Discrete data.

Discrete data.

• A. graphics tablet
• B. digital data
• C. disk cache
• D. encryption

Answer: (B)

Discrete data means values that are distinct and separate, typically things you can count or categorize rather than measure on a smooth curve. Digital data embodies that idea because it’s made up of discrete units—bits that are either 0 or 1—organized into symbols and files. This stepwise, countable nature is what makes data digital and different from a continuous form. A graphics tablet is just a device for capturing input, not a description of data type. A disk cache is a memory area used to speed up data access, not about whether data is discrete or continuous. Encryption is a process that transforms data to protect it, not about the inherent granularity of the data.
