The computer that we use today is as a result of the ingenuity point calculation tool, which has a long and evolving. Starting from the initial calculation tool is the "lukkhit" (Abacus) created in China. Approximately 2000-3000 years ago.Until 2376 (1833) British mathematician named Charles a beige (Charles Babbage). the invention machine analysis (Analytical Engine) can calculate the values of the trigonometric functions math. This work is divided into 3 sections, the section is calculated and the cockpit. The system is used to power steam engines rotate the gear teeth. Contains information on punch cards. Automatically calculate and store information in memory before they are printed on paper.The principle of this beige has brought new development of modern computers, we honored the father's beige computer.Since then, there have been a lot more computer artificial intelligence many size. It is the start of a true computer era can be divided into 5 computer era.Era one (First Generation Computer) 2489 (1946)-2501.As the invention of the computer, not a calculator by mao Lee and Executive khoet (Eckert and Mauchly) has introduced the concept of the invention is a very powerful computer, one called the ENIAC (Electronic Numericial Integrator and Calculator), which later were made to improve the operation of the computer, better efficiency and devise a UNIVAC (Universal Automatic Computer) up to the annual demographic survey.Thus the UNIVAC is the world's first computer is being used for commercial business, which is the start of the computer era, the first truly. In this age of computer controlled vacuum tube computer, which work more quickly, but it is very large and expensive. The first generation of computer end whenever there is a vacuum tube transistor fabricated using.The identity of the computer era 1Use vacuum tube devices. (Vacuum Tube) is the main component in a larger machine. Electric power and heatWork machine (Machine Language) only.Starting with the development of sign language (Symbolic Assembly Language/), up available.
