According to internal processing computers can be classified into three main types namely digital computers, analog computers and hybrid computers. 1. ... A digital computer represents data in the form of discrete numbers and processes data using the standard arithmetic operations.

2. OVERVIEW AND HISTORY
1. Computer systems may be classified according to the data they
are designed to process or they may be classified according to
their size and capabilities.
2. The data required for processing may be obtained either as a
result of counting or through some measuring device.
3. Data obtained through counting is known as discrete data, while
that obtained through measuring instruments is known as
continuous data.
4. An example of discrete data is the number of marks obtained by a
student in an examination, while the constant monitoring of the
Electro-Cardiogram of a patient is an example of continuous data.

3. THERE ARE THREE TYPES OF COMPUTER UNDER THIS CATEGORY.

4. ANALOG COMPUTER
1. Computers that measure the continuous physical magnitude or
electrical states.
2. For example pressure, temperature, voltage, volume, etc.
3. A speedometer in a vehicle is another example of analog
computer.
4. Analog computers are used for scientific, engineering & process
control purposes.
5. Since they deal with quantities that are continuously varying in
nature, they give only approximate result i.e. Not accurate results
as in digital computer.

5. ANALOG COMPUTER

Laboratory circa 1949.

6. DIGITAL COMPUTER
1. computer designed to processed data in discrete numerical
form which are represented by discrete signal using binary code,
numbers, letters, and symbols are represented by codes based on
the binary number system consisting of two digits
2. .i.e. 1,0 the digital computer must convert all data to binary form.
Generally, results from digital computer are more than the results
from analog computers.
3. They are used for counting and calculating numbers. Examples
are calculator, adding machine, counting machine, etc.

9. HYBRID COMPUTER
1. A hybrid computing system is one in which desirable
characteristics of both the analog and digital computers are
integrated.
2. n an intensive care unit, analog computers may measure the
patient’s heart rate, temperature, etc.
3. The measurements may then be converted into numbers and
supplied to the digital part of the system which will thereafter
regulate the flow of certain medications.
4. They can be used for both counting and measuring. In fact, they
are very useful in the control of manufacturing and processing.
