The Indian Computer History: 6 Historic Moments

Published: 1 Oct 2015 | Last updated 7 May 2021

Computers are undoubtedly the enormously powerful tools required to drive the Indian Development Engine at top speed. Additionally, with Digital India Programme being launched by Government of India and its being supported by millions of Digital India Tricolors (Modified Profile Images) on Facebook, it’s clearly evident that computers are now an inseparable part of our lives. 

Our current Prime Minister Mr. Narendra Modi and his government deserves a salute for this initiative. With all these new ongoing developments, we also need to remember and salute the moments and icons behind them in lanes of The Indian Computer History, which gave the current initiatives a safe and strong ground to stand upon. Given below are some bright historical moments:

  1. 1953: First Indian Analog Computer
    Samarendra Kumar Mitra designed India’s first analog computer and Ashish Kumar Maity built it at ISI. It was used to compute the numerical solutions of simultaneous linear equations by applying modified version of Gauss-Siedel iteration.
  2. 1955: HEC-2M 
    Hollerith Electronic Computer (model 2M)’ was the first electronic digital computer of India, procured by ISI for a price of Rs. 10 Lakh from the British Tabulating Machine Company. In 1956, it was finally installed to program statistical calculations in machine language.
    To have an idea of what we bought for that huge amount of money, have a look at the description below:
    Length: 10 feet
    Breadth: 7 feet
    Height: 6 feet
    Keyboard: None
    Monitor: None
    Processor: None
    Memory: 3KB
    Input: Punched Cards
    Sample Computing Power: Square root of a 16 digit number calculated in 15 minutes.
  3. 1959: URAL-1
    Second electronic digital computer bought in 1959 from Russia.
  4. 1960: TIFRAC
    Formally commissioned in 1960, it was named Tata Institute of Fundamental Research Automatic Calculator by our first prime minister Jawaharlal Nehru; It was our first indigenously developed computer. It was a result of the research efforts done in the domain of computer science and electronic instrumentation, initiated at TIFR in the early 1950s.
    Powered by 2,700 vacuum tubes, 1,700 germanium diodes, 12,500 resistors and a 2,048 40-bit words of memory, it boosted  the morale of our researchers exponentially.
  5. 1969: TDC12
    ​Commissioned by Vikram Sarabhai at Bhabha Atomic Research Centre, Trombay Digital Computer was our first indigenously built electronic digital computer. It was a real‐time data acquisition computer. 
  6. 1991: PARAM 8000 
    To make India self sufficient in the field of supercomputing,  the Centre for Development of Advanced Computing (C-DAC) was set up in 1988. Nurtured with an initial funding of Rs 300 million, PARAM series of supercomputers are making India proud and proving its worth in public as well as private sector.
    Interestingly,  this whole idea of developing supercomputers indigenously came as a result of  US imposed computer export ban on India, and Rs 300 million invested initially was the amount required to procure a supercomputer from the US.
    PARAM Yuva-ll was the ninth supercomputer unveiled under the PARAM series in 2013. 

We salute all the known as well as lesser known individuals, who made everything above possible. We are also thankful to the previous governments who funded the above activities and made progressive policies to support them. Finally, we make an appeal to each and every Indian alive to support this dream beyond the digital world of social media, and contribute as much as possible, whenever required.
