First Generation Of Computers (1940-1950)
- In this computer used vacuum tube.
- Machinery language added in this computer.
- Consume a lot of electricity.
- Very slow and very large in size.
- Used punched cards and paper tape.
- There were about 100 different vacuum tube computers produced between 1942 and1963.
Second Generation Of Computers (1950-1960)
- Used magnetic core and tapes.
- Assembly language used.
- Generated less heat.
- Improve the speed this computer.
- Used punched cards.
- Examples IBM 1401, IBM 7090 and 7094, UNIVAC 1107 etc.
Third Generation Of Computers (1960-1970)
- Use a integrated circuits (ICs).
- High level language (FORTRAN, BASIC, Pascal, COBOL, C, etc.)
- Improve the speed.
- Used output devices like monitor, printer, etc.
- Examples like IBM 360, IBM 370, PDP-11etc.
Fourth Generation Of Computers (1970-present)
- Used (VLSI) and microprocessor.
- Used RAM, ROM.
- Fourth generation is better than third.
- In this computer speed is very nice.
- Used both devices input and output like mouse,printer,scanner etc..
Fifth Generation Of Computers (the present and the future)
Main electronic component: based on artificial intelligence, uses the Ultra Large-Scale Integration (ULSI) technology and parallel processing method
- Language – understand natural language (human language).
- Power – consume less power and less heat.
- Speed – remarkable improvement of speed, accuracy and reliability (in comparison with the fourth generation computers).
- Size – portable and small in size, and have a huge storage capacity.
- Input / output device – keyboard, monitor, mouse, trackpad (or touchpad), touchscreen, pen, speech input (recognise voice / speech), light scanner, printer, etc.
