The main advantage of using an operating system is that it enables users to run their own computer without any knowledge of coding. Without an operating system, your hardware would not work at all, until you wrote your own code for the hardware telling it what to do.
An operating system (OS) is software, consisting of programs and data that runs on computers, managing computer hardware resources and providing services for various application software.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between application programs and the computer hardware, although the application code is usually executed directly by the hardware and will frequently call the OS or be interrupted by it. Operating systems are found on almost any device that contains a computer; from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems are: BSD, Linux, Mac OS X, Microsoft Windows and UNIX
An operating system consists of many parts. One of the most important components is the kernel, which controls low-level processes that the average user usually cannot see; it controls how memory is read and written, the order in which processes are executed, how information is received and sent by devices like the monitor, keyboard and mouse and decides how to interpret information received from networks. The user interface is a component that interacts with the computer user directly, allowing them to control and use programs. The user interface may be graphical with icons and a desktop or textual, with a command line. Application programming interfaces provide services and code libraries that let application developers write modular codes, reusing well defined programming sequences in user space libraries or in the operating system itself.
