Accepted Answer

CPU is the brain of the computer.its basic function is to perform calculations and various logical functions.
There are there parts of CPU.
1.Control Unit
2.ALU(Arithmetic and Logic Unit
3.Memory.
Control Unit:-Selects,interprets and executes instructions.
Monitor input or Output operations and guides the routing of data between storage  location and the arithmetic and logic unit.
ALU:-Performs calculations and comparisons.
Work at tremendous speed and executes millions of instructions per second (MIPS).
Memory :- Memory is also called internal storage or main memory or random access memory (RAM).
Consists of very fast memory like magnetic core memory or semiconductor memory.
Stores program instructions or part of data for immediate need.
Data is stored in a computer memory in the form of words, bytes and bits.
