Cohort of the Computers

Just like “Homo sapiens”, computers have their generations too. Computers evolved the way how people evolve too. Homo sapiens evolve very fast. On the other hand, computers also transform.  Computers started as a very very enormous apparatus. Very big that can occupy two rooms. From 1940-1956, “Vacuum Tubes” are used to store binary. One vacuum tube can store on binary. Computation time was in millisecond and Inputs are through Punched Cards and Paper Tapes. Then the “Transistors” came on 1956-1963. During this time, magnetic core technology is used for primary memory. Instructions were written in assembly language. Just like the first generation, computation time was also in milliseconds. Leading the time of 1964-1971were the Integrated Circuits. Multiple transistors were place on a silicon chip. High-level languages were used instead of the assembly and machine language and also, computation time was in nanoseconds. From 1971 to the time present, “microprocessors” are used. This supported Graphical-Used Interface (GUI), developed MS-DOS and MS-Windows. Unlike the three generations at the past, computation time was in picoseconds.
