) 4th Generation (1972-2010)
The fourth generation computers started with the invention of microprocessor, as thousands of integrated circuits were built onto a single silicon chip. Ted Hoff produced the first microprocessor in 1971 for Intel. It was known as Intel 4004.The year 1981 IBM Company was designed first computer for home use.1984 saw the Macintosh introduced by Apple. Examples for the fourth generation computers are Apple Macintosh and IBM computers. The size of latest Microprocessors is usually one square inch. It can contain millions of electronic circuits. Latest Microprocessors manufacturing companies are Intel, AMD, and Apple
Fifth generation computing devices, based on artificial intelligence, still scientists are working hard on it. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. They are trying to create a computer with real IQ with the help of advanced programming and technologies. IBM Watson computer is one example for that. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization. The advancement in modern technologies will revolutionize the computer in future.
