Computer Generations And speed Details

The first computers which were made used the Magnetic Drums and they were very large in their size. Eventually the size of the computers reduced and their reliability and speed also increased. This was possible due to the advent of new technologies which made it possible to make the circuits in small area and those which made it possible to draw more sophisticated circuits which were more efficient and reliable in a very small size. With the advent of semi conductor chips the size of the computers were reduced enormously and their efficiency and speed were also increased. Their capacity to process data at a time increased and they become more compact in size. With the advancement of technology and introduction to the Ultra large scale Integrated circuits computer adapted for fuzzy logics and artificial intelligence which gave them the power to think.Computer Generations and speed of Computer development.

You can now play the game of chess with the computer and computer can recognize your entire move and based on the algorithm and fuzzy logic it can defeat you easily. This has made the computers more intelligence and yet a lot of improvements can be still made in the computers.

Earlier the computer required the air conditioning due to its large size and it generated a very large amount of heat but consequently it was improved.
