Desktop Casing Model

2. WORKSTATION COMPUTERS

These computers are single use computer,

used for specialized job. The workstations

are considered more stronger then the

common use computer.

The workstations computers are used in :

Engineering

Animation

Architecture

3. NOTE BOOK COMPUTERS

These computers are comparative small computers

than desktop computers. They are portable in nature,

normally these computers are placed on labs hence

are also known as laptop computers.

4. TABLET COMPUTERS

These are also portable computers but lighter than

the notebook computers. They receive input from

Digital pen or Stylus.

Tablets are further types.

Hand held computers.

Smart phones.

ORGANIZATIONAL

USED

COMPUTER

1.NETWORK SERVERS

These are the combination of one or more

centralized computers. In these network

servers different user can access different

Package software

HARDWARE

The physical part of the computer is

called hardware or the physical

component that make up a system is

known as hardware.

Major Hardware Component of computer

CPU

Main Memory

Secondary Storage

Input/Output devices

CPU : CPU is called brain of a computer, it

carries instruction and perform some

arithmetic/logic operation and control input/output

operations.

Main Memory: It is also known as

primary memory, it is a volatile memory, it

store the data currently operate. It loss its

data when the switch is off, it is directly

accessible to CPU.

Secondary Storage: Secondary storage

differs from primary storage in that it is not

directly accessible by the CPU. Secondary

storage does not lose the data when the device is

powered off and it is non-volatile.

For Example : CD , Flash drive

Input/output Devices: Input devices

are used to enter data and output devices are

used to get output after processing data.

For Example: mouse , monitor
