[ILUG] Network cable questions

[Kathryn Cassidy (User Account)]

Hello,

Some time ago there was a discussion about home 
networking where someone said they thought you could 
only attach two computers directly with cat 5 cable 
(ie. without a hub) if it was some "special cross-over 
cable" and not just normal twisted pair.

Can anyone confirm this?  Also, is there a name for 
this type of cable, or if I go to peats/maplin asking 
for cross-over cat 5 cable will they know what I'm 
talking about.

Thanks,
Kathryn.
