Here again we will discuss about fourth generation of computer. The time period of 4th generation of computer was ( 1971 - 1980 ). It contains very large scale integrated ( VLSI) circuits. VLSI circuit having 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of 4th generations. Fourth generation computers became more powerful compact, reliable, and affordable. It also give rise to personal computer revolution . In this generation time sharing , real time networs , distributed operating system were used. All the high level language skills like C, C++, DATABASE etc were used in this generation. It bring great development in the field of network aswellas computers became easliy available. Maintenance costs wass lesser than the last generations.
the fifth generation, the VLSI technology became ULSI (Ultra Large Scale Integration) technology, resulting in the production of microprocessor chips having ten million electronic components. This generation is based on parallel processing hardware and AI (Artificial Intelligence) software. AL is an emerging branch in computer science which interprets the mean and method of making computer think like human beings. All the heigh level language like c, c++, java, . Net etc are used in this generation. It is a type of robotics and having neural network game playing. Development of expert system to make decisions in real life situations.
