What is flip flop?
A flip flop is a circuit which is capable of remembering the value which is given as input. It can be used as a basic memory element in a memory device. These circuits are capable of storing one bit of information.
Question: 10
What are the different types of logic gates?
There are three fundamental logic gates namely, AND, OR and not.
Also we have other logic gates like NAND, nor, XOR and XNOR. Out of these NAND and NOR gates are called the universal gates.
