Final answer:
The third component of Linux's three-level page table structure is the page table entries (PTEs). This paging mechanism helps translate virtual memory addresses to physical memory addresses and consists of page directories, page tables, and PTEs.
Step-by-step explanation:
Linux makes use of a three-level page table structure consisting of the following types of tables: page directory, page table, and page table entries (PTEs).
In the context of the Linux operating system's memory management, when a process is running, the Linux kernel uses a three-level paging mechanism for translating virtual memory addresses to physical memory addresses. This mechanism involves the following:
A page directory, which contains entries pointing to page tables.
Page tables, which have entries that point to the final level in this structure.
The final level consists of the actual page table entries or PTEs, that store the mapping to physical memory addresses.
Each level of the table allows the operating system to efficiently manage and access memory, granting flexibility in how memory is allocated, accessed, and managed across various processes.
