Which term describes data or signals represented by a finite number of values?

• A. Digital
• B. Analog
• C. Bit
• D. Array

Answer: (A)

Data or signals that use a finite number of values are discrete. Digital describes this approach because digital data is encoded as a limited set of distinct values (like 0 and 1) and processed in binary form. This discreteness is what makes digital representations different from analog, which varies continuously and can take infinitely many values. A bit is the smallest unit of digital information, while an array is just a collection of items and doesn’t define how values are represented. So the term for data or signals with a finite number of values is digital.
