Operating system (usually abbreviated to the OS, O / S or kernel) is an interface between hardware and software in computer systems. OS is responsible for managing and coordinating activities and sharing of limited resources of the computer. Operating system that acts as host for applications that run on the computer. As the host, the main purpose of the operating system is to handle the details of hardware operation. This frees the application program to manage low-level hardware and makes it easier to write software. Almost all computers, including laptops, desktop computers, supercomputer, and even video game consoles, using the operating system from various types. Some older models may use an embedded operating system, which may be stored on compact disk or data storage device.
The operating system offers a number of services for system programs, user interface, application programs and hardware. Applications access these services through system calls and device drivers from Hardware. Through the system call, the application can request service from the operating system, pass parameters, and receive the results of operations. Users can also interact with the operating system using some type of software or hardware that offers a user interface (UI), such as keyboards, typing commands to the command line interface (CLI) or using the keyboard and mouse with a graphical user interface (GUI, commonly pronounced " Gooey ").
Contemporary operating systems are widely used as Mac OS, Windows, Linux, BSD and Solaris. Although the servers are running Unix or its derivatives, embedded devices that separate the market between several operating systems.
