1st generation started
The period of first generation was 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU (Central Processing Unit). These tubes, like electric bulbs, produced a lot of heat and were prone to frequent fusing of the installations, therefore, were very expensive and could be afforded only by very large organisations. In this generation mainly batch processing operating system were used. -
starts the 2nd generation
The period of second generation was 1959-1965. In this generation transistors were used that were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes. In this generation, magnetic cores were used as primary memory and magnetic tape and magnetic disks as secondary storage devices. In this generation assembly language and high-level programming languages like FORTRAN, COBOL were used. -
begins the 3rd generation
The period of third generation was from 1964 to 1971. Integrated circuits (IC's) are used in third generation computers. The integrated circuit was invented by Jack Kilby and Robert Noyce.
The electronic circuit formed by constructing electronic components like transistor, resistor and capacitor on a small piece of semiconducting material is called integrated circuit. Integrated circuit is also called as chip or microchip. Large number of transistors is placed on a single chip. -
starts the 4th generation
The period of fourth generation was 1971-1980. The computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements and their associated circuits on a single chip made it possible to have microcomputers of fourth generation. Fourth generation computers became more powerful, compact, reliable, and affordable. As a result, it gave rise to personal computer (PC) revolution. -
starts the 5th generation
The period of fifth generation is 1980-till date. In 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. AI is an emerging branch in computer science, which interprets means and method of making computers think like human beings. -
the begining of the 6th generation
The sixth generation of computer differs from previous generations in terms of size, processing speed and the complexity of tasks that computers can now perform. Back in the earliest stages of computing, computers contained vacuum tubes and magnetic drums. They were large, expensive and could only perform one task at a time. It includes artificial intelligence, tha make easlyer the programation of computers to adapt and join them to our live
