Detailed explanation-1: -With a single-input gate such as the inverter or buffer, there can only be two possible input states: either the input is “high” (1) or it is “low” (0).
Detailed explanation-2: -Most logic gates have two inputs and one output. Logic gates are based on Boolean algebra. At any given moment, every terminal is in one of the two binary conditions, false or true. False represents 0, and true represents 1.
Detailed explanation-3: -"Logic 0” and “logic 1” represent binary digits (0 and 1) or Boolean logic conditions (true and false). Thinking in terms of logic 0 and logic 1 allow engineers to design circuits and logic gates at a high level of abstraction that is removed from implementation considerations.
Detailed explanation-4: -Digital devices operate on binary values so there are only two allowable digital states. Each of these states is called a Logic State. A variety of names is used to label these two states.
Detailed explanation-5: -AND is a Boolean operation, an operation that takes values that are either “true” or “false", and then outputs “true” or “false” based on a logical manipulation of those inputs. In logic gates, we consider 1 to be true and 0 to be false.
