Based on Operating Principles
On the basis of operations performed and methods used to store and process the data and information,
computers can be classified into the following categories:
∑ Analog computers
∑ Digital computers
∑ Hybrid computers


ANALOG COMPUTERS
Analog computers The analog computers represent data in the form of continuous electrical signals having a specific magnitude. 

These computers are very fast in their operation and allow several other
operations to be carried out at the same time. 

Results produced by these computers are not very accurate.

Analog computers are widely used in applications in which the accuracy of
results is not a major concern. 

They are powerful tools to solve differential equations.

DIGITAL COMPUTERS

The digital computer, also known as the digital information processing system, is a type of computer that stores and processes data in the digital form. 

Data is usually stored in these computers in terms of 0’s and 1’s.

The output produced by these computers is also in the digital form. 

The digital computers are also capable of processing the analog data. 

Analog data should first be converted to the digital form, before being processed by these computers. 

Digital computers are generally faster and more reliable than the analog computer systems and provide more accurate results.









HYBRID COMPUTERS

The hybrid computer is a combination of analog computer and digital computer
because it encompasses the best features of both these computers. 

Hardware components of hybrid computers are usually the mixture of analog and digital components. 

These features make the hybrid computers very fast, efficient and reliable. 

In these computers, data is generally measured and processed in the form of electrical signals and is stored with the help of digital components. 

These computers can also be used to perform various types of logical operations. 

The input accepted by the hybrid computers is a continuously varying input signal. 

This input signal is then converted by them into a set of discrete values for performing different operations. 

These computers prove to be very cost-effective in performing complex simulations. 

The hybrid computers are also less expensive than the digital computers.
