Memory and Processing

The Microprocessor is the key processing unit also called the central processing unit (CPU) that Interprets and carries out all the basic instructions that operate the computer.

Processor contains a Control Unit (CU) and an Arithmetic Logic Unit (ALU).

These two components work together to perform processing of operations. For every instruction, a processor repeats a set of four basic operations that makes the machine cycle which is mention below:

     1. Fetch:                   get data from main memory

     2. Decode:               Convert Data to machine understandable language.

     3. Execute:              Perform Calculation on data.

     4. Store:                    Store the results in main memory.
