An operating system is a program which manages all the computer hardware.
It provides the base for application program and acts as an intermediary between a user and the computer hardware.
The operating system has two objectives such as:
Firstly, an operating system controls the computer’s hardware. The second objective is to provide an interactive interface to the user and interpret commands so that it can communicate with the hardware.
The operating system is very important part of almost every computer system.
Managing Hardware
The prime objective of operating system is to manage & control the various hardware resources of a computer system.
These hardware resources include processer, memory, and disk space and so on.
The output result was display in monitor. In addition to communicating with the hardware theoperating system provides on error handling procedure and display an error notification.
If a device not functioning properly, the operating system cannot be communicate with the device. Providing an Interface
The operating system organizes application so that users can easily access, use and store them.
Providing an Interface
The operating system organizes application so that users can easily access, use and store them.
It provides a stable and consistent way for applications to deal with the hardware without the user having known details of the hardware.
If the program is not functioning properly, application and displays the appropriate error message
Computer system components are divided into 5 parts
Computer hardware
Operating system
Utilities
Application programs
End user
It is a program that directly interacts with Hardware
The operating system is the first encoded with the Computer and it remains on the memory all time thereafter.
System goals
The purpose of an Operating system is to be provided by an enviroments in which user can excute an program.
Its Primary goal are to make the computer system convenience for the user.
Its secondary goal are use to computer in efficent manner.
