Boolean Algebra and Logic Simplification - Technical MCQs

Q1:

The NAND or NOR gates are referred to as "universal" gates because either:

A can be found in almost all digital circuits

B can be used to build all the other types of gates

C are used in all countries of the world

D were the first gates to be integrated

ANS:B - can be used to build all the other types of gates

NAND and NOR gates can be used in place of all basic gates that AND ,OR and NOT.
They can be used to implement any circuitory.
We can use only one type of universal gate to implement any circuit.
