CENTRAL PROCESSING UNIT.

                                       Central processing unit also called the heart of the computer. This consist of three parts;

1.Control Unit (Cu).

2. (Arithmetic and Logic Unit (ALU).

3. Memory.

 

1 . Central Unit (CU).

                                All the controlling of the computer is done by this unit. This controls all the parts of the computer is giving the required command when necessary.

2 . Arithmetic and Logic Unit (ALU).

                                      This unit does all kinds of calculations and reasoning.

3 . Memory.

                                The memory is used temporarily to store the data which are ready to be sent to the central processing unit for calculations or processing and the information which are ready to be sent out from the central processing  unit. two kinds of memory can be seen in computer.

     1. Random Access Memory – (RAM)

           2. Read Only Memory – (ROM)
