The document discusses the generations of computers from the first to fifth generation. The first generation used vacuum tubes and magnetic drums for memory. The second generation used transistors instead of vacuum tubes, making computers smaller and less heat-generating. The third generation used integrated circuits instead of transistors to make computers even more compact and reliable. The fourth generation used microprocessors and large-scale integrated circuits. The fifth generation is still being developed and focuses on artificial intelligence capabilities like natural language processing.

1. TYPES AND GENERATION OF
COMPUTER

2. CONTENT
 Introduction
 First Generation
 Second Generation
 Third Generation
 Fourth Generation
 Fifth Generation
 Speed

3.  The term Computer Generations is
mainly used to help understand the
various improvement that have taken
place in computer used over last few
decades
Introduction

4. FIRST GENERATION OF
COMPUTER

5. FIRST GENERATION
 First generation of digital computer were
developed in 1940s
 Those computers were built using vacuum
tube and logic circuitry
 They used magnetic drum for main memory
 First generation of computer relied on
machine language , the lowest-level of
programming language understood by
computer
 They could only solve one problem at a time

6. VACUUM TUBES

7.  The speed of first generation computer
were measured in millisecond
SPEED

8. SECOND GENERATION OF
COMPUTER

10. SECOND GENERATION
 Second generation of digital computer
were developed in early 1950s .
 They used transistors in place of
vacuum tubes .
 It was smaller in size , less expensive
and generator less heat than vacuum
tubes
 Even though transistor still generated a
lot of heat which could cause damage to
the computer it was vast improvement
over the vacuum tubes

11. SPEED
 The speed of second generation computer
was measured in micro second.

12. THIRD GENERATION OF COMPUTER

13. INTEGRATED CIRCUITS

14. THIRD GENERATION
 The Third Generation of computer was
developed in the mid 1960s.
 They used Integrated Circuits in place of
transistors.
 Integrated circuits where much more Compact.
 One Integrated circuits could do the Job done
by Hundred transistors.
 The Computer generated less heat and were
more reliable.

15. SPEED
 The Speed of Third generation of computer
was measured in nano-second

17. MICRO-PROCESSORS WERE DEVELOPED IN FOURTH
GENERATION

18. FOURTH GENERATION
 The fourth generation computer were
introduced in 1970s.
 And used last scale integrated (LSI) Circuits.
 LSI Chips can fit on a tip of one finger and
yet they contain thousand of transistor ,
diodes and registers .
 This made it possible for inexpensive micro-
computer to be developed.

19. SPEED
 The fourth generation speed was measured
on pico seconds

23. FIFTH GENERATION
 Fifth Generation computers based on
Artificial Intelligence are still under
development, however there are several
application using voice input that are already
in use today.
 The Goal of fifth generation computing is to
develop devices that respond to natural
language input and are capable of learning
and self organization.

24.  Artificial Intelligence include
 A) Playing game such as Chess ,Where
there has been Considerable success, as the
super computer called Deep Blue could
defeat Gary Kasparov the world chess
champion.
 B) Use of Natural spoken language to
program a computer
