What are the states of a digital I/O signal?

Explanation:
Digital I/O signals carry two distinct states that represent binary information. In practical systems, those states are wired as a high or a low level, but for programming and data processing they’re given precise numeric meanings. Assigning ON to 1 and OFF to 0 provides a universal, machine-readable encoding that supports arithmetic, logic operations, and communication between components. While High/Low or On/Off describe the sensing or qualitative feeling of the state, only the ON=1 / OFF=0 convention provides a fixed numeric mapping needed for consistent control logic and data handling.
