Which term refers to the characteristic of data that outlives the process that created it?

• A. Data availability
• B. Data persistence
• C. Data confidentiality
• D. Data integrity

Answer: (B)

Data persistence is the property that lets data survive beyond the life of the program that created it. When data is persisted, it’s written to non-volatile storage—like a disk or database—so it remains available after the process ends or the system reboots. This is why saved files, database records, and logs endure after you close an application. This concept differs from data availability (being accessible when needed), data confidentiality (protection from unauthorized access), and data integrity (keeping data accurate and unaltered).
