In a computer system it is the software, which is the brains of the enterprise. Some people maintain that the microprocessor is the brain of the computer. No. No. No. No. No. The microprocessor is fair a large, flat, expensive piece of technology - like a Keebler Fudgekuchen with the metal legs. They need software to let the microprocessor seem how it has each possible kind of intelligence. The operating system the main piece of software your computer steering is the operating system. The operating system - not the microprocessor - explains the complete computer which to do. All small articles, including the microprocessor, must obey the operating system. And, all software must work with the operating system. The operating system has three important jobs: if you steer the small articles, steer the software and you give you (humans) a way to finally steer everything. Steer these small articles! The operating system explains the computer which to do and as to it does they although the microprocessor within the computer the work settle can, gives the operating system the orders. Near connected with the operating system the chip set (you see the section "the Motherboard," early in this chapter). The operating system gives instructions, in the process of its tasks, to the microprocessor and to the chip set. Supervise this software!
The whole software, you (everything - all applications, programs, utility programs and plays) must with the operating system work to use. Software for the operating system is actually written, not for the computer or the microprocessor (only some plays are written directly to the computer hardware. Straight one over every other program is intended for a specific operating system) the key to a successful operating system is a large software lower surface, which means lots of computer programs, which work under this operating system. That lower surface is, which so successfully forms the traditional operating systems. Although each DOS hated, it could let programs run million.

That is, which formed it so popular (although infamously so). Work with humans! Finally the operating system you, the person must finally represents responsible for the computer, with an appropriate method of steering of things. Most operating systems use a graphic interface, to which appearance represents you and pictures, in order to represent computer concepts. The operating system must you ways to let programs run and show ways to steer the computer hardware. Chapter 15 discusses different kinds of operating system in the detail and shows you, why some operating systems settle this locking work better than others. The operating system and the microprocessor must work together, in order to give you the optimum computer. If they work together, they are said, in order to be compatible. They are probable to use only one operating system. Some computers can having more than, but a layer adds complexity using the computer that I think that you would avoid rather. Even brief case computers and play consoles have operating systems. They cannot be so complicated like an operating system of the desk calculator, but the operating system is there nontheless.
