The document discusses different ways to classify computers. Computers can be classified based on their purpose, the type of data they process, or their processing capacity. In terms of purpose, there are general purpose computers that can perform many tasks, and specific purpose computers designed for a single task. When classified by data type, there are analog computers that process continuous data, digital computers that process numeric data, and hybrid computers that have properties of both. Classification by capacity considers a computer's processing power, memory size, and functional capabilities. The document provides examples of analog computers and explains the differences between analog and digital computers.

2. Computer and their types
 A computer is an electronic machine which receives data,
processes it and gives result as output.
 Nowadays the computer has become a companion of the
man regarding less of the work a person does, the computer
has become his need. Because the computer not only helps
him in his business or job but alsd very useful and helpful
at home or wherever he goes.

3.  Computers have emerged in our society so that the people
think that no work is possible without computers. From
school homework to payment of bills, from reservation of
seats of aero plane or train to transect with banks, from
listening to news to researching in any field, from. Keeping
in touch with other people to finding a job, the use or help
of computer has become inevitable.
 With the increasing need of computers, the manufacturers
have brought a range of varieties of computers in the
market, which has made very difficult to classify them.
However, we can classify the computers in three ways.

4.  The purpose for which the computer is used.
 The type of data the computer processes.
 The capacity of work the computer does.

5.  When the computers are classified according to purpose
they serve, they can be of two types, General Purpose
Computers and Specific Purpose Computers. A General-
Purpose computer is a machine that can be used generally
for a variety of tasks whereas a specific purpose computer is
designed to handle a specific problem or to perform a
specific task.When we classify the computers according to
type of data they handle, then they are of three types;
 Analog Computes,
 Digital Computers
 Hybrid Computers.

6. Analog Computer:
 Analog computer measures or process data
in a continuous form. It represents
quantities like speed, weight, temperatures
etc.
 A watch or a clock is an analog device.

7. Digital Computer:
 Digital Computer process data in the form
of values ordigits or numbers. They
perform calculations and make logical
decisions.

8. Hybrid Computer:
 Hybrid Computer is the combination of properties
of both analog and digital computers. The third
way of classifying computers is based upon the
capacity of work they do. It means their
processing power or speed, functional capabilities
and size of memory etc. If we classify computers
by keeping in mind their sizes and ranges of
power and capabilities.
