OR

This outputs high when any of the inputs are high.

XOR

This outputs high only if ALL of the inputs are different (for binary applications, only 2-inputs are possible).

NOT

This inverts the input. If input is high, output is low, and vice-versa.

By applying this logic to the previous gates, we can come up with a few more:

NAND

This outputs the opposite of an AND gate, which means that the output is high if the inputs are anything but all on.

NOR

This is the opposite the OR gate, which means the output is high only if all inputs are low.

XNOR

This is the opposite of the XOR gate, which means the output is high only if all inputs are the same.
