Which term describes storing or transmitting information by discrete impulses?

• A. Analog
• B. Digital
• C. Continuous
• D. Binary

Answer: (B)

The main idea is how information is carried using separate, distinct signals rather than a smooth, continuous variation. Digital describes storing or transmitting information with discrete impulses, encoding data in on/off pulses that create distinct values. This stands in contrast to analog, where signals vary continuously in amplitude or other properties rather than in steps. While binary is a common way to implement digital data using two states, the overall term for this approach is digital.
