Electronics Club website is a place for any student or people, those are interested to know about the basic ideas of Electronics and Communication Engineering.
The Von Neumann Architecture
In 1945 Jone von Neumann was the first published architecture of the computer, which was known as Von Neumann architecture. According to Von Neumann Architecture, The basic function performed by a computer is the execution of a program. A program is a set of machine instructions. An instruction is a form of control code, which supplies the information about an operation and the data on which the operation is to be performed. A typical Von Neumann machine consists of five functionally independent units :
Input unit
Output unit
Arithmetic and logic units
Control unit
Memory unit
Central Processing Unit (CPU)
The Central Processing Unit (CPU) is the electronic circuit responsible for executing the instructions of a computer program.
It is sometimes referred to as the microprocessor or processor.
Arithmetic and Logic Unit (ALU)
The ALU allows arithmetic (add, subtract etc) and logic (AND, OR, NOT etc) operations to be carried out.
Control Unit (CU)
The control unit controls the operation of the computer’s ALU, memory and input/output devices, telling them how to respond to the program instructions it has just read and interpreted from the memory unit.
The control unit also provides the timing and control signals required by other computer components.
