What is the uses of OS?
An operating system (OS) is a set of programs that manages computer hardware resources, and provides common services for application software. The operating system is the most… important type of system software in a computer system. Without an operating system, a user cannot run an application program on their computer, unless the application program is self booting. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting for cost allocation of processor time, mass storage, printing, and other resources. 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 include Linux, Android, iOS, Mac OS X, and Microsoft Windows. (MORE)
