Objective
• Get an understanding of the 6
Basic Internal Components of a
Computer System.
Internal Components of a Computer
Systems
• Processor (CPU)
• Main memory
• I/O controllers.
• Address bus
• Data bus
• Control bus
The CPU
• The Brains behind
the computer
• Central Processing
Unit
• Memory – Registers
• Memory for
Programs
sdff
Memory
• This is the place where information in the
form of binary digits are stored
• The binary digits represent both the
Instructions, and the data on which the
instructions are carried out.

What is a Bus?
According to computer
architecture, a bus is
defined as a system that
transfers data between
hardware components
of a computer or
between two separate
computers.
It is a set of Parallel
wires connecting two or
more components of a
computer.
The Bus connects the Hardware.
Internal Components of a Computer
Systems
• Processor (CPU)
• Main memory
• I/O controllers.
• Address bus
• Data bus
• Control bus
A little Exercise
• In your Revision
notebook, draw
and label a
diagram of the
internal
components of a
computer system.
In the Next Video….
• Understand the role of the computer
system components and how they
relate to each other.

Editor's Notes

  1. Welcome to part 1 of a series of videos on Computer Organisation and Architecture. In these videos I’ll be breaking down how the computer works from the inside, and youll be able to draw and label a diagram of a cpu system.
  2. And here they are. The 6 basic internal components of a computer system. They are 1,2,3,4,5, and six. You will need to remember these components for any computer science exam.
