Basic Computer Operations
Session 1
As we all know that computer is a very useful machine. It is very important to properly start the computer and after finishing the work, it needs to be properly shut down. If the power of the computer is switched off, and the files you were working on were not closed, the files and the operating system may get corrupted.
Operating System
An operating system is the basic software that controls the computer. It serves as an interface between the user and the computer.
Some of the functions of Operating system are:
It manages all the devices of a computer and keeps track of the status of the device, whether it is busy or not.
It also checks whether the device is functioning properly or not. It also controls software resources of the computer.
t manages the computer memory and keeps track of which memory space is in use by which program and which space is free.
It manages the structure of the files and directories on a computer system. It keeps track of the amount of disk space used by a specific file.
It allows you to create, copy, move and delete files.
Types of Operating Systems
We have already discussed about some commonly used operating systems in class IX. These are:
DOS DOS (Disk Operating System)
Windows It is an operating system developed by Microsoft.
Linux It is an operating system designed for personal computers. It is a free and open-source software
Mobile operating Systems
Android STUDY MATERIAL
Symbian
Windows Phone
iOS
Types of Operating Systems
The different types of operating systems are as follows:
Interactive (GUI-based) A graphical user interface is a user-friendly operating system in which commands can be entered by clicking/double-clicking/right clicking a mouse. Windows operating system is an example of an interactive operating system.
Single-user , single-task operating system This type of operating system allows only one user to do a task on the computer and one thing at a time.
Single-user, multi-task operating system This type of operating system is used on Desktop computers, laptops, where a single user can operate on several programs at the same time. For example, Windows, Apple MacOS are examples of single-user multi task operating system.
Multi-user A multi-user operating system enables multiple users to work on the same computer at different times or simultaneously.
Real Time A real time operating system is used to control machinery, scientific instruments, like robots, in complex animations and computer controlled automated machines. A real-time operating system is a computing environment that reacts to input within a specific period of time. It manages the resources of the computer so that any particular operation is executed in the same amount of time every time it is executed. Windows CE and Lynx OS are examples of real-time operating systems.
Distributed A distributed operating system runs on a set of computers that are interconnected by a network. It combines the different computers in the network into a single integrated computer and storage location. Windows, UNIX, and LINUX are examples of distributed operating systems.
