among Linux distributions and enable

software applications to run on any

compliant Linux system.

Uptime is valued as a matter of pride

(remember, Linux and other UNIX systems are

most often used as servers, which are

expected to, and do, stayup 24/7/365).

After the original installation, you can install

or remove most software without having to

reboot your computer for almost any softwarebesides the kernel itself.

User can usually change to another Linux, UNIX, or BSDsystem and still use the exact same software!

Most open source software projects were created

to run on any UNIX-like system and many also run onWindows systems, if you need

them to.

If it wont run where you want it to, chances are that

you, or someone you hire, can port it to the computeryou want. (Porting refers to modifying an applicationordriver so it works in a different computerarchitecture or operating system.)

yum.

After you learn your way around Linux youll

find that (given the right permissions on your

computer) most configuration is done in plain

text files that are easy to find and change. In

recent years, simplified graphical interfaces

have been added to make working with

configuration files even

The X Window System (providing the framework foryour Linux desktop) has been around longer thanMicrosoft Windows.

The KDE and GNOME desktop environments providegraphical interfaces (windows, menus, icons, and soonward) that competitor those on Microsoft systems.

User have the freedom to choose lightweight

window managers instead as well.

Ease-of-use problems with Linux systems are rapidly

evaporating.

Linux, in its most basic form, has no corporate agenda or bottomline to meet.

You are free to choose the Linux distribution that suits you, look atthe code that runs the system, add and remove any software youlike, and make your computer do what you want it to do.

Linux runs on everything from supercomputers, to cell phones,and everything in between.

Many countries are rediscovering their freedom of choice

and making the switch at government and educational levels.

France, Germany, Korea, and India are just a few that have taken

notice of Linux. The list continues to grow
