Computer Systems Diagram: What is a Computer System Unit? In this article , we will learn computer system block diagram and all the components of a computer

A computer system unit is a block that contains the main components of a computer. It is also refereed to as a case or tower.

Computer Systems Diagram Definition.

Any desktop computer has a computer unit system unit; a keyboard, a mouse, and a monitor. A computer system is the enclosure of all the other main interior components of a computer. A computer system has the computer chase, computer chassis, or the computer tower.

The computer case are made of either steel or aluminum but also plastic can also be used. Most cases are made to be dull, metal boxes. Manufacturers nowadays are mindful of designs and color in the 21 century.

Input

The functions of the input system is to;

  • Take the data to be processed by the user.
  • Convert the given data into machine-readable form.
  • The sole purpose is to connect the user and the computer. In addition, this creates easy communication between them.

CPU(Control Processing Unit)

Central Processing Unit or the CPU, is the brain of the computer. It works the same way a human brain works. As the brain controls all human activities, the CPU too controls all tasks.

ALU(Arithmetic Logic Unit)

The main function of the ALU is to;

  • Performs the basic arithmetical operation on it.

Control Unit

The control unit as the name suggests is the controller of all the activities/tasks and operations. All this is performed inside the computer.

Memory Unit

There are two Memory units ;

  1. Primary Memory
  2. Secondary Memory
