Hello friends ,
Today I am starting a new category to let you know about "OPERATING SYSTEM PRINCIPLES" .........
What is an Operating System ?........
The basic definition of an Operating System is as follows :
" An operating system acts as an intermediary ( providing communication) between the user of a computer and computer hardware . "
The purpose of an operating system is to provide an environment in which a user can execute programs in a convenient and efficient manner.
An operating system is software that manages the computer hardware . The hardware must provide appropiate mechanisms to ensure the correct operation of the computer system and to prevent user programs from interfering with the proper operation of the system .
Internally , operating system vary greatly in their makeup , since they are organized along many different lines . The design of a new operating system is a major task. It is important that the goals of the system be well defined before design begins . These goals forms the basis for choices among various algorithms and strategies .
Because an operating system is large and complex , it must be created piece by piece. Each of these pieces should be a well delineated portion of the system , with carefully defined inputs , outputs and functions .
