Which memory type is used to temporarily store open apps and document data while the device is on?

• A. Non-Volatile Memory
• B. Open Source Software
• C. Internet
• D. RAM (Random Access Memory)

Answer: (D)

RAM is the temporary workspace the processor uses to keep the data and instructions for apps and documents you’re actively using. It’s fast and volatile, meaning everything stored in it is kept only while the device has power; when you turn off or restart, that information is cleared. This is why you can have many apps open and switch between them quickly—the system loads the necessary data into RAM for quick access.

Non-volatile memory, by contrast, preserves data even when power is off, which is important for saving files long-term, but it isn’t the fast, temporary store used for active work. Open source software isn’t a type of memory, and the Internet is a network resource, not a memory type, so they don’t fit the role of temporarily holding open apps and documents.
