Generation of Computers Created by Priya Soni 30/11/2011
Generation of Computers Computers can be classified into five types according to the generations i.e. time period: First Generation Computers Second Generation Computers Third Generation Computers Fourth Generation Computers Fifth Generation Computers
First Generation Computers Period: 1946-54 Size was equivalent to a room Machine and Assembly language Vacuum Tubes Punched cards & paper tape Magnetic drum & Magnetic tape Size: Language: Main Component: Input/output Media: Storage Media:
First Generation Computer Advantages : . It was only electronic device . First device to hold memory Disadvantages : . Too bulky i.e. large in size . Vacuum tubes burn frequently . They were producing heat . Maintenance problems
Second Generation Computers Period: 1955-64 Smaller than 1st generation Assembly & high level language Transistors Punched cards & printed Size: Language: Main Component: Input/output Media: reports Storage Media: Magnetic tape & magnetic disk
Second Generation Computer Advantages : . Size reduced considerably . The very fast . Very much reliable Disadvantages : . They over heated quickly . Maintenance problems
Third Generation Computers Period: 1965-74 Disk size mini computers High level language ICs (Integrated Circuits) Key to tape, key to disk & printed reports Magnetic tape & magnetic disk Size: Language: Main Component: Input/output Media: Storage Media:
Third Generation Computer Advantages : . ICs are very small in size . Improved performance . Production cost cheap Disadvantages : . ICs are sophisticated
Fourth Generation Computers Period: 1975-89 Typewriter size micro computers High level language ICs with LSI (Large Scale Integration) Keyboard data entry, input devices & printed reports Magnetic disk, floppy & optical disk Size: Language: Main Component: Input/output Media: Storage Media:
ICs with LSI (Large Scale Integration)
Fourth Generation Computer Advantages : . It is a compact . Less power consumption . Production cost is cheap Disadvantages : . No artificial intelligent.
Fifth Generation Computers Period: 1990 s- present & beyond Credit card size micro computers Artificial intelligence language SLSI/ULSI (Super/Ultra Large Scale Integration) Tactile inputs, displays Optical disk & card magnetic disk Size: Language: Main Component: Input/output Media: Storage Media:
Fifth Generation Computer Advantages : . Artificial intelligence . Expert system . Very low cost
. First generation computer Vacuum tubes . Second generation computer Transistors . Third generation computer ICs . Fourth generation computer ICs with VLSI . Fifth generation computer ICs with parallel processing
