If 1 is inputted into a NOT gate, what will the output be?	0
If 1 is inputted into an AND gate, will the output be 0? Yes or no?	No
If both 1 and 0 are inputted into an OR gate, what will the output be?	1
What is a NOT gate?	a NOT gate is a gate that outputs something opposite to what was put in
What is the definition of an AND gate?	AND gates take two bits as inputs. If both inputs are 1 then the output is 1. Otherwise the output is 0.
What is an OR gate?	OR gates take two bits as inputs. If both inputs are 0 then the output is 0. Otherwise the output is 1
