Computer Organization

Computer are made by many units or devices which are know as components and Elements.These devices works together in the computer so it also called computer system.
In Modern computer system the units are:
  1. Input Unit such as keyboard and mouse.
  2. System Unit/ CPU(Centrral Processing Unit)
    • Arthimatic logical Unit(ALU)
    • Memory Unit
    • Control Unit
  3. Output Unit such as Monitor and Printer
Input Device:- Input devices are the devices which used to send data and  information to the Computer. there are many types of input devices which is used in computer system they says the CPU what he do now??. Keyboard and mouse these are the important input devices.
The Work of Input devices in the computer system are:
  • They accept the information or data which is given by the user.
  • They convert the information or data from English to machine language which is understand by the CPU.
System Unit:-System unit is also called CPU.This is the Brain of the computer and main part of the computer system. without CPU computer system is not completed. The Main work of system unit is to execute the program and process the data. and it also control the other parts of the system such as Memory unit, Input unit, Output Unit e.t.c. There are three parts of the system unit:-
  1. Arthimatic Logical Unit(ALU):-This system unit do the mathematical works such asaddition , subtraction, Multiplication e.t.c and logical works. It takes the data from memory and after processing it then send back  to memory.
  2. Control Unit:- this the part of system unit the decide what work to do and control the system hardware. It ensure that the data or information are processing by the parts they work or not.
