6. Definition of Computer
 Computer is a advance electronic device
that manipulate information/data. It has the
ability to retrieve and process data.
 It can perform Arithmetic and Logical
calculation.

7. 1st Generation
Of Computer

8. 1st Generation Computer
 The first generation computers were from 1940-1956.
 It was made up of Vacuum Tubes which were used for circuitry
and for memory.
 It was expensive to operate.
 It consumed lots of electricity.
 It was bigger in size , it occupied a room space.
 Due to vacuum tubes it generate lot of heat.
 UNIVAC and ENIAC computers are examples of first-generation computing.
 It was developed by two scientists Mauchly and Echert.

9. Limitation Of 1st Generation Computer
 It was large in size.
 It consumed large amount of electricity.
 Operating of computers were costly.
 It’s maintenance was costly.
 It was not portable.

10. 2nd Generation:
The period of second
generation was 1959-1963.The
transition from first generation to
second generation of computers
was not abrupt.

11. Advantages:
Disadvantages:
Smaller in size compared to the first generation of
computer
The second generations computers were more
reliable
Constant maintenance was require
Cooling system was required.

12. 3rd Generation Computers :
The period of third generation
was 1965-1971.

13. Integrated Circuit :
The computers of third generation used
integrated
circuits.
A single IC has many transistors,
resistors and capacitors.
The IC was invented by Jack Kilby .

14. Operating system and languages:
In this generation remote processing,
time-sharing, multiprogramming
operating system were used.
High-level languages
FORTRAN ,COBOL, PASCALPL/1,
BASIC, ALGOL - 68etc,IITOIV.were
used during this generation

15. Main features of third generation:
IC used
Smaller size
Generated less heat
Faster
Lesser maintenance
Still costly
A.C needed
Consumed lesser electricity
Supported high-level language

16. Some computers of this generation:
IBM-360 series
Honeywell-6000 series
PDP Personal Data Processor
IBM-370/168
TDC-316

17. 4th Generation Computers :
The period of fourth
generation was 1971-1980.

18. Microprocessor :
The fourth generation
computers were designed by
using microprocessor, as
thousands of integrated
circuits were built onto a
single silicon chip.

19. Main features of fourth generation:
Some computers of this generation:
Concept of internet was introduced
Great developments in the fields of networks
PDP 11
CRAY-X-MP(Super Computer)

20. 5th Generation Computers :
The period of Fifth
generation was Present
(1980)
-Till date.

21. Operating system:
Windows Linux
Ubuntu Fedora
Mac OS Unix
Languages:
Cobol C++
CC sharp Java
Pascal Prolog
Fortran

22. ULSI Circuit :
In the fifth generation of
computers Ultra Large
Scale Integration circuit
(ULSIs ) began to be
used

23. Main features of Fifth generation:
ULSI used
Smaller size
Artificial Intelligence (AI)
Some computers of this generation:
Desktop
Laptop
Note Book
Ultra Book
Chrome Book
