RedHat Linux 5. Bash Shell for regular user vs root...what does it mean? what are the differences?

I don't understand the concept of PATH or what it does for you.  Can anyone explain?   Is it linking me to other directories so that I can use the tools within those directories without having to cd to that directory itself?  Does it give me permissions to perform tasks?  I dont get it.  Thanks.

its referring to an environment variable.  The 'path' environment var is a list of directories that will be checked for programs when an exact location is not already known.  For example, you run a command in the terminal, it searches the locations in the path var to find an instance of the program for the command you ran, and executes it from there.
