CPU-Control Proccesing Unit- What is CPU-How perform the CPU

·         CPU ( control processing unit):-

 “CPU” is the Main part of any computer. It reads and executes program instruction, perform calculation and makes decisions. Most of the device connected to the computer communication with CPU is also called micro processor”.

It consists of three main components namely-

i.                    Control unit:

The control unit controls and co-ordinate the activities of all other components of the computer. It instruct the arithmetic logic unit as to which operation has to be performed arithmetic logic unit as to which operation has to be performed. Its act like control nervous system for all the components, naught it does not process any data.

ii.                  Arithmetic logic unit (ALU) : -

The arithmetic logic unit is the part of CPU where logical and arithmetic calculation are logical and arithmetic operations include addition (+), subtraction (-), multiplication (*) , and division (/). Logical operation includes comparison of numbers. (><+ not = ); letter and special characters. 

                                    The data is fed into the memory unit by with the help of input devices, this data is then from furred to the arithmetic logical units and when needed for processing by the control units.

                        The arithmetic logical unit responds to the command coming from the control sections. Once the data is processed the results are direct to the memory sections for processing. it also holds the processed information’s.

·         Working of the central processing unit: -

      The control processing unit gets the instructions from the memory. It directs about the instructions and directs the necessary data from the memory the arithmetic logical unit. The arithmetic logical units then executes the instructions the control unit then directs the result from the arithmetic logical unit to the memory. Where it is stored. Finally the results are by means of output device.

                  This can be best illustrated with the help of on example, of additions of two members “4” and “5” the numbers are enter input through on input device and store in memory , then the control units directs the input to the arithmetic logical units and signals it to performthe additions ot two numbers takes place the ALU and the result. It is moved to the memory . finally the results is displayed using on output device.

                                               Signal the ALU  to perform the                       

                                                Addition of the numbers

Number = 2x 5                  Result=20

                          

                                             

 

Adds up the Numbers Result+20
