Gigabit cross-over cable
Posted by BPuhl on July 27, 2008
Was talking with Dean this evening, and we wanted to swap a bunch of files around. “Bunch” being multiple GB. Started off all well and good over the wireless network, but we were still lacking something…ahh..that’s what it was: “Throughput”
Since both his laptop and mine have gigabit ports, we decided to cable them together to get a little more “transfer” into the “file transfer” process.
Fortunately I decided to think out loud when I said, “Sure, I think I have a cross-over cable”…because that gave him the opportunity to say, “Gigabit is smarter than that, you don’t need a cross-over cable anymore, it will automagically figure it out” – to which I appropriately responded: “Huh? What?”
So yeah – turns out that you don’t need cross-over cables anymore, gigabit network ports will automagically figure it out, and (according to Dean) they will even figure it out when you have gigabit on one side and 10/100 on the other side. This obviously explains the long line of cross-over cables outside the unemployment office.
(for all of you who are thinking to yourselves, “yeah, duh! You mean you didn’t know that already?” – No, I didn’t)
