What two signals represent the states in a binary system?

In a binary system, which is foundational to digital electronics and computing, the two states are commonly represented by the concepts of "On" and "Off." This is because binary systems utilize two distinct states to perform calculations and represent data. When a signal is in the 'On' state, it indicates a high value or presence of a signal, often corresponding to '1'. Conversely, the 'Off' state indicates a low value or absence of a signal, commonly corresponding to '0'.

While options like "Zero and One" also accurately describe binary values numerically, the terms "On" and "Off" are more representative of the functional states in many practical applications, such as electrical circuits and logic gates, where these terms provide a clearer understanding of the system's operation.

The other choices touch on states that can represent binary in different contexts, but "On" and "Off" are the most universally accepted in the realm of digital logic and signal representation.
