different types of computers

this ppt explains various types of computer ..

1. Classification of computer by function Classification of computer by size & capacity Classification of computer by speed analog digital hybrid Super computer Mainframe computer Mini computer Micro computer Desktop computer Pocket computer

2. Classification Of Computer By Function Analog computer The computers in which data varies continuously i.e., the movement of data is continuous . Ex: Thermometer,  Analog clock,  Speedometer  

3. b) Digital computer The computer in which data flows in discrete form (by parts). Ex: digital watch c) Hybrid computer Combination of analog and digital computer. Ex: air pressure, PC

4. 2. Classification of computer by size & capacity Super computer Super computer handles complex scientific and statistical applications or programs. High speed, high capacity memory but non-portable as size is very large. Ex: railway reservation, weather forecasting. b) Mainframe computer Smaller when compared to super computer. Memory capacity high but non- portable.

5. c) Mini computer: processing speed is slower than super and mainframe computers. These are portable. d) Micro computer: smaller than mini computer. High speed but slower than mini computer. e) Desktop computer: used in education system & small scale industry. Home computers, portable, high speed. d) Pocket computer: very small in size. portable but memory capacity is less.

6. 3. Classification of computer by speed Different processors have different processing speed Examples: X86 8086 & 8088 Pentium Pentium II Celeron Xeon
