1. TOPIC -> CLASSIFICATION OF COMPUTERS
BY:
TUSHAR MISHRA

4. 1.) General Purpose :
• Handle variety of tasks,
•Versatile,
• Less efficient,
EXAMPLE – Personal Computers,Tablet etc.
2.) special Purpose :
•Dedicated to a specific tasks,
• Faster processing,
• More efficient due to specialized programs,
EXAMPLE – Play Station, Missile Guidance System etc.

5. 1.) ANALOG COMPUTERS
2.) DIGITAL COMPUTERS
3.) HYBRID COMPUTERS

6. Analog Computer measures and answer the questions by the
method of “HOW MUCH”. The input data is not a number its a
physical quantity like temperature, pressure, speed, velocity.
 Signals are continuous of (0 to 10 V).
 It works by measuring data.
 High speed
 Output is continuous
 Used for measuring Current, Temperature, Speed etc.
 EXAMPLE:-
Speedometer, Clock, Electric Meter etc.

8. ...DIGITAL COMPUTER…
Digital Computer counts and answer the questions by the
method of “HOW Many”. The input data is represented “by
the number (binary form (0,1))”. These are used for the
logical and arithmetic operations.
• Signals are two level of (0 V or 5 V).
• They work by computing data.
• Output is continuous but
obtain when computation is
completed.
• EXAMPLE :-
Stop Watch, Electronic Watch etc.

9. ...HYBRID COMPUTER…
The combination of features of analog and digital computer
is called HYBRID COMPUTER. They work by measuring
and also counting data.
EXAMPLE :- Central National Defense and passenger flight radar
system.
They are also used to control robots and space exploration.

10. 1.) micro COMPUTERS
2.) mini COMPUTERS
3.) mainframe COMPUTERS
4.) super COMPUTERS

11. ...microCOMPUTER…
Micro computer are the smallest computer
system. There size range from calculator to
desktop size. Its CPU is microprocessor. It
also known as Grand Child Computer.
Application :-
• personal computer,
• offices.

12. ...miniCOMPUTER…
These are also small general purpose system. They
are generally more powerful and more useful as
compared to micro computer. Mini Computer are
also known as Mid Range Computer or Child
Computer.
Application :-
• Departmental systems,
• Network Servers,
• Work group system.

13. ...mainframeCOMPUTER…
Mainframe computers are those computers that
offer faster processing and grater storage area. The
word “main frame” comes from the metal frames. It
is also known as Father Computer.
Application :-
• Host computer,
• Super server.

14. • Super computer are those computer which are
designed for scientific job like whether forecasting
and artificial intelligence etc. They are fastest and
expensive as well. A super computer contains a
number of CPU which operate in parallel to make it
faster. It also known as Grand Father Computer.
• Application - whether forecasting, weapons
research and development.
