A NOR gate is another fundamental logic gate used in digital electronics. It stands for “Not OR,” and it produces a high output only when both of its inputs are low; otherwise, it produces a low output.

The truth table for a NOR gate is as follows:

The symbol for the NAND Gate:

In other words, if any input to the NOR gate is low, the output will be high. It is the opposite behavior of the OR gate.

NOR gates are used in digital circuits for various purposes, such as implementing logical functions, constructing more complex logic gates, and inverting signals. They are widely used in digital design, computer architecture, and other electronic systems.
