    ` Special Purpose

    Desinged for a particular application only.

    Instructions to be executed are permanently stored. Handle very narrow categories of processing like

    x Air Traffic Control

    x Printing

    x Assembling machine parts

    ` General Purpose

    Can work on different types of programs supplies.

    Can be used in number of Applications Instructions are not permanently stored but provided at

    the time of execution.

    ` Micro Computers Most frequently used computers

    Better known by the name Personal Computers

    Meant for public use

    Can be further categorized into

    x Programmable Computers

    x Personal Computers

    x Workstations

    x Servers

    ` These vary in their computation power, speed,

    memory and size.

    ` The smallest ones can be held in palm.

    ` These are known as Personal Digital Assistants(PDAs)

    ` When equipped with Cell phones, PDAs can

    connect to Wireless Computer networks to

    exchange information

    ` Generally used in Business and at home for word

    processing, entertainment, communication and

    other applications.

    ` Have a large amount of storage so as to storethousands of programs and documents

    ` Consists of Desktops and Laptops.

    ` Laptops are more compact in size and have less

    weight.

    ` Same as Personal computer but have large

    memory and more mathematical abilities.

    ` Specially found in scientific, industrial fields which

    require high levels of computational power.` Often have very high resolution and accelerated

    graphics handling capabilities which make them

    suitable for advanced architectural design work.

    ` Very powerful computers.

    ` Number of personal computers and terminals can

    be connected to the server.

    ` Have a very large disk storage and RAM` Can have more than one processor

    ` Computers connected to the server are called

    clients.

    ` This is known as client-server architecture.

    ` Were used to control machines in manufacturing

    units.

    ` Defined as small general purpose computer that has

    computing power larger than that of microcomputers.` Can support simultaneous working of up to 100 users

    and is usually maintained in business organizations

    for the maintenance of accounts and finances.

    ` Computers used by large organizations involved inmeteorological surveys and statisticalmathematics.

    ` They are designed for handling huge amount ofdata and information.

    ` Have great processing power and very largestorage capacity as compared to mini computers

    ` Core computers which are used for desktop

    functions of over 100 hundred userssimultaneously.

    13/16

    ` Somewhat similar to mainframe computers and

    are used in economic forecasts and engineering

    designs.

    ` These are the largest and fastest computers.` Consists of several processors running together

    there by making them immensely faster and

    powerful.

    ` Almost an extinct type of computer. It is different

    from digital computers in respect that it can

    perform numerous mathematical operations

    simultaneously.` Utilizes mechanical, hydraulic or electrical energy

    in operation

    15/16

    ` These type of computers are, as the name

    suggests, a combination of best features of analog

    and digital computers.

    ` They have the speed of analog computers andaccuracy of digital computers.
