hy friend hope my ans. helps uh a lot...
The three components of the CPU are following,
1. Arithmetic Logic Unit
2. Control Unit
3. Registers
Arithmetic Logic Unit (ALU)
There is electronic circuitry in arithmetic logic unit which executes all airthmetic and logical operations.Its function is obvious from its name.It performs arithmetic calculations like as addition, subtraction, multiplication and division as well as comparisons.The unit can compare numbers, letters, or special characters.
Control Unit(CU)
There is circuitry in the control unit which uses electrical signals to instruct the whole computer system for carrying out or executing,already stored program instructions.Its name clearly shows that it controls and co-ordinates computer components.It extracts instructions from memory and decodes and executes them.In fact it regulates the flow of information through the processor.
Registers/The Memory Unit
Registers are temporary storage areas which are responsible for holding the data that is to be processed.They store the instructions and data in a processor.This data is further used by Control Unit.There are some registers that are set aside for specific tasks, these generally include a program counter, stack, and flags.
