Computers are made from components that perform simple well-defined functions. The complex interactions of these components hold in computers the ability to process information. If correctly configured, a computer can be made to represent some aspect of a caper or part of a system. If a computer is configured in this agency is given input data, then it can automatically solve the hassle or predict the behavior of the system.1 General principlesComputers can work through the movement of mechanical parts, electrons, photons, quantum particles or any other well-understood fleshly phenomenon. Although computers have been built out of many different technologies, nearly all popular types of computers have electronic components.Computers may directly model the ta sk being solved, in the sense that the problem being solved is mapped as closely as possible onto the physical phenomena being exploited. For example, electron flows capacity be used to model the flow of water in a dam. Such analog computers were once common in the 1960s merely are now rare. They are practically dead.In most computers today, the problem is first translated into mathematical terms by r... ...this time sharing. Newer generations of CPUs really uses HT-technologie (e.g. Intel processors). But there are as well as 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 profitable work to do. In a typical desktop computer, this program is the operate 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 to use.The operating system also provi des a layer of abstraction over the hardware, and gives access by providing services to other programs, such as code (drivers) which allow programmers to lay aside programs for a machine without needing to know the intimate details of all the attach 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 crummy computers embedded in other machinery. These embedded systems have programs, but very much lack a recognizable operating system.
