I make no statement here as what I say is the definitive way of doing things. if you have a better way to do something please feel free to add to this discussion.**

Welcome back & to more about Linux.

governments making the switch to Linux?
Try making that search in Google, you will find that there are several governments that are making that switch? Why is that you might be asking and mostly it's due to the restrictive nature of Microsoft's Licensing or their (E.U.L.A. : End User License Agreement ) If you really want to scare your self, try actually reading M$'s E.U.L.A. this is a document that basically absolves Microsoft from all damage to you / your company / your computer / your relationship / if your dog pukes on the carpet after you install / or WWIII ensues after your completion of it's install :)


Most companies will phase out the older distributions of Linux and switch to the newer ones this for them will not create much of a problem as they have IT departments that are responsible for ensuring that any change over will go as smooth as possible, but for the average user we have to ensure that by switching especially with older hardware that we are not bogging down the system to the point of un-useability, It then falls on us to do a little research and reading to find out what will work and what wouldn't be a good choice. ( Ever notice how Windows does this too.. Each successive version of windows has made greater and greater requirements on your computer and it's hardware? )
some sites www.linuxiso.org, www.linuxquestions.org, www.distrowatch.com. Or visit any of the various Linux discussion forums and someone there might even be able to point you in the right direction or even point you to a different operating system (OS) For your needs.

On to Partitions... We all have partitions weather you realize it or not, think of a partition as taking a pie and cutting it into slices. Each peace becomes independent of the whole. and therefore has it's own properties and abilities. ( You probably never thought about pie having abilities. but HEY it's the best I could do at the moment :) hahaha ) at any rate each of these pieces can be formatted to hold and use different Operating systems ( OS's ) each different OS requires a different type of file system Eg; FAT 16, FAT 32, NTFS or any of the various Linux file systems. I am not going to expound on the various file systems I only mention them here so that ppl have a basic understanding of what is meant by File System.

On To User Accounts:

We all may or may not have heard of the term ?User Account? in windows there's 2 accounts that are made when we are done installing the system the ?Guest account? and an ?Administrator Account? there is other accounts in Windows but most ppl only have these two.. It is beyond the scope of this to explain the different abilities of each account I only intend to help ppl to make the connection between Windows way of doing things and the Linux way of doing things.

In the Windows World ( WW ) we have as previously mentioned two accounts ?guest? and ?Administrator? in the Linux world ( LW ) we also have 2 accounts.. or as many as is needed but again beyond the scope of what I am trying to accomplish here :)

In WW the Administrator account is pretty self explanatory administrator's are able to make changes to the system install / software, remove software. all without prompting the person behind the keyboard for a password because they are logged in as Administrator... In the LW the ( ROOT user or SU ) *super user * are able to do these same things... The fundamental difference between the WW way of doing things and the LW way of doing things is that in Windows you are almost always logged in as administrator there for installing software is for you an easy and painless way of doing things this however comes with a ?HEFTY PRICE? and that PRICE is SECURITY. This is how Spy ware, Viruses and Trojan horses can make their way on to the system as windows in administrator mode will not make any concerns as to weather or not the user actually wants this software on the system or not. But in the LW Linux Kinda forces you to make a normal user account this account can use the system and most of the hardware and most of the software installed on the system these abilities can be more liberal or strict depending on the rules and guidelines setup by the Administrator of that computer. * Note this is also possible in the WW it's just not as widely used.* In the LW a normal user doesn't have the ability to install ?SYSTEM WIDE? software as this requires the approval of the administrator. You will also need the root password to install & make this program run. Thus you have security, and only you can say when this program is able to be installed because you have the password to the system.

A good idea is to establish a user account for yourself as well even though you may be the root to your system. Say you wanted to install a game?. you would need the root password to let it install on your system. Most program just need it during the install process, but some require the root pass every time but that is rare with some distributions or versions of Linux.

Well I hope this sheds more light on Linux for you. We welcome all ideas and information to this subject. So don?t hesitate to reply. And also if you have other ideas to what you would like to see here, please share or ask. We are here to help in your research and any ideas you would like to see.
