Supercomputer PARAM 8000 (made by the Centre for Development of Advanced Computing (C-DAC)) was launched on July 1, 1991, is considered India's first supercomputer.

Microsoft Excel is a spreadsheet program used to store and retrieve numerical data in a grid format of columns and rows. Excel is ideal for entering, calculating and analyzing company data such as sales figures, sales taxes or commissions.

The period of third generation was from 1965-1971. The computers of third generation used Integrating Circuits in place of transistors.

Fifth Generation computers will have artificial intelligence and will be able to make "knowledge information processing system" possible.

"Spacewar" is a space combat video game developed in 1962 by Steve Russell.

Seymour Roger Cray was an American electrical engineer and supercomputer architect who designed a series of computers that were the fastest in the world for decades.

Microprocessors further revolutionized the development of computers. Personal microcomputers were possible due to the microprocessors. The first microprocessor called Intel 4004 was developed by American Intel Corporation in 1971. Microprocessors are used in the computers of fourth generation computers.

IBM 1401 is a Second Generation Computer and is the first computer to enter Nepal in 2028 BS for census. Government of Nepal had brought this computer on rent and later purchased for data processing in Bureau of Statistics. After this computer, another ICL 2950/10, a British computer, was purchased by the fund of UNDP and UNFPA for the census of 2038 BS is second computer in Nepal.

It is obvious that computers developed with more power, reliability, speed and smaller sizes due to the enhancement of technology. First generation computers used 1000s of vacuum tubes that required lot of space made them gigantic in size. Single transistor could replace 1000 vacuum tubes and a single IC chip replaced 1000s of transistors made computers smaller and more speedy.

During the period from 1956 to 1963, the second generation of computers was developed. The second generation computers emerged with the development of Transistors. The transistor was invented in 1947 by three scientists J. Bardeen, H.W. Brattain and W. Shockley.
