The Computer System


Welcome to Class !!

We are eager to have you join us !!

In today’s Computer Science class, We will be discussing The Computer System. We hope you enjoy the class!



A computer is an electronic device that has the capability of accepting data through the input devices and processes it on the system unit and produces meaningful output called information with the aid of a stored program.

Components of a Computer System

There are three (3) major components which will determine the performance of the computer. They are:

  1. Hardware
  2. Software
  3. Peopleware


Hardware Components

A computer is made up of multiple physical components of computer hardware upon which operating system can be installed and other software to perform the operators desired function or tasks.

Therefore, it is the physical part of the computer which can be seen and touched. Simply, it is the tangible components of the computer.

The computer hardware is responsible for performing four (4) basic functions:

  1. Input
  2. Processing
  3. Output
  4. Storage

The hardware includes:

  1. CPU (which comprises of ALU, control unit, memory).
  2. Input devices or unit.
  3. Output devices.

Software Components

The computer software also called a program is a collection of instructions that enable the hardware to function effectively. Without the software, no computer can function. It controls and directs the hardware on what to do.

There are basically two (2) major types of software namely:

  1. System Software
  2. Application Software
Peopleware Components

Peopleware is a term used to refer to one of the three core aspects of computer technology i.e. hardware, software and peopleware.

Peopleware can refer to anything that has to do with the role of people in the development or use of computer software and hardware components.

Peopleware can be divided into two distinct groups:

  1. Computer professionals
  2. Computer user




We have come to the end of this class. We do hope you enjoyed the class?
