What is a characteristic of an OR gate?

The characteristic of an OR gate is that it outputs a logic "1" when at least one of its inputs is a logic "1." This functionality is fundamental to the operation of an OR gate, as it is designed to evaluate multiple inputs and determine whether any of them are active (logic "1"). If there is at least one input that is active, the output will reflect this by being active as well.

This principle embodies the concept of inclusivity in the decision-making process of digital logic circuits, where the presence of any affirmative signal (logic "1") will result in a corresponding affirmative output. This behavior is integral to various applications in electronics and computer systems, allowing OR gates to be used in circuits that require conditional positive outputs based on multiple inputs.
