LINUXOPERATING SYSTEMKiran,MCA, KCL-IMT, Jalandhar [email protected] Abstract: Linux Operatingsystem is used in everywhere like in cars , smart phones , home appliance etc.1Before the platform to run desktops, server across the globe , it was themost secure , reliable , easy to use operating system. It is the most popularversion of UNIX Operating System.
Linux is open source OS ,its code is freeand it means that anyone can used it ormodify the OS according to his / her requirements. Objective : The goal of our study is to gain anunderstanding of the main challenges any person face in practice when they workwith Linux Operating System and they feel that it is the though or complexOperating System to use. Method : I can understand the topic of Linux OS fromdifferent – different books or from internet then I can write the informationabout Linux OS which is helpful to many people to understand the Linux OS andits features also. Results : This article is very helpful to those peoples whohas interested to know about the Linux OS.
Introduction: LINUX isan operating system like window XP ,window 7 , window 8 , and MAC Operating System X. Linux OS is a computeroperating System and also known as GNU /LINUX. The Operating System and the software used in it are developed bythe volunteers, employees work in companies or in organisations.This Operating System is free to use for everyoneand everyone has a freedom to used it. It could run on any computer and needed only small pieces of codecalled kernel2.Linux is used for a large network system and it isbased upon UNIX system. It is the most interesting Operating System in now adays.
An operating systemis software that manages all of the hardware resources associated with yourdesktop or laptop. Who develop the LINUX ????? LINUX isan operating system or a kernel which is generated as an idea in the mind of bright and young student of computer science Linus Torvalds3 in 1991. He work on UNIX OS and he wanted to improved it further. LinusTorvaldsBut unfortunately ,the designers of UNIX OS , canrejected his suggestions. Then he thought that launching that type of operatingsystem which will easily modify , receptive to changes according to thesuggestions of the users. The OS is consist of following : The kernel: This is actually called “Linux”.
The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the “lowest” level of the OS4. The Bootloader: The Bootloader is a software that can manages the boot process of our computer system. The boot processing is known as Bootstrapping , which means that starting up of a computer system. During the process of bootstrapping (starting up of a computer) , the kernel is loaded into the memory of the computer system. Daemons: These are background services like printing , sound , scheduling , etc that are start up / or runs during the process of booting , or after you log into your desktop. The Shell: Shell is the that type of interface where the user can works through typing the commands in text interface.
This is also called Command line interface. The shell can allow the user to control his / her computer via just typing the commands into a text interface. Desktop Environment: The user can interact with the Desktop Environment. There are many kinds of desktop environments are like GNOME , KDE , XFCE etc. Each desktop environment consists of many built-in applications such as file managers , configuration tools , web browsers , games etc.
Applications: Like Ubuntu Linux has the Ubuntu Software Center which allows you to quickly search among the thousands of apps and install them from one centralized location5. ADVANTAGESOF LINUX OS :Well supportedMore SecureVirus freeCompatible with others OSMore powerful OSRun on any kind of hardware Whywe used LINUX ????? / Features of Linux OS :Linux is used for the following reasons or features:Secure:It is more secure as compare to the other operating system. It is free fromvirus attacks. If you installed Linux , you need not to install anti – viruswhen you can use the Linux OS. Free Operating system : It is free ofcost as compare to the other operating system like windows , we can pay for purchasing it.For getting the licence of window , we can also pay for it. Notneed of rebooting : If you installed many software in linuxoperating system , you need not reboot your system again and again. OpenSource : Linux is open source operating system which meansthat any user can get the source code of the software and then modified itaccording to his / her requirements.
Portable: Portablemeans that the software can works on the differents kinds of hardware. The Linux kernel and theapplication programs can supports their installation on any kind of hardwareplatform. Reliabilty:Linux is reliable OS because of betterBackground Processes. when a background process is enabled or start or run in the Linux OS , the OS will only use it for as longas it needs to and then disable or stopped it until needed again6.
Fig: Reliability of Linux OS Multiuser: Multiusersmeans that more than two users can works Linus OS on the same time. Themultiple users can also access the resources of computers , RAM , memory etc. Multiprogramming: Multiprogrammingmeans that in Linux OS , multiple programs can run at same time on one system.
