Concept: Paged memory management uses two different kinds of bookkeeping. A page table belongs to a process and translates that process’s virtual pages, whereas a system-wide frame table has one entry for each physical frame and records its allocation state and ownership.

Application: The stem asks for the structure that tracks allocated, available, and total physical frames across memory. That description corresponds to the system-wide frame table, so the blank is completed by Frame.

• “Mapping” names the logical-to-physical translation relationship rather than the physical-frame inventory.

• “Page” identifies a virtual-memory unit; a process’s page table maps those pages to frames.

• “More than one of the listed options” and “None of the listed options” are meta-choices, but the standard terminology identifies one offered word.

Cross-check: The distinction can be tested by changing processes: each process receives its own page table, while the operating system still needs one global view of which physical frames are free or allocated. That global view is the frame table.

Result: The completed name is Frame table.
