Electronic Discrete Variable Automatic Computer (EDVAC)

In 1949, the first electronic computer was developed by John Mauchly and John Presper Eckert with the help of A. Burks, Goldstine and Numann. This machine was used to storage the data and information as well as the instruction. This computer operated electronically.

Electronic Discrete Variable Automatic Computer (EDVAC) was one of the earliest electronic computers. It was the first stored program computer. Like the ENIAC, the EDVAC was built for the U.S Army's Ballistics Research Laboratory by the University of Pennsylvania's Moore School of Electrical Engineering.

This Computer Was developed by J. Presper Eckart and John William Mauchly using the concept of Hungarian mathematician, John Von Neumann. The EDVAC was completed in 1952. It was based on binary number system and used magnetic tape for storing data and instructions.

The EDVAC was a binary serial computer with automatic addition, subtraction, multiplication, programmed  division and automatic checking with an ultrasonic serial memory. The Computer has almost 6000 vacuum tubes and 12000 diodes, and consumed 56KW of power.

It covered 490ft2 (45.5 Msq.) of floor space and weighed 17300 lb (7850 kg).
