I got hired at my current job as a software person, but I have a background in hardware so I try and make it into the NOC every excuse I get (promotability, don't you know). It always helps if sound like I have a vague idea what I'm talking about. :) I just made up my first ethernet cables the other day, and learned an interesting tidbit that I'm sure is beyond elementary to most of you, but may benefit someone else. What I was told is that the reason Cat 5 cable is so much more efficient is that each of the 4 pairs of wire is twisted at a different rate. This helps reduce the possibility of frequency synchronization for the EM fields the pairs create.
