Microprocessor (Introduction to Computer Continued)

The Microprocessors:-

The Microprocessor is the brain of computer. A microprocessor is is an integrated circuit that contains a complete CPU on a single chip. It is simply called CPU. CPU is central component of computer. The processor performs the calculations and processing for the computer. There are 2 main units of a Computer Processor.
Arithmetic and Logic Unit
Control Unit

Arithmetic and Logic Unit:-
This Part of the CPU. All the operation of Arithmetic and logic are Performed by ALU. The data on which any operation is to be taken is fed to computer memory with the help of Input device. That is then assigned to ALU for further operations. ALU is actually combination of two units.

Logic Unit

Arithmetic Unit:-

The Arithmetic unit of ALU performs the fundamental operation of arithmetic such as addition, subtraction, multiplication and division.

Logic Unit:-

This unit of ALU does all the operation of data involving between two values. The logical operation include the comparison between two numbers to define which number is greater, less, equal or not equal to a number.

Control Unit:-

CU is responsible for the execution of the program instruction given to the computer.The Input and Output Devices also depend on the CU.
It accepts the data from input devices and transfer it to the main memory. Then it transfer data from the main memory to ALU. At the end it sends the output either to main memory or output devices.
