Volatile memory preserves which types of data?

Volatile memory preserves which types of data?

• A. Email attachments
• B. Browser history
• C. Long-term user profiles
• D. Running processes and network connections

Answer: (D)

Volatile memory is temporary storage that keeps data only while power is on. It holds the system’s active state, including what programs are currently running and which network connections are open, because that information is needed for the computer to operate quickly. When power is removed, everything in this memory is lost, which is why volatile memory preserves running processes and network connections—the state of those tasks lives in RAM for immediate access. In contrast, email attachments, browser history, and long-term user profiles are stored on non-volatile storage like hard drives or SSDs, so they persist after power cycles and aren’t kept in volatile memory.
