in writing anthropology were heard, it is possible to view all human cultures as part of one large. These dynamic relationships, between what can be observed on the ground, as opposed to what can be observed by compiling many local observations remain fundamental in any kind of anthropology, whether cultural, linguistic or archaeological.
Archaeology is the study of human activity through the analysis of material culture. The archaeological record consists of artifacts, biofacts or ecofacts, cultural landscapes. Archaeology can be considered a branch of the humanities, it has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. Archaeology is thought of as a branch of anthropology in the United States, while in Europe, it is viewed as a discipline in its own right, or grouped under other related disciplines such as history. Classics, in the Western academic tradition, refers to the studies of the cultures of classical antiquity, namely Ancient Greek and Latin and the Ancient Greek and Roman cultures. Classical studies is considered one of the cornerstones of the humanities; the influence of classical ideas on many humanities disciplines, such as philosophy and literature, remains strong. History is systematically collected information about the past.
When used as the name of a field of study, history refers to the study and interpretation of the record of humans, societies and any to
Electrical engineering is a professional engineering discipline that deals with the study and application of electricity and electromagnetism. This field first became an identifiable occupation in the half of the 19th century after commercialization of the electric telegraph, the telephone, electric power distribution and use. Subsequently and recording media made electronics part of daily life; the invention of the transistor, the integrated circuit, brought down the cost of electronics to the point they can be used in any household object. Electrical engineering has now divided into a wide range of fields including electronics, digital computers, computer engineering, power engineering, telecommunications, control systems, radio-frequency engineering, signal processing and microelectronics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations such as hardware engineering, power electronics and waves, microwave engineering, electrochemistry, renewable energies, electrical materials science, much more.
See glossary of electrical and electronics engineering. Electrical engineers hold a degree in electrical engineering or electronic engineering. Practising engineers may be members of a professional body; such bodies include the Institute of Electrical and Electronics Engineers and the Institution of Engineering and Technology. Electrical engineers work in a wide range of industries and the skills required are variable; these range from basic circuit theory to the management skills required of a project manager. The tools and equipment that an individual engineer may need are variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software. Electricity has been a subject of scientific interest since at least the early 17th century. William Gilbert was a prominent early electrical scientist, was the first to draw a clear distinction between magnetism and static electricity, he is credited with establishing the term "electricity". He designed the versorium: a device that detects the presence of statically charged objects.
In 1762 Swedish professor Johan Carl Wilcke invented a device named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Hans Christian Ørsted who discovered in 1820 that an electric current produces a magnetic field that will deflect a compass needle, of William Sturgeon who, in 1825 invented the electromagnet, of Joseph Henry and Edward Davy who invented the electrical relay in 1835, of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday, of James Clerk Maxwell, who in 1873 published a unified theory of electricity and magnetism in his treatise Electricity and Magnetism. In 1782 Georges-Louis Le Sage developed and presented in Berlin the world's first form of electric telegraphy, using 24 different wires, one for each letter of the alphabet.
This telegraph connected two rooms. It was an electrostatic telegraph. In 1795, Francisco Salva Campillo proposed an electrostatic telegraph system. Between 1803-1804, he worked on electrical telegraphy and in 1804, he presented his report at the Royal Academy of Natural Sciences and Arts of Barcelona. Salva’s electrolyte telegraph system was innovative though it was influenced by and based upon two new discoveries made in Europe in 1800 – Alessandro Volta’s electric battery for generating an electric current and William Nicholson and Anthony Carlyle’s electrolysis of water. Electrical telegraphy may be considered the first example of electrical engineering. Electrical engineering became a profession in the 19th century. Practitioners had created a global electric telegraph network and the first professional electrical engineering institutions were founded in the UK and USA to support the new discipline. Francis Ronalds created an electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity.
Over 50 years he joined the new Society of Telegraph Engineers where he was regarded by other members as the first of their cohort. By the end of the 19th century, the world had been forever changed by the rapid communication made possible by the engineering development of land-lines, submarine cables, from about 1890, wireless telegraphy. Practical applications and advances in such fields created an increasing need for standardised units of measure, they led to the international standardization of the units volt, coulomb, ohm and henry. This was achieved at an international conference in Chicago in 1893; the publication of these standards formed the basis of future advances in standardisation in various industries, in many countries, the definitions were recognized in relevant legislation. During these years, the study of electricity was considered to be a subfield of physics since the early electrical technology was considered electromechanical in nature; the Technische Universität Darmstadt founded the world's first department of electrical engineering in 1882.
The first electrical engineering degree program was started at Massachusetts Institute of Technology in the physics department
Sheikh ul-Alam International Airport
Sheikh ul-Alam International Airport known as Srinagar Airport is an international airport that serves Srinagar, the summer capital of Jammu and Kashmir. It is owned by the Indian Air Force, the Airports Authority of India operates a civil enclave at the airport. Although, designated an international airport in 2005, the Srinagar airport does not receive scheduled international flights as of September 2018 but has seen Hajj Flights, it has one asphalt runway. The airport has taxi service to the city of Srinagar, which lies 12 kilometres to the north; the airport resides in Budgam, just 4 km from Srinagar. The Srinagar airport was used only by the Indian Air Force. During the Indo-Pakistani War of 1947, the airport received an airlift of Indian troops who prevented Pakistan from capturing the city of Srinagar. Although the airport was small and lacked landing aids, the airlift was still carried out on 27 October. In September 1965, the Srinagar airport was subjected to an air raid amid the Indo-Pakistani War of 1965, which left some aircraft damaged.
In 1979, the Airports Authority of India established a civil enclave at the airport. The terminal was modified in February 1998 to be able to handle international Hajj flights, which first started operating from Srinagar in January 2002. During the Kargil War in 1999, the airport was taken over by the Air Force, civilian flights were prohibited from landing. In March 2005, the airport was granted international status by the Indian government. In 2006 the airport was renamed Sheikh-ul-Alam International Airport after the Kashmiri patron saint. An expanded terminal, able to serve both domestic and international flights, was inaugurated on 14 February 2009 by politician Sonia Gandhi, it was part of a larger expansion project that included an increase in the number of parking stands from four to nine. The total cost of the project was ₹130 crore provided by the Indian government. On the same day, Air India Express started once weekly flights to Dubai, the first scheduled international flights from Srinagar.
However, due to low demand from passengers, the flights were terminated in January 2010. The authorities are planning to create a new airport terminal handling International flights as of 2019; the Srinagar airport has an integrated terminal, handling both domestic and international flights, it can handle aircraft such as Boeing 747-8 and Airbus A380. It covers 19,700 square metres and can serve 950 passengers at a time: 500 domestic and 450 international passengers; the terminal is designed to look like the Himalayas and has a sloping roof that facilitates snow removal. Amenities include a restaurant, a handicrafts shop, ATMs, currency exchange, chocolates shop, free WiFi. There is 13/31, with dimensions 3,685 by 46 metres, it has been equipped to handle instrument landing system approaches since February 2011. Several food joints like KFC and Pizza Hut are available in the airport since 2018. In December 2017, it was announced. In August 2018, a test flight was conducted by DGCA Team and it was passed.
As of Feb 2019, the airport does not handle any night operations. On 7 September 1965, amid the Indo-Pakistani War of 1965, four fighter jets of the Pakistan Air Force attacked the Srinagar airport. An Indian Air Force Douglas C-47 Skytrain and an Indian Airlines Douglas DC-3 were destroyed during the air raid. A Chicago Tribune article published the following day reported that one Indian aircraft and a "Caribou transport of the United Nations observers headquarters" were damaged; the airport is located about 12 kilometres from the city of Srinagar. There is a car park with 250 spaces; the government provides a paid bus service between the airport and the Tourist Resource Centre near Lal Chowk, while the Airports Authority of India operates a free bus service between the terminal and the airport entrance gate 1 kilometre away. The airport is served by taxis and car rental agencies, which have their booths outside the terminal.

Mechanical engineering is the discipline that applies engineering, engineering mathematics, materials science principles to design, analyze and maintain mechanical systems. It is one of the broadest of the engineering disciplines; the mechanical engineering field requires an understanding of core areas including mechanics, thermodynamics, materials science, structural analysis, electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design, computer-aided manufacturing, product life cycle management to design and analyze manufacturing plants, industrial equipment and machinery and cooling systems, transport systems, watercraft, medical devices and others, it is the branch of engineering that involves the design and operation of machinery. Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century. In the 19th century, developments in physics led to the development of mechanical engineering science.
The field has continually evolved to incorporate advancements. It overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, other engineering disciplines to varying amounts. Mechanical engineers may work in the field of biomedical engineering with biomechanics, transport phenomena, bionanotechnology, modelling of biological systems; the application of mechanical engineering can be seen in the archives of various ancient and medieval societies. In ancient Greece, the works of Archimedes influenced mechanics in the Western tradition and Heron of Alexandria created the first steam engine. In China, Zhang Heng improved a water clock and invented a seismometer, Ma Jun invented a chariot with differential gears; the medieval Chinese horologist and engineer Su Song incorporated an escapement mechanism into his astronomical clock tower two centuries before escapement devices were found in medieval European clocks.
He invented the world's first known endless power-transmitting chain drive. During the Islamic Golden Age, Muslim inventors made remarkable contributions in the field of mechanical technology. Al-Jazari, one of them, wrote his famous Book of Knowledge of Ingenious Mechanical Devices in 1206 and presented many mechanical designs. Al-Jazari is the first known person to create devices such as the crankshaft and camshaft, which now form the basics of many mechanisms. During the 17th century, important breakthroughs in the foundations of mechanical engineering occurred in England. Sir Isaac Newton formulated Newton's Laws of Motion and developed Calculus, the mathematical basis of physics. Newton was reluctant to publish his works for years, but he was persuaded to do so by his colleagues, such as Sir Edmond Halley, much to the benefit of all mankind. Gottfried Wilhelm Leibniz is credited with creating Calculus during this time period. During the early 19th century industrial revolution, machine tools were developed in England and Scotland.
This allowed mechanical engineering to develop as a separate field within engineering. They brought with them manufacturing machines and the engines to power them; the first British professional society of mechanical engineers was formed in 1847 Institution of Mechanical Engineers, thirty years after the civil engineers formed the first such professional society Institution of Civil Engineers. On the European continent, Johann von Zimmermann founded the first factory for grinding machines in Chemnitz, Germany in 1848. In the United States, the American Society of Mechanical Engineers was formed in 1880, becoming the third such professional engineering society, after the American Society of Civil Engineers and the American Institute of Mining Engineers; the first schools in the United States to offer an engineering education were the United States Military Academy in 1817, an institution now known as Norwich University in 1819, Rensselaer Polytechnic Institute in 1825. Education in mechanical engineering has been based on a strong foundation in mathematics and science.
Degrees in mechanical engineering are offered at various universities worldwide. Mechanical engineering programs take four to five years of study and result in a Bachelor of Engineering, Bachelor of Science, Bachelor of Science Engineering, Bachelor of Technology, Bachelor of Mechanical Engineering, or Bachelor of Applied Science degree, in or with emphasis in mechanical engineering. In Spain and most of South America, where neither B. Sc. nor B. Tech. Programs have been adopted, the formal name for the degree is "Mechanical Engineer", the course work is based on five or six years of training. In Italy the course work is based on five years of education, training, but in order to qualify as an Engineer one has to pass a state exam at the end of the course. In Greece, the coursework is based on a five-year curriculum and the requirement of a'Diploma' Thesis, which upon completion a'Diploma' is awarded rather than a B. Sc. In the United States, most undergraduate mechanical engineering programs are accredited by the Accreditation Board for Engineering and Technology to ensure similar course requirements and standards a
National Institutes of Technology
The National Institutes of Technology are autonomous public institutes of higher education, located in India. They are governed by the National Institutes of Technology Act, 2007, which declared them as institutions of national importance alongside Indian Institutes of Technology; these institutes of national importance receive special recognition from the Government of India. The NIT Council is the supreme governing body of India's National Institutes of Technology system and all 31 NITs are funded by the Government of India; these institutes are among the top ranked engineering colleges in India and have one of the lowest acceptance rates for engineering institutes, of around 2 to 3 percent, second only to the Indian Institutes of Technology in India. All NITs are autonomous; the language of instruction is English at all these institutes. NITs offer degree courses at bachelors and doctorate levels in various branches of engineering, architecture and science. Admission to the under-graduate courses such as Bachelor of Technology and Bachelor of Architecture programs in NITs are through the competitive Joint Entrance Examination.
Admission to postgraduate courses are through the Graduate Aptitude Test in Engineering for Master of Technology and Master of Science programs, Common Admission Test for Master of Business Administration program and NIMCET for Master of Computer Applications program. Since 2015, the Joint Seat Allocation Authority and Centralized Counselling for M. Tech/M. Arch and M. Plan conduct the admission process for undergraduate and postgraduate programs in all NITs; as of 2017, the total number of seats for undergraduate programs is 19,000 and for post graduate programs is 8,050 in all 31 NITs. During the second five-year plan in India, a number of industrial projects were contemplated. To ensure enough supply of trained personnel to meet the demand for these projects, a decision was taken to start the Regional Engineering Colleges, at the rate of one per each major state, which can churn out graduates with good engineering merit. Thus, seventeen RECs were established from 1959 onwards in each of the major states.
Each college was a joint and cooperative enterprise of the central government and the concerned state government. The Government opened 8 RECs in 1960 two in each region, as follows: Later on 5 more were added by 1965; the early 14 Institutes were Srinagar, Calicut, Kurukshetra, Jaipur, Rourkela, Surat, Trichy and Allahabad. It established one in Silchar in 1967 and added two others located at Hamirpur in 1986, Jalandhar in 1987; these were large-sized institutions judged by the standards prevailing in the country. The considerations that weighed in this decision were: A large-sized college would be more efficient than the equivalent small colleges, the proposed colleges have to meet the additional requirements of the country as a whole and for that purpose should have to function on an all-India basis. Therefore, the smaller they are in number and the larger in size, the better, for the same reason their location is important from an all-India point of view; the RECs were jointly operated by the concerned state government.
Non-recurring expenditures and expenditures for post-graduate courses during the REC period were borne by the central government while recurring expenditure on undergraduate courses was shared by central and state governments. The success of technology-based industry led to high demand for scientific education. Due to the enormous costs and infrastructure involved in creating globally respected Indian Institutes of Technology, in 2002 Ministry of Human Resource Development Minister Murli Manohar Joshi decided to upgrade RECs to "National Institutes of Technology" instead of creating IITs; the central government controls provides all funding. In 2002, all RECs became NITs; the upgrade was designed along the lines of the Indian Institutes of Technology after it was concluded that RECs had potential as proven by the success of their alumni and their contributions in the field of technical education. Subsequently and autonomy for NITs increased, they award degrees which have raised their graduates' perceived value.
These changes implemented recommendations of the "High Powered Review Committee". The HPRC, chaired by R. A. Mashelkar, submitted its report entitled "Strategic Road Map for Academic Excellence of Future RECs" in 1998. In 2004, MHRD issued NIT status to three more colleges, located at Patna and Agartala. Based on the request of state governments and feasibility, future NITs are either converted from existing institutes or can be freshly created; the 21st NIT is planned for Imphal in the north-eastern state of Manipur at an initial cost of Rs. 500 crores. In 2010, the government announced setting up ten new NITs in the remaining states/territories; this would lead to every state in India having its own NIT. With the technology based industry's continuing growth, the government decided to upgrade twenty National Institutes of Technology to full-fledged technical universities. Parliament passed enabling legislation, the National Institutes of Technology Act in 2007 and took effect on 15 August of that year.
The target is to fulfill the need for quality manpower in the field of engineering and technology and to provide consistent governance, fee structure, rules across the NITs. The law designates each NIT an Institute of Na
Information technology is the use of computers to store, retrieve and manipulate data, or information in the context of a business or other enterprise. IT is considered to be a subset of communications technology. An information technology system is an information system, a communications system or, more speaking, a computer system – including all hardware and peripheral equipment – operated by a limited group of users. Humans have been storing, retrieving and communicating information since the Sumerians in Mesopotamia developed writing in about 3000 BC, but the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review. We shall call it information technology." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, the simulation of higher-order thinking through computer programs. The term is used as a synonym for computers and computer networks, but it encompasses other information distribution technologies such as television and telephones.
Several products or services within an economy are associated with information technology, including computer hardware, electronics, internet, telecom equipment, e-commerce. Based on the storage and processing technologies employed, it is possible to distinguish four distinct phases of IT development: pre-mechanical, electromechanical, electronic; this article focuses on the most recent period, which began in about 1940. Devices have been used to aid computation for thousands of years initially in the form of a tally stick; the Antikythera mechanism, dating from about the beginning of the first century BC, is considered to be the earliest known mechanical analog computer, the earliest known geared mechanism. Comparable geared devices did not emerge in Europe until the 16th century, it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed. Electronic computers, using either valves, began to appear in the early 1940s.
The electromechanical Zuse Z3, completed in 1941, was the world's first programmable computer, by modern standards one of the first machines that could be considered a complete computing machine. Colossus, developed during the Second World War to decrypt German messages, was the first electronic digital computer. Although it was programmable, it was not general-purpose, being designed to perform only a single task, it lacked the ability to store its program in memory. The first recognisably modern electronic digital stored-program computer was the Manchester Baby, which ran its first program on 21 June 1948; the development of transistors in the late 1940s at Bell Laboratories allowed a new generation of computers to be designed with reduced power consumption. The first commercially available stored-program computer, the Ferranti Mark I, contained 4050 valves and had a power consumption of 25 kilowatts. By comparison the first transistorised computer, developed at the University of Manchester and operational by November 1953, consumed only 150 watts in its final version.
Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, used in modern computers, dates from World War II, when a form of delay line memory was developed to remove the clutter from radar signals, the first practical application of, the mercury delay line; the first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it and delay line memory was volatile in that it had to be continuously refreshed, thus was lost once power was removed. The earliest form of non-volatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world's first commercially available general-purpose electronic computer. IBM introduced the first hard disk drive as a component of their 305 RAMAC computer system. Most digital data today is still stored magnetically on hard disks, or optically on media such as CD-ROMs.
Until 2002 most information was stored on analog devices, but that year digital storage capacity exceeded analog for the first time. As of 2007 94% of the data stored worldwide was held digitally: 52% on hard disks, 28% on optical devices and 11% on digital magnetic tape, it has been estimated that the worldwide capacity to store information on electronic devices grew from less than 3 exabytes in 1986 to 295 exabytes in 2007, doubling every 3 years. Database management systems emerged in the 1960s to address the problem of storing and retrieving large amounts of data and quickly. One of the earliest such systems was IBM's Information Management System, still deployed more than 50 years later. IMS stores data hierarchically, but in the 1970s Ted Codd proposed an alternative relational storage model based on set theory and predicate logic and the familiar concepts of tables and columns; the first commercially available relational database management system was available from Oracle in 1981. All database management systems consist of a number of components that together allow the data they store to be accessed simultan
Government of India
The Government of India abbreviated as GoI, is the union government created by the constitution of India as the legislative and judicial authority of the union of 29 states and seven union territories of a constitutionally democratic republic. It is located in the capital of India. Modelled after the Westminster system for governing the state, the union government is composed of the executive, the legislature, the judiciary, in which all powers are vested by the constitution in the prime minister and the supreme court; the President of India is the head of state and the commander-in-chief of the Indian Armed Forces whilst the elected prime minister acts as the head of the executive, is responsible for running the union government. The parliament is bicameral in nature, with the Lok Sabha being the lower house, the Rajya Sabha the upper house; the judiciary systematically contains an apex supreme court, 24 high courts, several district courts, all inferior to the supreme court. The basic civil and criminal laws governing the citizens of India are set down in major parliamentary legislation, such as the civil procedure code, the penal code, the criminal procedure code.
Similar to the union government, individual state governments each consist of executive and judiciary. The legal system as applicable to the union and individual state governments is based on the English Common and Statutory Law; the full name of the country is the Republic of India. India and Bharat are official short names for the Republic of India in the Constitution, both names appears on legal banknotes, in treaties and in legal cases; the terms "union government", "central government" and "Bhārata Sarakāra" are used and unofficially to refer to the Government of India. The term New Delhi is used as a metonym for the central government, as the seat of government is in New Delhi; the powers of the legislature in India are exercised by the Parliament, a bicameral legislature consisting of the Rajya Sabha and the Lok Sabha. Of the two houses of parliament, the Rajya Sabha is considered to be the upper house or the Council of States and consists of members appointed by the president and elected by the state and territorial legislatures.
The Lok Sabha is considered the House of the people. The parliament does not have complete control and sovereignty, as its laws are subject to judicial review by the Supreme Court. However, it does exercise some control over the executive; the members of the cabinet, including the prime minister, are either chosen from parliament or elected thereto 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 be dissolved only when the party in power loses the support of the majority of the house. The Rajya Sabha can never be dissolved; the members of the Rajya Sabha are elected for a six-year term. The executive 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 republican idea of the separation of powers. The executive power is vested in the President of India, as per Article 53 of the constitution.
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, who leads the council of ministers as described in Article 74 of the Constitution of India; 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 appointing many high officials in India. These high officials include the governors of the 29 states; the president, as the head of state receives the credentials of ambassadors from other countries, whilst the prime minister, as head of government, receives credentials of high commissioners from other members of the Commonwealth, in line with historical tradition.
The president is the de jure commander-in-chief of the Indian Armed Forces. The President of India can grant a pardon to or reduce the sentence of a convicted person for one time in cases involving punishment of death; the decisions involving pardoning and other rights by the president are independent of the opinion of the prime minister or the Lok Sabha majority. In most other cases, the president exercises his or her executive powers on the advice of the prime minister; the vice president is the second highest constitutional position in India after the president. The vice president represents the nation in the absence of the president and takes charge as acting president in the incident of resignation impeachment or removal of the president; the vice president has the legislative function of acting as the chairman of the Rajya Sabha. The
