EDSAC

 EDVAC(electronic delay storage automatic computer), was constructed by Maurice Wilkes and his team at the University of Cambridge Mathematical Laboratory in England.

•  It used mercury delay lines for memory, and derated vacuum tubes for logic. Input was via five-hole punched tape and output was via a teleprinter.

• It has various purposes such as to solve a differential equation relating to gene frequencies, was used to gather numerical evidence about solutions to elliptic curves, etc

Additionally it has the following features:

1. The EDSAC's memory consisted of 1024 locations, though only 512 locations were initially implemented.

2. only 17 bits were used.

3. This device was the world's first practical stored program electronic computer.

4. It uses a binary number system.

5. Both input and output used paper type.

6. This machine was used to calculate a table of squares and a list of prime numbers.
