Which data type is described as discrete ON/OFF electrical signals?

• A. Analog data
• B. Digital data
• C. Pulse data
• D. Binary data

Answer: (B)

Discrete ON/OFF signals are described as digital data because digital data uses fixed, separate levels to represent information, usually two states such as on and off. This makes the signal binary in nature, with clear transitions between defined logic levels, unlike analog data which can vary continuously. While pulse data concerns encoding information with timing or width of pulses, it does not by itself define the continuous ON/OFF nature of the signal. Binary data is basically the two-state concept, but the standard term for two-state signaling in most instrumentation and control contexts is digital data. So, digital data best captures the idea of discrete ON/OFF signaling.
