The Classification of Computer types.

The Classification of Computer types.

The Classification of Computer types can be categorized into 03 computer types and these types of computers. Computers are used to perform different types of functions. These types of computers depending on the nature of work they perform and the way the get the input and produce the output.

Computer Types

• Digital Computer (which are used for General Purpose and are called general purpose Computers).
• Analog Computers (which are used for Special or Specific and are called Purpose Computers).
• Hybrid Computers (which are used for Special or Specific Purpose and are called Computers).

Digital Computer.

The computers you use commonly at your offices, Universities, colleges, and homes these computers are called digital computers. These computers are high in speed, and these computers are programmable electronic devices that they perform mathematical calculations compare values and store results.

Numbers (or digits) that represents numerals letter or other special symbols are reduced to representation by 1s and 0s that are why they are known as digital computers.

Analog Computers.

These are called special or specific purpose computers because they are designed for a special purpose and they perform that particular job only all measuring devices are called analog computers it works on continuous data and deals with the physical quantities the output is usually in the form of readings on dials or graphs a furnace, thermostat a fuel pumps a speedometer of a car and an ECG machine are the best examples of analog computers.

Hybrid Computers.

These are also special or specific purpose computers because they perform a certain set of jobs these are highly sophisticated systems used in sensitive areas mainly in the research laboratories and defense a hybrid computer is a combination of digital and analog computers the radar systems installed at airports and defense installations are also examples of hybrid computers.
