J-K flip flops

variable

I'm trying to understand how the J-K flip flop works and how to draw the timing diagrams. I was reading about it on wikipedia and was wondering if someone could explain this to me: "Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop." What do they mean by set and reset? Does set mean the balue of Q goes to 1 and reset means Q goes to 0 or something and how does the clock affect it? I did look at the timing diagram provided and it was confusing. I understood the toggling part and table but not anything else. Thank you.
