IT departments are allocated funds by senior leadership and must attempt to achieve the desired deliverables while staying within that budget. Government and the private sector might have different funding mechanisms, but the principles are more-or-less the same. This is an often overlooked reason for the rapid interest in automation and Artificial Intelligence , but

The Maharatna public sector units can now decide on investments of up to 15 per cent of their net worth in a project while the Navaratna companies could invest up to ₹1,000 crore without explicit government approval. Two categories of Miniratnas afford less extensive financial autonomy.

Their definition consists of three categories: techniques for processing,

By the year of 1984, according to the National Westminster Bank Quarterly Review , the term information technology had been redefined as "The development of cable television was made possible by the convergence of telecommunications and computing technology (…generally known in Britain as information technology)." We then begin to see
3149-628: The establishment of basic and heavy industry was fundamental to the development and modernisation of the Indian economy. India's second five year plan (1956–60) and the Industrial Policy Resolution of 1956 emphasized the development of public sector enterprises to meet Nehru's national industrialisation policy. His vision was carried forward by V. Krishnamurthy , a figure known as the "Father of Public sector undertakings in India". Indian statistician Prasanta Chandra Mahalanobis

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 in 1956, as

Building upon the Bombay Plan , which noted the necessity of government intervention and regulation in the economy, the first Industrial Policy Resolution announced in 1948 laid down in broad strokes such a strategy of industrial development. Later,
3886-536: The status of Maharatna , Navaratna , and Miniratna (Category I and II). Following India's independence in 1947, the limited pre-existing industries were insufficient for sustainable economic growth .

The government initially prioritized strategic sectors, such as communication, irrigation, chemicals, and heavy industries , followed by

The advantages of e-mail are: easily perceived and remembered by a person addresses of the form user_name@domain_name (for example, somebody@example.com);
4087-405: The world's storage capacity per capita required roughly 40 months to double (every 3 years); and per capita broadcast information has doubled every 12.3 years. Massive amounts of data are stored worldwide every day, but unless it can be analyzed and presented effectively it essentially resides in what have been called data tombs: "data archives that are seldom visited".

Giving them such credit for their developments, most of their efforts were focused on designing the first digital computer. Along with that, topics such as artificial intelligence began to be brought up as Turing
