In digital information, what two states are used to represent data?

• A. High and Low
• B. On and Off
• C. Positive and Negative
• D. Yes and No

Answer: (B)

Digital data is stored and processed using two distinct states, which makes information binary and easy for machines to read. In digital circuits, these two states are represented by something being on or off. When a voltage is high enough, the signal is considered on; when it’s near zero, it’s off. This clear on/off distinction is what lets computers encode binary digits, 1s and 0s, reliably and consistently.

That’s why “on and off” is the best description for how data is represented in digital information. High and low describe voltage levels in a physical sense, but the essential idea for data representation is the existence of two discrete states, on and off. Positive and negative and yes and no convey meaning or polarity rather than the hardware-level binary states used to store information.
