Today, computers have entered into the various facets of human life. Perkembanganya experienced several phases. Computers we use today is the 4th generation.
The first-generation computers are marked with the creation of Eniac - a large-scale electronic computer, weighing 30 tons, which was completed in 1946. We were able to process the binary aritmetic Eniac, random access, and the concept of stored programs.
Second-generation computer in the year 1959 was marked by the use of transistors, so that the computer is not for the first generation, more save space and cost. Second-generation computers are already capable of processing 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 3rd generation computer works very fast, so it can run a program concurrently (multiprogramming). Generation 4 is the current generation.
In 1981, IBM introduced the use of personal computers (PCs) for use in homes, offices and schools. The number of PCs that 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 continue its evolution toward a smaller size of the computer that is above the desk (desktop computer) to a computer that can be inserted into the bag (laptop), or even a computer that can be grasped (palmtops).
IBM PC to compete with Apple Macintosh computers in the fight over the market. Apple Macintosh became famous, as popularized in computer graphics systems. While competitors are still using text-based computer. Macintosh also popularized the use of mouse devices.
At the present time, we know the way IBM PC compatible with IBM's CPU usage: 486, Pentium, Pentium II, Pentium III, Pentium IV (series of CPUs made by Intel). In addition, we also recognize AMD K6, Athlon, etc.. This is all included in the group's fourth-generation computers.
Along with the proliferation of computer usage in the workplace, new ways to explore the potential to be developed. Along with the increased ability of a small computer, these computers can be connected together in a network to share a memory, software, information, and also to be able to communicate with each other. Computer networks allow computers to form a single electronic cooperation to complete a process task. By using direct cabling (also called local area network, LAN) or telephone cable, the network can become very large.
