The first generation computers are marked with the creation of Eniac - a large-scale electronic computer, weighing 30 tons, which finished in 1946. When it Eniac aritmetic capable of processing binary, random access, and the concept of stored programs.
Computer generation 2 in 1959 was marked by the use of transistors, so that the computer is not for the first generation, more mengirit space and cost. Computer-2 generation has been able to process low-level programming.
3rd Generation in the year 1964 was marked when IBM launched the computer system 360 on 7 April 1964. At the time, the computer-generation to 3 working very fast, so that one program can run concurrently (multiprogramming). Generation to generation-4 is present.
In 1981, IBM introduced its personal computer (PC) for use in homes, offices, and schools. The number of PCs in use jumped from 2 million units in 1981 to 5.5 million units in 1982. Ten years later, 65 million PCs have been used.
Computers continued evolution towards smaller size of the computer that was on the table (desktop computers) into a computer that can be inserted into the bag (laptop), or even a handheld computer that can (palmtops).
IBM PC to compete with Apple Macintosh computers in the market fighting. Apple Macintosh became famous, because it popularized in computer graphics systems. While competitors are still using a text-based computer. Macintosh also popularized the use of mouse devices.
At the present time, we know the way IBM compatible with IBM PC CPU usage: 486, pentium, pentium II, pentium III, Pentium IV (series of CPUs made by Intel). In addition, we also know k6 AMD, Athlon, etc.. This is all included in the computer classes to the 4th generation.
Along with the proliferation of computer usage in the workplace, new ways to explore the potential being developed. Along with the increased ability of a small computer, these computers can be connected together in a network for memory sharing, software, information, and also to communicate with each other. Computer networks allow computers to form a single electronic collaboration to complete an assignment process. By using direct cabling (also called local area network, LAN) or telephone cable, the network can become very large.
