What was the first electronic computer in the world to implement stored programs?

The first electronic digital computer to implement stored programs in the world was "EDVAC". EDVAC (Discrete Variable Automatic Computer) uses binary and is a von Neumann structure computer; it consists of five basic parts: arithmetic unit CA, controller CC, memory M, input device I, and output device O.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The first computer in the world was eniac, but the first electronic computer to realize storage was edvac.

The Discrete Variable Automatic Computer (EDVAC) is an early American electronic computer. Unlike its predecessor ENIAC, EDVAC used binary and was a von Neumann architecture computer.

EDVAC uses about 6,000 vacuum tubes and 12,000 diodes, covers an area of ​​45.5 square meters, weighs 7,850 kilograms, and consumes 56 kilowatts of electricity.

EDVAC is a binary serial computer with addition, subtraction, and multiplication functions and software functions. An addition instruction takes about 864 microseconds, and a multiplication instruction takes 2900 microseconds (or 2.9 milliseconds). Delay line memory is used, with 1000 44-bit words.

Physically includes:

• A tape recorder

• A control unit connected to the oscilloscope

• A distribution unit, used to accept instructions from the controller and memory and distribute them to other units

• A computing unit

• A timer

• Memory unit using mercury delay line

##Features:

It can be said that EDVAC is the first A modern general-purpose computer. Unlike ENIAC, the world's first electronic computer, EDVAC used binary instead of decimal for the first time. The entire computer uses a total of about 6,000 electron tubes and about 12,000 diodes, has a power of 56KW, covers an area of ​​45.5 square meters, and weighs 7850KG. It requires thirty technicians to operate at the same time.

It consists of five basic parts: 1) operator CA (2) controller CC (3) memory M (4) input device I (5) output device O;

This This architecture has continued to this day. The basic working principles of computers used today are still stored programs and program control, so computers are now generally called von Neumann architecture computers. In view of the key role von Neumann played in the invention of electronic computers, he is hailed by Westerners as the "Father of Computers".
