– System
A computer is an integrated form af different components that
work together to give a desirable result. It has different component and each works
for a specific purpose; however, they generate common result as required by the
user.
Component
of the Computer System
Let us understand the following basic components of a
computer system.
- Hardware
- Software
- Humanware
- Firmware
- Birdgeware
Hardware
The physical components collectively from the hardware of a
computer system. Hardware comprises of the equipment that helps in the working
system of the computer.
Following are the different types of hardware components
(which have specific function) –
- Monitor – It displays (visual) the result.
- CPU – It is the Central Processing Unit that controls the computer’s functions and transmits data.
- Motherboard – It is mainly accountable to establish communication between components and transmission of information.
- RAM - It is the Random Access Memory and responsible for the storage of programs that are currently running and also stores data temporarily.
- Hard Disk Drive – It is a permanent memory storage device.

Software
The hardware components can only
function when software components are added to the computer system. Software is
a program that performs different commands given by user.
Software is an intangible part of
hardware and controls the sequence of operations.
Types of Software
Depending on the basic features
and functionality, software can be categorized as-
- Operating System (OS)
- Application Software (AS)
- E-accessibility Software
Let us now discuss the software components in brief.
