Topic: Explain Different Components of Operating System

Q. What is an Operating System? Explain Components of an Operating system.

Operating System

An operating system is a set of programs that manages all computer components and operations. An operating system works as an interface between the user and the computer hardware.

Examples of Operating Systems

Some popular operating systems are DOS, windows, Unix, Linux, and OS/2.
Without Operating System, a computer cannot do anything. Users interact with the computer through operating system. Operating system acts as an interface between a user and computer hardware.

Explain Different components of operating system


Components of an Operating system

An Operating system has many components to manage all resources of a computer system as following:

1.    Process Management

CPU can perform one task at one time. If there are many tasks, operating system decides which task should get the CPU first.

2.     Main Memory Management

Operating system manages memory (RAM)for many running programs. It allocates memory area to different programs. It deallocates the memory area when a program is terminated.

3.    Secondary Storage Management

Operating system manages secondary storage. It manages the stored files and folders on disk in a proper way so that minimum space is consumed and faster access of files when required.

4.    I/O System management

It manages Input/output operations. It controls Input/Output devices like mouse, keyboard, monitor and printer etc.

5.     File Management

    File management component performs all activities related to files. It manages files for example creation of file or deletion of files.

6.         Protection System

          There are many processes of different users in memory at a time. So operating system provides protection component so that no process can interfere with another process's activity.   

7.     Networking

Modern Operating system provides networking services. Operating system provides access to shared resources by networking system.

8.     Command Interpreter system

Operating system provides command interpreter component. Command line interpreter is used for reading and executing user commands. The user will type commands on command line interface which will be executed.

There are some other uses of Head section too, like linking external style sheets and Java script code, etc. Head section starts with the <HEAD> tag and ends with the </HEAD> tag. <TITLE> tag is used to display a title of...

Types Of Network Topology

Today, we will types of network topology . What is a Network Topology? Definition of Network topology is the shape of the network . It is the physical layout of connected devices in a network. It tells us how a network will look like. Network Topology ( Definition 2) : The way in which the connections are made among all the network entities is called the topology of the network. Network Topology ( Definition 3) :Network topology specifically refers to the physical layout of the network, e.g., the location of the computers and how the cable is run between them. Network Topology ( Definition 4) :The physical topology of a network refers to the configuration of cables, computers, and other peripherals. The characteristics of a network depend upon the network topology selected. types of network topology Explain different types of network Topology Different network topologies are as follows: 1. Bus Topology 2. Ring Topology 3. Star Topology 4. Tree Topolo...
