Digital technology treats all information as ________?

• A. Numbers
• B. Signals
• C. Voltages
• D. Codes

Answer: (A)

Digital information is treated as numbers because data is encoded into binary digits—0s and 1s. In digital systems, everything from text to images to sound is converted into sequences of these binary values. Those numbers are what the CPU manipulates with arithmetic and logic operations. The hardware then uses voltages or electrical signals to carry those bits, but the meaningful content is the numeric data encoded in binary. Codes and encoding schemes are just ways of representing real-world information as those numbers. So the central idea is that information is handled in digital form as numbers.
