What are logic gates? Give the logic symbol of NOT and AND gates.

An OR gate is operated by using positve logic. What role will the OR gate play if we use negative logic? Or, Show that, the truth table of an OR gate in negative logic is similar to that of an AND gate in positive logic.

What is logic gate? Distinguish between AND and OR gates.

The NOR gate is logically equivalent to an OR gate followed by :-
