Final answer:
Page tables are used to track the mapping between virtual and physical memory in computers, as part of an OS's virtual memory management system.
Step-by-step explanation:
Page tables are used to keep track of both main (real) and secondary (virtual) memory. They play a critical role in an operating system's memory management by maintaining a mapping between virtual addresses and physical addresses.
When a program accesses a memory address, the page table is referenced to find the actual location of the data in physical memory. If the data is not in the main memory, a page fault occurs, and the operating system must load the data from secondary memory into main memory.
This process is a part of the virtual memory management, allowing systems to run large applications even if not all of the data can be stored in main memory simultaneously.
Tables used to keep track of both main (real) and secondary (virtual) memory in a computer system are called Page Tables.
Page tables are a data structure used by the operating system to map virtual addresses to physical addresses. They are used to manage and organize memory efficiently and ensure that data can be accessed quickly.
