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 .
