Q. 1 What is LINUX.Discuss the main features of LINUX.Explain the file system.
Ans. Linux is, in simplest terms, an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. The operating system (OS) relays instructions from an application to, for instance, the computer's processor. The processor performs the instructed task, then sends the results back to the application via the operating system. Following are some of the important features of Linux Operating System.
Portable - Portability means softwares can works on different types of hardwares in same way.Linux kernel and application programs supports their installation on any kind of hardware platform.
Open Source - Linux source code is freely available and it is community based development project. Multiple teams works in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
Multi-User - Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
Multiprogramming - Linux is a multiprogramming system means multiple applications can run at same time.
Hierarchical File System - Linux provides a standard file structure in which system files/ user files are arranged.
Shell - Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs etc.
Security - Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.
The tree of the file system starts at a forward slash (/). This directory, containing all underlying directories and files, is also called the root directory or the rootof the file system.
1. / root directory
Every directory under the root directory is
