1.1. What is an Operating system

1.1.1. n computing, an operating system (OS) is software (programs and data) that provides an interface between the hardware and other software. The OS is responsible for management and coordination of processes and allocation and sharing of hardware resources such as RAM and disk space, and acts as a host for computing applications running on the OS. An operating system may also provide orderly accesses to the hardware by competing software routines. This relieves the application programmers from having to manage these details.
