IT Development Computers Digital Generation begins when beings. The first generation of existence in the year 1951-1958. Tiub vacuum when it is used as the main element of logic. Inputs to the computer using the perforation and the data stored by using storan surface. in the well using a magnetic drum. to be written in machine language and the collective.





The second generation (1959-1963) was replaced with vacuum tiub transistors as main logic element. Magnetic tape and also has cakera kat perforation and act as surface storan equipment. setting the language used to create high as FORTRAN and Cobol.



Transistor circuits have also been replaced with bersepadu in the era of Third Generation (1964-1979). Magnetic tape and replace KAD cakera full perforation and memory conductor metal oxide (MOS) was introduced. High language has been built, such as BASIC.



Fourth generation of computers such as today's use of scale circuits (LSI and VLSI). Microprocessor circuits contain memory, logic and the introduction of a CIP. The first personal computer introduced by Apple (1984) and IBM (1981) for use at home. MS-DOS operating system used widely. Fourth generation language settings are built, such as Visual C + + and Visual Basic characteristics of the user's face.
