I have no idea what I'm doing so please be gentle. I am a long time PC user and today I got my first mac. It is old...really old. A centris 650 that I got for free from work. I was pretty surprised at how fast it is. Anyway. What I would like to know or at least pointed in the right directing is... Can the mac and pc be on the same network? If so what do I need to do to get it running? Any help would be greatly appreciated.
