Swapping items between memory and storage is called _____.

• A. Caching
• B. Loading
• C. Uploading
• D. Paging

Answer: (D)

The concept being tested is how an operating system manages memory beyond what's physically installed. Paging is the mechanism that moves fixed-size blocks called pages between RAM and disk to free up memory and provide the illusion of a larger address space. When RAM fills up, the OS writes some pages to a special area on disk (swap space) and later loads them back as needed. This is different from caching, which simply keeps copies of frequently accessed data in faster storage to speed up access; paging actually swaps whole pages between memory and storage to manage what’s currently in use. Loading would just bring data into memory without the systematic swapping in and out that paging performs. Uploading isn’t related to memory management.
