Third Generation Computers (Technical Education)

Duration:
The duration of this generation is only about five year i.e. 1964 till 1970.

Development:
In 1969, the first micro processor chip INTEL 4004 was used only in calculator. The famous computer were IBM-360, IBM-370, ONIVAC-9000 series, etc.

Integrated Circuit (IC):
In this generation, integrated circuits were used. AS integrated circuit contains many electronic components on a single chip, result of it could run about 5 million instructions and store upto 8 million characters.

Input / Output And Storage Devices:
There was a big flexibility with input/output and storage devices. The dink oriented systems were made at the end of this generation. The size of computer became very small with better performance and reliability. The faster Input, Output devices made possible multi-processing and multi programming.

Speed:
Computations were performed in nano second.

Supported Language:
High Level Programming language were use.

Application Area:
In this generation, the major applications of computer were used for airline reservations.

Advantages:

  • Smaller in size as compared pervious generations.
  • Reliability increased.
  • Heat generation was rare.
  • Computations were performed in nano seconds.
  • Hardware failure was very rare.
  • Very easy portable.
  • Low maintenance cost.
  • Commercial production was easier and more inexpensive.


Limitations:

  • Air conditioning required in many cases.
