The Five Generations Of Computers Covered In a Gist!!!
The first generation (1940- 1956) computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
The Second Generation (1956-1963) transistors are replaced by vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s.
The third generation (1964-1971) integrated circuit is the development of the integrated circuit was the hallmark of the third generation of computers.
The fourth generation (1971 - Present) comprises of the Microprocessors. In this generation, thousands of integrated circuits were built onto a single silicon chip.
The fifth generation (present and beyond) artificial intelligence are still in development though there are some applications such as voice recognition that are used today.
