These are the commands you will need when you want a specific command to execute, only when certain conditions are met. In case you don't understand the table, here is a simplified version.
AND
OR
XOR
NOT
NAND
NOR
XNOR Both have to be true
At least one has to be true
Only one must be true (Exclusive OR)
Makes a true a false and vise versa
At least one has to be false (NOT AND)
Both have to be false (NOT OR)
Both have to be false or true (NOT EXCLUSIVE OR)
