CPU development

1. First Generation
ENIAC (Electrical and Computer Numeric Intregrator) manufactured by IBM in 1945. It is one of the "fathers" huge super computer that size. Just imagine, with a device consisting of 18,000 vacuum tubes, it takes an area of ​​18x8 square meters for its operations clicking! Almost half soccer fields.
The development of the first generation CPU continues with the birth of the EDVAC (Electronic Discrete Variable Automatic Computer) was the first large size computer used for business purposes in the 1951's.

2. Second Generation
Invention of the transistor in 1956 became the beginning of the revolution computer.Transistor replaced vacuum tubes in television, radio, and computers so that the size to be much smaller than sebelumnya.Transistor also create demand for electricity will be lower.
In this period became known programing.With language programming languages, computer started easily understood by many people because the term used to enter data no longer figures - binary numbers but has the form of text.
At this time, the computer more and more used for business purposes because this object has been able to perform the function - the function of a business transaction.

3. Third Generation
Found IC (Integrated Circuit) by Jack Kilby in 1960 became a milestone marker of the computer revolution, particularly the CPU.IC compensate for the shortcomings posed by the use of transistors on a CPU that makes a computer device quickly hot.
Although in many respects, the transistors outperform the vacuum tube, but transistors generate heat consumption is large enough to potentially damaging parts - the inside of the computer.
Quartz stone managed to overcome this problem. IC combined three electronic components in a small silicon disc made of sand power. then the scientists managed to condense a lot of CPU components into a single chip, called a semiconductor.
The discovery of the operating system as part of the software has also become an important marker of this generation.

4. Fourth Generation
Chip maker Intel 4004 in 1971 by Intel brought significant progress for the development of CPU. It was then that the incorporation of the various components of the previously separate CPU on the device becomes a reality. Components - components such as memory, bus, and the processor can be put together in just one small chip devices.
Computers are no longer as big as a football field or the size of the building and rooms. computers became much more mini. then in the early 1970s, computers began to be produced for all people, not just limited to big businesses.
If the previous CPU in a computer separate from the screen, laptop discovery in the early 1990s to change the paradigm that computer must be on the spot again tertentu.Apa that time the human need for a computer device that is easy to carry everywhere began meningkat.maka invention of laptops become very menggembirakan.Saat news that is integrated with the CPU start screen. The era of globalization is characterized by the revolution in the early 1990.Paradigma onternet human against computer objects more flexible again. thanks to Internet technology that allows various access to information, people increasingly want to travel around the world.
A growing trend hereinafter that the merging of the CPU with monitor, known as the Ipad tablet PC.contohnya is.
