NRI Financial Technologies Associate Software Engineer Interview Questions and Answers

NAND, NOT, and AND are logical operators used in digital electronics.

• NAND is a combination of NOT and AND operators.

• NAND returns true only when both inputs are false.

• NOT operator negates the input value.

• AND operator returns true only when both inputs are true.

Constructing a NOT gate using only NAND gates, demonstrating the universality of NAND logic.

• A NAND gate outputs false only when all its inputs are true.

• To create a NOT gate, connect both inputs of a NAND gate to the same signal.

• If the input is 0, the output will be 1; if the input is 1, the output will be 0.

• Example: For input A, connect A to both inputs of the NAND gate: NOT A = NAND(A, A).
