Q. Or is it the same thing? I don't really know anything about Linux and Ubuntu so I just wanted to find out some of this stuff before I get the OS on my computer.
A. Linux is the Kernel. All Linux Distros. (Distributions) including Ubuntu are built upon the Linux Kernel
http://en.wikipedia.org/wiki/Linux_kernel
I thoroughly recommend Linux Mint 9 Main Edition which is built upon Ubuntu 10.04 Its easy to install and easy to use plus it comes with much of the software you are likely to need preinstalled
Linux Mint 9 Download

The Perfect Desktop - Linux Mint 9 (Isadora)
http://www.howtoforge.com/the-perfect-desktop-linux-mint-9-isadora
Linux Mint 9 User Guide Download pdf.
http://www.linuxmint.com/rel_isadora.php
You download the ISO. image of Linux Mint 9 then you need to create a Bootable LiveCD for installation
Linux Mint 9 can also be run direct from the LiveCD from Booting up without touching your Hard Drive
Also worth considering :
Fedora Remix (Fedora with elements of Linux Mint)
http://fcoremix.wordpress.com/2010/05/25/lucky-13/
http://iso.linux.hr/community-fedora-remix/
http://docs.fedoraproject.org/en-US/Fedora/13/html/User_Guide/
Again Fedora Remix can be run direct from the LiveDVD without touching your Hard Drive
Also you can try out as many different Linux distros. as you like on LiveCD until you find the one thats right for you DISTROWATCH.COM gives full listings (second lists the major distributions)

What is a Linux shell script used to verify/track user activity on a network?
Q. I would like to use a script that will verify that no users are logging in or log in after hours. It will keep track of all user activity and/or report any unauthorized users from gaining access to the network.
A. It's not particularly elegant, but you can create an /etc/nologin file (including a denial message in it if desired) and then set up a cron job to move or rename it to allow/disallow access at certain times.
If the file exists, it does not allow remote connections (any, including root, as far as I'm aware, so take care ). To prevent complete remote lockout, the file is deleted by the system upon startup if it exists.
If you need actual access control lists, this is not the method for you. If you have a couple users, you can create dual /etc/passwd files and change the un-authorized user login shells to /sbin/nologin (Fedora/RH/CentOS) or /bin/false (Debian/Ubuntu). Maintaining that for more than a couple becomes a chore though, and if you need to do this on a larger or long-term basis, there are better, non-script solutions.

How do I change the root password in Linux?
Q. I have an old Linux PC but I forgot the root password.
How do I reset the password?
I tried to go to the root directory. However, when I typed "su", it prompted me for the root password. Since I have forgotten it, I cannot type it in and I, therefore, cannot go to the root directory to change the password.

A. Boot into the system at the physical console. Go into single user mode (check the documentation for your distro).
Make your way to the command prompt. Again consult the specifics for your distro.
Once there you should be able to run "passwd root" or similar to reset the password.
The physical console it ultimate power.
NOTE:
Some distros do not have a root account per se (Ubuntu comes to mind). Regular accounts are put in a super user list that are allowed to "su" or "sudo". In this case the password in question is the password of the account you are already logged in to. If you are allowed to "go super" you will temporarily assume "root" powers.
