operating system

Operating system is the program, which usually installed into the computer by a boot program. It manages all other programs in computer. Sometimes it also called as "OS". These programs also called applications. The application uses the operating system by making requests for services through API (Application Program Interface). Sometimes users can directly use the operating system through GUI (Graphical Users Interface) or command language. Operating system is a program that allows you to work with hardware and software on your computer. Basically, there are two ways to use operating system on your computer.

Macintosh computers are loaded with Mac OS. Many computers or servers use the Linux or UNIX operating system. The operating system is the first thing loaded on the computer- without operating system (OS) the computer is useless and we can't do any functions on it. Now at the moment, operating systems have started to use OS in small computers as well. If we mess with electronic devices, we can see the operating system in many of the devices, which we use every day, from mobile phone to wireless access points. The computer use in these little devices is more powerful and they can easily run operating system and applications of it.

The main aim of the operating system is to organize and control the hardware and software so that the device behaves in a flexible way. All computers does not having operating systems, for ex - the computer that controls the microwave oven in your kitchen, does not need operating system to work because it has only one set of job to do. The most common window operating systems developed by Microsoft. There are other hundreds of other operating system available for special-purpose applications, including manufacturing, robotics, and mainframes and so on.
