Based on the characteristics of various computers developed from time to time,
they are categorized as generation of computers.
The Computers in this generation used machine code as the programming language.
-The main feature of the first generation
. vacuum tube technology
. Unreliable
.Supported machine language only
.Very costly
.Generated a lot of heat
.Slow input and out devices
.Huge size
.Need of AC
.Non-portable
.Consumed a lot of electricity
*Some of the example of generation.
.ENTAC,
.EDVAC,
.UNIVAC,
.IBM-701,
-The main feature this second generation
.Use of trangisters
.Reliable in comparison to first generation computers
.Smaller size as compared to first generation computers.
.Generated less heat as compared to first generation computer.
.Faster then first generation computers
.Still very costly
.Supported machine and assembly language
*Some of the example this generation.
.IBM 1620,
.IBM7094,
.CDC 1604,
UNIVAC 1108,
-The main feature of the third generation
The IC was invented by Jack killby. This development made computer smaller in size , reliable , and efficient
in this generation remote processing , time-sharing , multiprogramming operating system were used high
level languages .
*Some of the example this generation.
.FORTRAN-II TO IV ,
.COBOL ,
.PASCAL PL/I ,
.BASIC ,
.ALGOL-68
feature this generation
.IC used (Integrated Circuit)
.More reliable in comparison to previous two generations.
.Smaller size
.Generated less heat
.Faster
.Lasse maintenance
.Costly
.AC required
.Supported high -level language
*Some of the example this generation.
.IBM-360 series,
.Honeywell-600 series,
.PDP (Personal Data Processor)
.IBM-370/168
-The main feature this fourth generation
Fourth generation computers become more powerful , compact , reliable,
and affordable. As a result, it gave rise to personal computer(pc) revolution .
In this generation , time sharing , real time network , distributed operating system were
used . All the high - level language like C, C++ ,DBASE etc.,
were use in this generation,
*Some of the example this generation.
.VLSI technology used
.Very cheap
.proable and reliable
.Use of pcs
.very small size
.Pipeline processing
.No AC required
-The main feature of the fifth generation
This generation is based pm parallel processing hardware and AI (Artificial Intelligence ) Software .
AI is an emerging branch in Computer Science , which interprets the means and method of making computers think like human being All the high - level language like C and C++ JAVA NET etc.. are used in this generation.
*Some of the example this generation.
