I have installed Ubuntu and I have several questions.

I have an old Sony Vaio Desktop from 2001.

The computer has 124 megs of memory and has one hard drive of about 100 gigs. Is Ubuntu the best choice for a Linux distribution? It seems to run a little slowly.

How do I set up internet connection? I launched FireFox and I tried a few web sites. I have not tested the new connection to my router. I would like to try to see if the software is set up before I test my cable connection on my other computer. How do I do this?

I have an old Lexmark all-in-one printer that had worked with the old Windows XP OS. How do I get a printer driver for Ubuntu?
