  • Classification of Computer for Competitive Exams

    Computer Classification
    Image Source Pexel.com

    Dear Readers, In this post Classification of Computer is given. Basically Computer is an electronic machine that accepts data (input) from the user, processes the data by performing calculations and operations on it and then generates the desired results (output) to the user.

    Computers are mainly classified on the basis of Size, Work and Purpose as following:

    Computer Classification on the basis of Size

    On the basis of size, computers are classified as (i) Micro Computer, (ii) Mini Computer, (iii) Mainframe Computer and (iv) Super Computer as below:

    (i) Micro Computer

    Micro computers are the most widely used computers. They are also called portable computers, though they are the least powerful. Types of Micro computers are following:

    • Personal Computer (PC)
    • Laptop
    • Tablet
    • Handheld Computers
    • Personal Digital Assistant (PDA)
    (ii) Mini Computer

    Mini computers are more powerful and costly than Micro computes. They were designed initially for CAD (Computer Aided Design) related works but now they are used as central computer. E.g. IBM-17, HP-9000 etc.

    (iii) Mainframe Computer

    Mainframe computers are larger, faster and cost higher than Mini computers. They have large internal memory, computing and storage. They also have comprehensive range of softwares. E.g. IBM S/390/, UNIVAC 110 etc.

    (iv) Super Computer

    Super computers are fastest and the most expensive type of computers. They have very high processing speed. Their speed measurement unit is FLOPS (Floating point operations per second). E.g. CRAY-1, PARAM etc.

    Computer Classification on the basis of Work

    Computers are also classified on the basis of the work as (i) Analog Computer, (ii) Digital Computer and (iii) Hybrid Computer as mentioned below:

    (i) Analog Computer

    Analog computers are job oriented computers. They can perform several mathematical operations simultaneously. E.g. seismograph, speedometers etc.

    (ii) Digital Computer

    Digital computers work on the binary digits. They also perform mathematical calculations and produce desired results (graphics, sounds). E.g. Desktop (PC), Laptop etc.

    (iii) Hybrid Computer

    Hybrid computers are the combination of analog and digital computers. Several machines used in hospitals like DIALYSIS and ECG are the commonly used hybrid computers.

    Computer Classification on the basis of Purpose

    On the basis of purpose, computers can be classified as (i) General Purpose Computer and (ii) Special Purpose Computer as below:

    (i) General Purpose Computer

    The main use of General Purpose computers are to solve various types of problems bu using various types of programs, applications, software etc. E.g. to make small database, calculations, accounting etc.

    (ii) Special Purpose Computer

    The use of Special purpose computers are to solve a single particular type of problems. E.g. Automatic Aircraft Landing etc.
