2. GENERATION OF COMPUTER
MEANS IMPROVEMENT IN THE
FIELD OF COMPUTER .
What is generation of
computer ?

3. Types of generation
of computers
 There are 5 types of generation of
computers :
 First generation
 Second generation
 Third generation
 Fourth generation
 Fifth generation

4. First generation {1940 –
1956}
 First generation of computers used vaccum
tubes for circuitry and magnetic drums for
memory . It uses machine language .
 Eg. Univac & enaic computers

5. Disadvantage of 1 generation
computers
 They were very large and often takes 1
room .
 They were very expensive .
 They uses a large amount of electricity
&generate a lot of heat .

6. Second generation {1956 –
1963}
 They were invented in 1947 but not see
widespread in computers until 1950 .
Transistors were used as the second
generation computers .
 In this type of generation computers uses
binary machine language or assembly
language .

7. Advantage of 2 generation
computers
 The transistors were superior for vaccum
tubes allowing computers to be more
faster , cheaper , smaller , etc .
 These computers for atomic energy
industry .

8. Third generation {
1964 -1971 } The integrated circuits was the hallmark
of 3 generation computers .

9. Advantage of 3 generation computers
 By the help of integrated circuits transistors
were miniaturised & placed on silicon chips
called semicondors which increases speed &
efficiency of computers .
 Instead of punch cards it uses keyboards
,monitors & interfaced with an operating system
.

10. fourth generation {1971 -
present } The microprocessor was the
fourth generation computers .
 The microprocessor is just like as
thousands of integrated circuits
(3 generation computer ) built onto
a single microchip

11. Advantage of 4 Generation
computers Because of 4 generation more & more
every products begin to use
microprocessors .
 Because of 4 generation computer we
used to saw development of GUI’s
the mouse , & handheld devices .

12. Fifth generation { Present &
Beyond } This generation of computer is the
most advance & the best generation
of computer till now .This
generation is based on artificial
intelligence

13. Advantage of fifth generation of
computers
 Because of artificial intelligence the
computer will solve all the equation in
nanosecond .
 The use of parallel processing &
superconductors of this generation is
helping to make artificial intelligence a
reality .
