The operating system maintains a table that tracks allocated frames, total…

Concept: In a paged memory-management scheme, the operating system keeps two distinct bookkeeping structures: a page table (one per process) that maps that process's logical pages to physical frames, and a frame table (one for the whole system) with one entry per physical frame, recording whether the frame is free or allocated — which lets the OS report the total, allocated, and available frame counts.

Application: The stem's description — a single table tracking allocated frames, total frames, and available frames in physical memory — is exactly the frame table's job, so the word that correctly completes “______ table” is Frame.

• A page table maps one process's logical pages to physical frames; it is a per-process structure and does not by itself report system-wide allocated, total, and available frame counts.

• Mapping names the logical-to-physical address-translation relationship, not a named tracking table.

• Since exactly one of the listed words fits, treating “more than one” as correct, or assuming “none” of them fit, are both incorrect.

So the correctly completed name is the Frame table.
