 CLASSIFICATION OF COMPUTER 

  

-- COMPUTER ARE MAINLY CLASSIFIED AS TWO TYPES FOLLOWS;

                 .BASED ON WORK                         .BASED ON SIZE

                1. ANALOG COMPUTER                1. MICRO COMPUTER 

                2. DIGITAL COMPUTER                2. MINI COMPUTER 

                3. HYBRID  COMPUTER                3. MAIN COMPUTER 

                                                                              4. SUPER COMPUTER

. BASED ON WORK

.ANALOG COMPUTER

- ANALOG COMPUTER ARE THE JOB -  ORIENTED COMPUTERS.

  THEY CARRY OUT ARITHMETIC AND LOGICALLY OPERATION BY MANIPULATING 

  AND PROCESSING DATA . E.G SPEEDO METER 

  .DIGITAL COMPUTER 

. DIGITAL COMPUTER WORK BY CALCULATING  THE BINARY DIGIT. A DIGITAL COMPUTER , NOT ONLY PERFORMS MATHEMATICAL CALCULATION, BUT ALSO COMBINES THE BYTES  TO PRODUCE DESIRED GRAPHICS, SOUNDS. E.G - DESKTOP (PC)

. HYBRID COMPUTER  

    - HYBRID COMPUTER ARE THE COMBINATION OF ANALOG AND DIGITAL COMPUTERS

      MACHINE USED IN HOSPITAL LIKE ECG AND DIALYSIS ARE THE COMMONLY USED 

      HYBRID COMPUTERS.

. BASED ON SIZE 

. MICRO COMPUTER

 -  MICRO COMPUTER ARE THE LEAST POWERFUL, YET THE MOST WIDELY USED AND 

     FASTER GROWING TYPE OF COMPUTER AND ARE ALSO PORTABLE COMPUTERS.

-   MICRO COMPUTER CONSIST OF THREE BASIC CATEGORIES OF PHYSICAL EQUIPMENT

    , I.E- SYSTEM UNIT ,  INPUT OUTPUT UNIT AND MEMORY UNIT.

. MINI COMPUTER

. MINI COMPUTER ARE SMALLER IN SIZE , FASTER , COST LOWER THAN MAINFRAME

  COMPUTER . INITIALLY THE MINI COMPUTER WAS DESIGNED TO CARRY OUT SOME 

  SPECIFIC TASK , LIKE ENGINEERING AND COMPUTER AIDED DESIGN (CAD)  CALCULATION . BUT NOW , THEY ARE BEING USED AS CENTRAL COMPUTER WHICH 

  IS KNOWN AS SERVER . MINI COMPUTERS ARE IBM-27,  

.MAINFRAME COMPUTER

-  MAINFRAME COMPUTER ARE THOSE HAVING LARGE INTERNAL MEMORY STORAGE 

   AND COMPREHENSIVE RANGE OF SOFTWARE , MAINFRAME COMPUTER SERVER AS

  A BACKBONE FOR THE ENTIRE BUSINESS WORLD. MAINFRAME COMPUTER ARE IBM-

 310, IBM - S\390, UNIVAC-1110 

. SUPER COMPUTER

- SUPER COMPUTER ARE THE FASTEST AND MOST EXPENSIVE MACHINES. THEY HAVE 

  HIGH PROCESSING SPEED COMPARED TO OTHER COMPUTER , SUPER COMPUTER ARE

  USED FOR HIGHLY CALCULATION INTENSIVE TASK, SUCH AS WEATHER FORE 

  CASTING, NUCLEAR RESEARCH, MILITARY AGENCIES AND SCIENTIFIC RESEARCH 

  LABORATORIES.
