What type of gate does this input-output table correspond to?

input: output:
a b ?
0 1 1
0 0 0
1 0 1
1 1 1

A logic gate is the fundamental building block of a digital circuit. The type of gate that these input-output tables correspond to is 2 inputs OR Gate. The output Q is true if EITHER input A “OR” input B is true, giving the Boolean Expression of: ( Q = A or B ).
