EDVAC (Electronic Discrete Variable Automatic Computer) was made by J.W Mauchy and J.P. Eckert in 1952AD.
Physically, the computer comprised the following components:
He was the first to introduce the stored program concept in a computer.
It used a binary number system rather than decimal numbers for its operation.
It had almost 6,000 vacuum tubes and 12, 000 diodes and consumed 56 KW of power.
It covered 490 square foot of floor space and weighed nearly 7 tons.
The machine requires 30 personnel to operate.
This machine ran till 1961 at a research laboratory.
A magnetic tape reader-recorder (describes this as a wire recorder.)
A control unit with an oscilloscope.
A dispatcher unit to receive instructions from the control and memory and direct them to other units.
A computational unit to perform arithmetic operations on a pair of numbers at a time and send the result to memory after checking on a duplicate unit.
A timer.

A dual memory unit consisting of two sets of 64 mercury acoustic delay lines of eight words capacity on each line.
Three temporary tanks each holding a single word.
The EDVAC was a binary serial computer with automatic addition, subtraction, multiplication, programmed division and automatic checking with an ultrasonic serial memory.
EDVAC was a binary serial computer.
It had an ultrasonic serial memory capacity of 1,000 44-bit words.
It consumed 56 kW of power.
