Yeah, but it helps to understand the theory before throwing all the 
obfuscating real-world complexities into the mix.

OK, I'll take a look.

Or, to put it more correctly, an arrangement of transistors is an 
imperfect implementation of how a logic gate is supposed to behave.

Presumably if you were to build a gate out of water valves or lego 
bricks, it would have a different set of imperfections.
