Logic Gates and Propagation Delay

logic gates are subject to what's called propagation delay. This means that it takes some finite period of time for electrical signals to pass through the wires and transistors. Propagation delay places a limit on how fast you can run computers, because the faster you try and run them, the more you push up against ation delay. That's why there's been a race to try and make transistors as small as possible in order to fit more of them on a circuit. But i'm now going to mostly stop talking about transistors and focus on the logic gates which perform more useful functions than just bolian operations. Get to what that means in a little bit.
