Memory management:- Memory management module performs the task of allocation and de-allocation of memory space to programs in need of this resources.

It also provides mechanisms for synchronization and communication among processes.

Process management:- Process management helps OS to create and delete processes.

In an operating system software performs each of the function: Some typical operating system functions may include managing memory, files, processes, I/O system & devices, security, etc.īelow are the main functions of Operating System: Functions of Operating System

Some most famous mobile operating systems are Android and iOS, but others include BlackBerry, Web, and watchOS. Mobile operating systems are those OS which is especially that are designed to power smartphones, tablets, and wearables devices. It provides the capability to serve to manage data, user, groups, security, application, and other networking functions. Network Operating System runs on a server. Distributed Operating Systemĭistributed systems use many processors located in different machines to provide very fast computation to its users. Examples: Military Software Systems, Space Software Systems are the Real time OS example. Real time OSĪ real time operating system time interval to process and respond to inputs is very small. The processor time (CPU) which is shared among multiple users is termed as time sharing. Time-sharing operating system enables people located at a different terminal(shell) to use a single computer system at the same time. Multi-Tasking/Time-sharing Operating systems In this type of OS, every user prepares his or her job on an offline device like a punch card and submit it to the computer operator. The user of a batch operating system never directly interacts with the computer. To speed the same process, a job with a similar type of needs are batched together and run as a group. Some computer processes are very lengthy and time-consuming. 64 Bit Operating Systemįollowing are the popular types of OS (Operating System):

Difference between Firmware and Operating System.

Disadvantages of using Operating System.

Examples of Operating System with Market Share.

It is not possible for the user to use any computer or mobile device without having an operating system. The OS helps you to communicate with the computer without knowing how to speak the computer’s language. Applications like Browsers, MS Office, Notepad Games, etc., need some environment to run and perform its tasks. Every computer system must have at least one operating system to run other programs. An Operating System (OS) is a software that acts as an interface between computer hardware components and the user.
