Heres a diagram I whipped up in paint. Upwind is only call that if you dont land, like if you mess up and have to go around, or enter the traffic pattern from that side. I just realized that this illustrates a right hand patter. It should be noted that most of the time the traffic pattern goes to the left. The legs of the pattern have the same names either way. Hope it helps!

As Tacit mentioned, patterns normally go to the left.  Therefore, they're often referred to as "standard" and "non-standard", the former being a left pattern and the latter being a right-hand one.
