Input Output In Linux Operating System

The operating system (English, keyboard-based system, or OS) is a program that manages computer hardware and software resources and is also the kernel and cornerstone of a computer system.     Operating systems have such basic services as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating networks, and managing file systems. Operating system is the management of the computer system of all the hardware resources, including software resources and data resources, control program operation, improve Man-machine interface, provide support for other application software ...
