Use of yum command

We can install any apllication/package online in linux using yum command

yum stands for Yellow dog Updater, Modified (YUM).
It is a free software/open source command line package management utility for RPM-compatible Linux operating systems. It was developed by Seth Vidal and a group of volunteer programmers

Procedure to install a package/application

a) Internet should be connected
b) Go to terminal
c) Login as root
d) Just use yum command as 'yum install <package/application>'
e.g: to install lynx
>yum install lynx

This will download and install lynx. As for as I know I have used it in redhat, ubuntu and fedora and it worked to perfection.
