What’s Actually In The Page Table?
Explore how page tables map virtual memory addresses to physical frames using data structures like linear page tables. Understand key components such as valid bits, protection bits, and other flags that control memory access and management. This lesson helps you grasp the fundamental role of page tables in efficient memory virtualization and address translation.

Linear page table
Let’s talk a little about page table organization. The page table is just a data structure that is used to map virtual addresses (or really, virtual page numbers) to physical addresses (physical frame numbers). Thus, any data structure could work. The simplest form is called a linear page table, which is just an array. The OS indexes the array by ...
