Classification of the Computer:

• Computers are becoming more and more advanced everyday. 
• We use computers altogether areas of our lives to try to to different sorts of work.
• There are differing types of computers having different features.
• Computers are often classified supported their size technology purpose.

The Computer are classified into three main types:

1. Analog Computers Analog

2. Digital Computers

3. Hybrid Computers (Analog + Digital)

Analog Computers:

• Analog Computer measures “Physical Quantities” for instance Temperature, Voltage, Pressure, and current .
• The analogue computer are utilized in scientific and industrial ventures, where they need to screen temperature,voltages and electric currents.

Examples of Analog Computer ::

• Speedometer
• Thermometer

Micro computers or personal computer:

A micro computer is that the commonest sort of computer, weather during a works place at college or on the desk reception .

Main Features:

• The CPU of your micro computer may be a single chip referred to as the microprocessor.
• These are single user computers.
• They are mainly utilized in offices and houses .
• They are the smallest amount expensive.

Examples:

Desktop computers:

These are the foremost common sort of computers also referred to as personal computers.

Laptop or notebook computers:

• These are portable computers that use these computers are often carried around.
• They can run on rechargeable batteries.
• They run on an equivalent operating systems as personal computers like Windows, Linux , iOS, etc.

Tablet PCs:

These are mobile computers with touch screen.

Smartphones, Smart books and PDAs (Personal Digital Assistants):

• These are small hand-held computers.
• Tablets and smartphones operate mobile operating systems like Android iOS Windows phone or symbian.

Programmable calculators:

They are small hand-held, but specialised on mathematical work.

Game consoles:

Computers like Xbox specialised for entertainment purposes.

Embedded computers:

• These are computers built into machines like carpet built into a car for entertainment and navigation.
• Washing machines watches ATMs exedra even have embedded computers.

Workstations:

Workstations are powerful single user computers.

Main features:

they are used for task that need an excellent deal of power like in computer animations are scientific and mathematical work.

Example:

computers utilized in banks and weak offices like software companies and scientific organisations.

Mini computers:

Mini computers are more powerful than micro computers.

Main Features:

• A mini computer may be a multi-user computer, or , many of us can use one machine at a time.
• It has greater storage capacity than a micro computer.
• It may be used as a network and internet server.

Example:

PDP-II, SPARC, POWER Architecture and Itanium-based systems from Sun Microsystems, IBM and Hewlett-Packard.

Mainframe Computers:

• Mainframe computers are very large and powerful computers.
• if you ever used an automatic teller machine to interact with their checking account you used a mainframe.

Main features:

• They are faster more powerful and costlier than micro computers or mini computers.
• They are utilized in large organisations like banks and government offices where many users need access to shared data and programs.
• They are used as e-commerce service for handling transactions over the web .

Examples:

VAX 8842, CDC 6600, IBM 4381.

Super Computers:

Super computers are the foremost powerful of all computers.

Main features:

• They are the foremost expensive computers.
• They are massive in size and may occupy an entire .
• They have several processes which make them very powerful and fast.
• They are used for problems requiring complex calculations.
• Super computers are utilized in areas like meteorology nuclear science seismology Excel they're widely utilized in universities and government agencies.

Examples:

CRAY XT5-HE, India’s PARAM, IBM – Blue Gene/P Computer.

Hybrid Computers:

• It should be a mix of analog and digital computers. Devices like these have managed to mix the simplest features of analog and digital, making them super important during a number of areas.
• In terms of where hybrid computers are used, they are mainly found in specialized applications that need to process analog and digital information.
