A NAND gate is a fundamental building block in digital electronics. It stands for “Not AND,” and it produces an output that is the inverse of the AND operation. In other words, it produces a low output only when both of its inputs are high; otherwise, it produces a high output.

The truth table for a NAND gate is as follows:

The symbol for the NAND Gate:

NAND gates are commonly used in digital circuits for various purposes, such as inverting signals, implementing logical functions, and constructing more complex logic gates like NOR, XOR, and others. They are widely used in both digital design and computer architecture.
