Final answer:
The page table contains the base addresses of each page in the physical memory, used by the operating system for memory management.
Step-by-step explanation:
The page table contains the base address of each page in physical memory. This table is used by the computer's operating system to manage memory efficiently. When a program needs to access data that is not currently in the main memory, the operating system looks up the page table to find out where the data is stored on the disk. Once located, the necessary data is transferred to the main memory, and the process is updated to reflect this change in the page table.
