Computer can be classified in several ways: 1. By operating principles - analog, digital, and hybrid computers. Analog computers use continuous physical variables while digital computers use discrete values. Hybrid computers use both. 2. By application - general purpose computers which can perform many tasks with less efficiency, and special purpose computers designed for specific tasks. 3. By size and capability - microcomputers are the smallest, minicomputers are larger but serve as servers, mainframes are high-performance for bulk data, and supercomputers have extremely high processing power.

1. Computer and its
classification
Assignment Date : 21.07.2017

2. Computer
The computer is an
electronic device which
accept the input data
processing according to
their instruction and it
gives output results.

3. Computer basic
An electronic device that is design to work with
information it is an advance device that takes raw data as
input from user and process the data under control set of
instruction and gives the result saving output for future
use. It can process both numerical and Non-numerical
calculations

4. Classification
Based on operating principles –
1. Analog Computer
2. Digital Computer
3. Hybrid Computer
Based on Applications-
1. General Purpose
2. Special Purpose
Based on size and capability of computers –
1. Micro Computer
2. Mini Computer
3. Main frame Computer
4. Super Computer

5. Based on Operating Principles.
1. Analog Computer :-
They employ electrical
parameters such as
voltage, resistance, current
to represent to being
manipulated. These
computer uses continuous
physical phenomena such
as
electrical, mechanical or hydraulic quantities to model
the problem being solved.

6. Based on Operating Principles.
2. Digital Computer :-
A computer that
performs calculations
and logical operation
with quantities
represented as digits
usually in the form of
binary number system.
They are more accurate
and much faster

7. Based on Operating Principles.
3. Hybrid Computer :-
A combination of
computers that are
capable of taking input
and producing output
in both analog and
digital forms. This type
of computers
system set up offer a cost effective of
performing complex simulations.

8. Based on Application.
1. general purpose computers:-
This type of computer a
design to perform a
range of task but these
computers lack in
efficiency.

9. BASED ON APPLICATION.
2. SPECIAL PURPOSE COMPUTERS:-
They are design to
handle a specific
problem or to perform
specific task.

10. BASED ON SIZE AND CAPABILITY
1. MICRO COMPUTERS:-
A small computer with
a micro processor as its
CPU. It includes a
micro processor,
memory, minimum
input or output
circuitry.

11. BASED ON SIZE AND CAPABILITY
2. MINI COMPUTERS:-
Physically small
computers but with most
of the features and
capability of large
computers they are
generally used as servers
operating business
application.

12. BASED ON SIZE AND CAPABILITY
3. MAIN FRAME COMPUTERS:-
Ultra high
performance
computers make for
high volume and
processor intensive
computing. They are
used for bulk data
processing.

13. BASED ON SIZE AND CAPABILITY
4. SUPER COMPUTERS:-
A computer with high
level computational
capacity as compare to
any other computer.
Millions of times
father than a desktop
P.C. very high
processing, power, and
design.
