Ok I am a relative beginner to poker, especially poker forums like this one was just wondering about a few terms...

What's a set? I'm guessing four-of-a-kind...

100/BB, how do you work this out and what does it tell you? I've just seen it mentioned a few times across this forum

What's a Poker Tracke?

If anyone has time to explain these bits and bobs it'd be much appreciated,
