The fourth generation computers began with the innovation of microchip, as thousands of integrated circuits was constructed onto a solitary silicon chip. Ted Hoff created the main chip in 1971 for Intel. It was known as Intel 4004.The year 1981 IBM Company was designed first PC for home use.1984 saw the Macintosh presented by Apple. Cases for the fourth generation computers are Apple Macintosh and IBM computers. The span of most recent Microprocessors is generally one square inch. It can contain a large number of electronic circuits. Most recent Microprocessors manufacturing companies are Intel, AMD, and Apple.
Fifth generation computing devices, based on artificial intelligence, still researchers are working hard on it. The utilization of parallel preparing and superconductors is making artificial intelligence a reality. They are endeavoring to make a computer with genuine IQ with the assistance of cutting edge programming and innovations. IBM Watson computer is one case for that. The objective of fifth-generation figuring is to create devices that react to natural language input and are fit for learning and self-association. The progression in present day advancements will revolutionize the PC in future.
The computers that we use present days belonged to the 4th generation computers. We can classify these computers following types.
