[Snort-users] Tap and Hub

Typically speaking, vendors referring to hubs these days are referring to switches.  Just to double check and make sure I hadn't missed the last few years, I asked one of our CCNPs and he gave me a funny look when I asked him about gigabit hubs... so yeah, hubs only do 10 mb half-duplex.  Actually, here I started to brainstorm what a gigabit hub's traffic would look like and, wow, talk about collision city...

Anyways, yeah, go look at gigabit taps.  A tap is going to copy at line-speed, any traffic going through it to the tapped ports and you won't have to worry about numerous issues such as collisions and exceeding the bandwidth of the device.

What is the difference between a network hub and a network tap?
Maybe a stupid question, but is there a "gigabit hub" on the market or for
gigabit should I look for a tap?
(span port is not possible in my case...)
Thanks for the info.
