USED
COMPUTERS

6. 1. DESKTOP COMPUTERS
Desktop are the most common type of
single use computer. Normally it use one
processor for processing, however

 MODELS OF DESKTOP COMPUTERS
 Tower Casing Model
 Desktop Casing Model

7. 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

8. 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.

9. 4. TABLET COMPUTERS

the notebook computers. They receive input from
Digital pen or Stylus.
 Tablets are further types.
 Hand held computers.
 Smart phones.

10. ORGANIZATIONAL
USED
COMPUTER

11. 1.NETWORK SERVERS

computers. They are used to perform
complicated tasks. Like weather
forecasting , nuclear fusions etc.

15. ANY QUESTION

 Drivers etc.

20. APPLICATION SOFTWARE
Software that has been design to solve a
specific problem, or to provide audio , video ,or
multimedia entertainment to the user.
 Categorizes:

 Package software

21. 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

22. 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.

23. 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
