What is an Operating System?
An Operating System (OS) is a software that acts as an interface between computer hardware components and the user. Every computer system must have at least one operating system to run other programs. Applications like Browsers, MS Office, Notepad Games, etc., need some environment to run and perform its tasks
Functions of Operating system
In an operating system software performs each of the function:
1. Process management:- Process management helps OS to create and delete processes. It also
provides mechanisms for synchronization and communication among processes.
2. Memory management:- Memory management module performs the task of allocation and
de-allocation of memory space to programs in need of this resources.
3. File management:- It manages all the file-related activities such as organization storage,
retrieval, naming, sharing, and protection of files.
4. Device Management: Device management keeps tracks of all devices. This module also
responsible for this task is known as the I/O controller. It also performs the task of allocation and de-allocation of the devices.
5. I/O System Management: One of the main objects of any OS is to hide the peculiarities of
that hardware devices from the user.
6. Secondary-Storage Management: Systems have several levels of storage which includes primary storage, secondary storage, and cache storage. Instructions and data must be stored in primary storage or cache so that a running program can reference it.
7. Security:- Security module protects the data and information of a computer system against malware threat and authorized access.
8. Command interpretation: This module is interpreting commands given by the and acting system resources to process that commands.
Conclusion:-
• Without operating system the computer cannot run the application and we cannot do
He
work in the computer, therefore operating system is very important in computer.
• As operating system controls and coordinates the use of the hardware among the
re
various uses, we can say that it plays a very important role in the computer system.
• An operating system is needed in order to use various application on your computer
and wireless device
