The document summarizes the five generations of computers from the 1940s to present. The 1st generation used vacuum tubes for circuitry and punched cards for input/output. The 2nd generation introduced transistors, making computers smaller and more efficient. The 3rd generation saw the development of integrated circuits and magnetic storage. The 4th generation began the era of microprocessors and personal computers. Current 5th generation computers focus on artificial intelligence.

FATHER OF COMPUTERS

The foremost multi-use mechanical computing


machine was most probably Charles Babbage's
"Difference Engine", which got started in 1823
but unfortunately, was not completed.
What is a Computer?

OUTPUT
PROCESS

INPUT

A computer is an electronic machine that can be


programmed to accept data (input), process it into useful
information (output), and store it in a storage device for
future use.

1st Generation (1942 - 1955) : Vacuum Tubes
 Memory was made up of
hundreds of vacuum
tubes or sometimes
magnetic drum.
 Gave off so much heat
that they were cooled by
gigantic air conditioners. IBM Punched Card (input)
 Input and output media
were punched cards and
magnetic tapes.

Magnetic Tapes (output) Vacuum Tubes


UNIVAC 1 ENIAC
2nd Generation (1955 - 1964) : Transistor

 An electronic switch that


alternately allow or disallow
electronic signal to pass, replaces
vacuum tubes.
 These transistors were made of
solid material, some of which is
silicon and cheap to produce .
 Much smaller than vacuum tubes,
draw less power, and generate less
heat, conduct electricity faster.
Walter Brattain John Bardeen

William Shockley
IBM 7070
3rd Generation (1964 - 1975) :Integrated Circuit

 An electronic circuit that packages transistors and other electronic


components into one small silicon chip called semiconductor.
 The number of transistors that is placed on a single chip has increased,
shrinking both the size and cost of computers.
 Keyboards and monitors were used.
 Magnetic disks were used widely as secondary storage .
IBM 360/91
Jack Kilby Robert Noyce
4th Generation (1971-1989) : Microprocessor

 A silicon chip on which transistors are integrated


onto it.

 Microprocessor can do all the processing of a full-


scale computer – smaller in size , faster in speed.

 These circuit integrations are known as Large-scale


integrated (LSI) consists 30,000 electronic
components and Very Large-scale integrated (VLSI)
circuits consists 1 million electronic components.

 Microprocessors led to the invention of personal


computers.
Cray-1 Supercomputer
5th Generation (Present & Beyond)
: Artificial Intelligence

 Artificial Intelligence (AI)


concerns with making computers
behave and think like humans.
 The branch of computer science
that deal with writing computer
programs that can solve problems
creatively.
 AI studies include robotics, games
etc.
