George Boole introduced a form of notation to describe binary statements in 1847
Digital devices of systems use only two values which can be expressed in several ways
high or low
true of false
on or off
Logic gates are usually integrated circuits which belong to semiconductor families such as or CMOS
An AND logic gate has to have at least two inputs so if the inputs are called A and B you would have to have both inputs on at the same time for the output to work.. So the sum is A*B = Y
An OR logic gate has to inputs if A and B are inputs. The output would be A+B. So the formula is A+B = Y
