appreciate the responses guys thanks,
as I was saying "I know nothing."
and have another dumb question: is it possible to plug in a seperate PC into a laptop and then use the laptop's monitor for that 2nd PC ?
(I have an old tower at a friend's house I want to load some music/transfer some files etc. onto a hard drive, but have no monitor besides a laptop at that location) was hoping just to bring PC cable not an extra monitor
