Operating systems (OS) can help computer users do many things, like managing and manipulating files and folders.. Operating systems also provide users the ability to control hardware components of a computer and its peripheral devices, like printers and scanners.. Chapter 3 Operating Systems Concepts 1 A Computer Model An operating system has to deal with the fact that a computer is made up of a CPU, random access memory (RAM), input/output (I/O) devices, and long-term storage.
