Introduction to Operating SystemsA 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.
4. The notion of software
The program - is a specific set of orderedoperations 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.

Systems of programmingSystem software includes the operating system
and service programs.
Operating System - a set of programs that provide
operation of all computer devices and gives the user
access to computer resources.
The most common operating system for personal
computers:
Windows
Apple

ConclusionIt 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.
