Computer software Operating System

A computer system has many resources (hardware and software), which may be require to complete a task. The commonly required resources are input/output devices, memory, file storage space, CPU etc. The operating system acts as a manager of the above resources and allocates them to specific programs and users, whenever necessary to perform a particular task. Therefore operating system is the resource manager i.e. it can manage the resource of a computer system internally. The resources are processor, memory, files, and I/O devices. In simple terms, an operating system is the interface between the user and the machine.
Introduction to Operating Systems

The notion of software
The program - is a specific set of ordered operations for a computer to perform. The collection of all programs designed to run on a computer, called the software computer.
A computer is considered as a system consisting of interrelated parts: hardware (technical devices) and software.

Operating system (OS)

Conclusion
It has proved itself as a valuable alternative to various important application including office applications and operating systems. Various state governments and public sector institutions have chosen it as a possible alternative to closed source software due to different and varying reasons including low cost, being reliable and fiexible, with innovative trends and freedom from manufacrurers.
