Fourth generation computers were the real type of computer generation which proved that computers can be used for personal life and it's affordable. Fourth generation computers were in the period of 1971-1980. 

Fourth Generation computers got bit user friendly in the size and the design compared with the third generation computers.


Fourth Generation computers adopted the technology from the second and third generation computers and used transistors to a a whole new level.

Fourth Generation computers uses something much similar to ICs or Integrated Circuits, but to make it more efficient, fourth generation computers do use thousands of transistors inside a one silicon layer. Which also can named a silicon chip. Unlike the couple of transistors inside an IC, Thousands of transistors inside a one closed environment is more efficient and cost effective.

The single chip which consist of thousands of transistors got the name as micro processors. Microprocessors does have more pins (probably more than 100) on the surface of the bottom to communicate with the main board or the motherboard to keep processing data.

The inside of the computers got better engineering and designed well to fit in compactly inside. Because of the microprocessor, the computers in fourth generation got more powerful than any other generation lower to fourth generation. 

Fourth generation computers were affordable, compact and reliable due to better engineering inside the computer itself.

There were multiple operating system types introduced and used to make the computing better and efficient.

Due to single point cooling system is implemented and the fourth generation computers uses microprocessors, there were not much cooling required like first generation computers. Because of that reason, the energy usage got lesser and energy wastage got lesser.
