A Short description about the generation of computer

1. -Palash Ratner

2.  Used vacuum tubes for circuitry and
magnetic drums for memory
 Size were often enormous, taking up
entire rooms and very expensive
 First generation computers relied on
machine language, the lowest-level
programming language
 Input was based on punched cards and
paper tape, and output was displayed
on printouts
 UNIVAC and ENIAC computers are
examples of this generation

3.  Transistors replaced vacuum
tubes for circuitry and magnetic
drums by magnetic core
technology for memory in this
generation
 Smaller, faster, and more reliable
 Second-generation computers
moved to symbolic, or assembly,
languages, COBOL and
FORTRAN are also developed at
these times.
 Second-generation computers
still relied on punched cards for
input and printouts for output.
 IBM 7094, CDC 3600 computers
are examples of this generation

4.  IC (Integrated Circuit) are used for
circuitry which drastically increased
the speed and efficiency of computers.
 The development of Third Generation
Computers resulted end of the usage of
first and second generation computers.
 These 3rd Generation Computer
generate less heat then its
predecessors.
 users interacted with third generation
computers through keyboards and
monitors
 Computers for the first time became
accessible to a public.
 Floppy Drive (80kb) Came into picture
invented by IBM Eg. PDP-8 , CDC 6600

5.  The microprocessor brought the
fourth generation of computers .
 What in the first generation filled
an entire room could now fit in the
palm of the hand and lot cheaper
 smaller, faster, more reliable, and
lower in price
 Size of a television or much
smaller
 Can do 500,000 to 1,000,000,000
operations/second
 Cost one-tenth, or less, the
amount of third generation
 very common in homes and
business
 Eg Apple , Dell Alienware, Dell
inspiron ,etc…

6.  These generation will be thinking
machines .
 Fifth generation computing
devices, based on artificial
intelligence, are still in
development
 The goal of fifth-generation
computing is to develop devices
that respond to natural language
input and are capable of learning
and self-organization though
there are some applications, such
as voice recognition.
 Quantum computation and
molecular and nanotechnology
will radically change the face of
computers in years to come.
