In digital logic, what operation does an OR gate perform?

Explanation:
An OR gate performs disjunction. Its output goes high (1) if any input is high, and stays low (0) only when all inputs are low. This means signals can be combined so that at least one active input turns the output on. It’s different from an AND gate, which needs all inputs active to produce a high output, and from a NOT gate, which simply inverts a single input. For example, if one input is 1 and the others are 0, the output is 1. If both inputs are 0, the output is 0. This behavior embodies the OR operation in digital logic.
