What is a characteristic of an OR gate?

An OR gate outputs a logic high when any input is high. If any input is 1, the output becomes 1; the gate only outputs 0 when all inputs are 0. This is true for two inputs as well as for multiple inputs. For example, with inputs 0 and 1, the output is 1; with inputs 1 and 1, the output is 1; with inputs 0 and 0, the output is 0. The other statements would imply the gate behaves like something else (for instance, producing 0 when any input is 1, or producing 1 when all inputs are 0), which isn’t how an OR gate operates.
