Computers are made from components that perform simple clean-cut functions. The complex interactions of these components give computers the ability to process information. If correctly assemble, a computer can be made to represent some aspect of a problem or part of a system. If a computer is configured in this way is given input data, then it can automatically solve the problem or predict the behavior of the system.1 General principlesComputers can work through the movement of mechanical parts, electrons, photons, quantum particles or any(prenominal) other well-understood physical phenomenon. Although computers pass water been built out of many assorted technologies, nearly all popular types of computers have electronic components.Computers may flat model the problem existence solved, i n the sense that the problem creation solved is mapped as closely as possible onto the physical phenomena being exploited. For example, electron flows might be used to model the flow of body of water in a dam. Such analog computers were once common in the 1960s but are now rare. They are practically dead.In intimately computers today, the problem is first translated into mathematical terms by r... ...this clock sharing. Newer generations of CPUs really uses HT-technologie (e.g. Intel processors). But there are likewise processors with more than one processing unit on it. AMD calls them dual-core processors.6.7.1 Operating systemWhen a computer is running it needs a program, whether or not there is useful work to do. In a typical setting computer, this program is the operating system (OS). The operating system decides which programs are run, when, and what resources (such as memory or input/output - I/O) the programs will get out to use.The operating system also provides a layer of abstraction all over the ironware, and gives access by providing services to other programs, such as encipher (drivers) which allow programmers to write programs for a machine without needing to know the intimate expound of all the attached electronic devices.Most operating systems that have hardware abstraction layers also provide a standardized user interface. The most popular OS remains the Windows family of operating systems.Most computers are very small, very inexpensive computers embedded in other machinery. These embedded systems have programs, but often lack a recognizable operating system.
