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
