FIVE GENERATIONS OF COMPUTER 1_ The Vacuum Tubes 2_Transistors 3_ Integrated Circuits 4_ Microprocessors 5_ Artificial Intelligence The 1st Generation (1940-1956) "The Vacuum Tubes": The 1st Computer, which is created, used "vacuum tubes" as circuitry and the "magnetic drums" as memory, and was often large computer which is equal to the size of an entire room. This computer was very difficult to use and uses a large amount of electricity by which a lot of heat is generated, which causes the chances of errors. This type of computer depends on machine language, the low level programming language which is understood by computer, to perform operation, and they could solve 1 problem at one time only. The given data was based on "punched card" and "paper tapes", and information received was taken as hardcopy. "UNIVAC" and "ENIAC" computer are example of this type of computers. The 2nd Generation (1956-1963) "Transistors": This type of computer uses transistors and replaced the first generation of computer. This type of computer was created in "1947" but, until the late "1950s", did not see wide-spread use in computers. This type was very superior to the first generation, which a ...
