Generations of Computer

FIRST GENERATION

Introduction:
1946-1959 is the period of first generation computer.
J.P.Eckert and J.W.Mauchy invented the first successful electronic computer called ENIAC, ENIAC stands for “Electronic Numeric Integrated And Calculator”.
Few Examples are:
ENIAC
EDVAC
UNIVAC
IBM-701
IBM-650

SECOND GENERATION

Introduction:
1959-1965 is the period of second-generation computer.
Second generation computers were based on Transistor instead of vacuum tubes.
Few Examples are:
Honeywell 400
IBM 7094
CDC 1604
CDC 3600
UNIVAC 1108

THIRD GENERATION

Introduction:
1965-1971 is the period of third generation computer.
These computers were based on Integrated circuits.
IC was invented by Robert Noyce and Jack Kilby In 1958-1959.
IC was a single component containing number of transistors.
Few Examples are:
PDP-8
PDP-11
ICL 2900
IBM 360
IBM 370


FOURTH GENERATION

Introduction:
1971-1980 is the period of fourth generation computer.
This technology is based on Microprocessor.
A microprocessor is used in a computer for any logical and arithmetic function to be performed in any program.
Graphics User Interface (GUI) technology was exploited to offer more comfort to users.
Few Examples are:
IBM 4341
DEC 10
STAR 1000
PUP 11

FIFTH GENERATION
Introduction:
The period of the fifth generation in 1980-onwards.
This generation is based on artificial intelligence.
The aim of the fifth generation is to make a device which could respond to natural language input and are capable of learning and self-organization.
This generation is based on ULSI(Ultra Large Scale Integration) technology resulting in the production of microprocessor chips having ten million electronic component.
Few Examples are:
Desktop
Laptop
NoteBook
UltraBook
Chromebook
