Full Form of ENIAC

The full form of ENIAC is “Electronic Numerical Integrator And Computer”. ENIAC was the first programmable, electronic, general-purpose digital computer, completed in 1945. Other computers had this specification, but the ENIAC had all of them in one package. It was Turing-complete and able to solve “a large class of numerical problems” through reprogramming.


ENIAC was the first programmable, electronic, general-purpose digital computer, completed in 1945. It was the world’s first general-purpose electronic computer, which was designed to be a modular computer made of separate panels that perform separate functions and run only on electronic components without having any mechanical part to slow it down. ENIAC’s weight was around 30 tons and was spread over an area of 1800 square feet. The full form of ENIAC is explained here.

Component of ENIAC

Earlier we described the full form of ENIAC and now we will discuss some important components of ENIAC. The main component of ENIAC include.
  1. 18,000 vacuum tubes
  2. 15,00 relays
  3. Resistors
  4. Capacitors
  5. Inductors
Furthermore, it had 20 single-number accumulators as primary functional units along with special units for division, multiplication, and square roots. So, it was not only used by the army but was also suitable for weather prediction, wind-tunnel design, atomic-energy calculations, thermal ignition, cosmic-ray studies, etc. Later, it became obsolete when there was a need for faster computing speeds over time.

Development and Design

ENIAC’s design and construction were financed by the United States Army, Ordnance Corps, and Research and Development Command, led by Major General Gladeon M. Barnes. The full form of ENIAC is described here. The total cost was about $487,000, equivalent to $5,940,000 in 2020. The construction contract was signed on June 5, 1943; work on the computer began in secret at the University of Pennsylvania’s Moore School of Electrical Engineering the following month, under the code name “Project PX”, with John Grist Brainerd as principal investigator. Herman H. Goldstone persuaded the Army to fund the project, which put him in charge to oversee it for them. The Full Form of ENIAC is defined here.
ENIAC was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania, U.S.The team member of design engineers assisting the development included Robert F. Shaw (function tables), Jeffrey Chuan Chu (divider/square-rooter), Thomas Kite Sharpless (master programmer), Frank Mural (master programmer), Arthur Burks (multiplier), Harry Huskey (reader/printer) and Jack Davis (accumulators).

ENIAC weighed 30 tons, took up 1,800 square feet of space, and was made of 17,468 vacuum tubes, 1,500 relays, 70,000 resistors, 10,000 capacitors, and nearly five million hand-soldered joints.

What is the first software?

Google released a tribute to the Manchester Baby, celebrating it as the “birth of software”. FORTRAN was developed by a team led by John Backus at IBM in the 1950s. Know about the full form of ENIAC.
