Everyone knows that computer plays a very important role of human's life. Computer almost covered all te areas. We use computer to count, to talk, to write, to manage a factory...
Technology develops when human beings want to make convenience and advantage for their life. The computer history begin with the countting. During the accient time Chinese were becoming very involved in commerce with the Japanese, Indian, and Koreans. they needed a way to accounts and bills, thus the first account tool was born - the abacus. The second step of moving computational technology along was the invention of simple mechanical scale for weighing and measuring. In the 17th century, John Napier, Baron of Merchiston, Scotland, invened logrithms which was a big advances in computation. In te same centure, German mathematician Wilhel Schickard built one of the first mechanical calculator which use the system of cogs and gears. Duing the 19th century, the mathematician and inventor Charles Babbage first worked out a device to undertake mechanical calculus, which noticed as the different engine.After the convergence of the development of calculation, and the need of the war, Alan Turing and some mathematicians and cryptographers the devised the first working computer which was used to break secret German 'Enigma' codes.

After the Second World War, computer had a significant improvement in USA. I n 1950s, IBM first produced the commercial computer. The first generation computers were large and expensive machines for military, government. But in 1965, they were quickly became apparent that computers would get smaller, quicker and less expensive at an exponential rate. Xerox PARC developed concepts such as the mouse, the graphical user interface (GUI) and pull-down menus that made the personal computers of today possible and approachable by the general user. Afterwards computor moved out of the laboratories and military and be used widely in he office, home and classroom. Microsoft of Bill Gates is the most famouse development of computer that made a lot of covenience to the world.
Nowadays, it is very hard for people to work or study without computor. It is very necessary for us to think about whether computers will control us in the future.
