The Computer (engl. computer evaluator ) machine for undertaking the calculations. At calculations computer capable to process information on beforehand determined algorithm. Besides, majority computer capable to save information and realize information retrieval, remove information on different types device issues to information. Its name computers has got on its main function undertaking the calculations. However at present suppose that main function computer information handling and management.

The Cardinal principles: Execution put(deliver)ed before him problems computer can provide when displacement of some mechanical parts, motion flow electron, photon, quantum particles or for count of the use effect from any other well studied physical phenomenas.

The Most spreading amongst computer have got so named electronic-computing
machines , COMPUTER. Strictly, for suppressing majority of the people, word electronic-computing machines and computers become word synonym though indeed this not so. The most wide-spread type computer electronic personal computer.

The Architecture computer can directly prototype solved a problem, greatly close (in the sense of mathematical description) reflecting under investigation physical phenomenas. So, electronic flows can be used as models flow water at modeling of the dams or dams. Such a image constructed analog computers were usual in 60-h year XX age, however today become it is enough rare phenomena.

In majority modern computer problem is first described in mathematical term, herewith whole необходимая information introduces in binary form (in the manner of units and zeroes) whereupon actions on her(its) processing are reduced to using algebra idle time logic. Since practically whole mathematics can be сведена to execution boolean operation, it is enough quick electronic computer can be shall use for decision majority mathematical problems (as well as majority of the problems on information handling, which can be easy сведены to mathematical).

It Was discovered that computers even so can solve not any mathematical problem. For the first time problems, which can be not solved at computer, were described english by mathematician Alanom Tiyuringom.

Result of the executed task can be represented user with the help of different device of the entering-output to information, such, as lamp indicators, monitors, printers and t. p.

The Beginning users and particularly children often by a narrow margin perceive the idea that computer simply machine and can not by itself think or understand that word, which he shows. The Computer only mechanically displays the givenned program to lines and colour at device of the entering-output. The Human brain itself will acknowledge in expressed on screen images, numbers or word and will add him that or other importances.
