smp = symmetrical multi-processors - i.e. dual CPU machines.

smp version supplies support for multiple processors.

How many CPUs in that box? (smp is for multiprocessors)

I found the "LNAG - How do I install a program I downloaded from the Internet?" link to be very useful in teaching me how to instal different packagase..thank you..but what command do I type to extract a file that has .tar.bz2 at the end?

I usually use these flags:

tar -xvjpf *.tar.bz2

For their meanings and actions see:
man tar
info tar

I don't think you need the "p"...actually just -xjf do the work...

Unless you don't need the permissions of the tarball preserved.
