The term "NOR" refers to a logical operation used in digital electronics and computer science. It is a combination of the NOT and OR operations, producing a true output only when all inputs are false. In other words, if any input is true, the output will be false. This makes NOR a fundamental building block in creating complex logical circuits. In Boolean algebra, the NOR operation is represented by the symbol "↓" or sometimes as "¬(A ∨ B)", where A and B are the inputs. The NOR gate is widely used in integrated circuits and computer architecture due to its ability to create any other logical function, making it a versatile tool in digital design.
