Topic: Memory Virtualization

This week in the course, we continued to delve further into memory virtualization and how we manage memory. In the lab, we worked with the FIFO (First-In-First-Out) page replacement strategy, a method used to manage page entries in memory. Paging is a memory management technique that divides both logical memory (virtual memory) and physical memory into fixed-size blocks called pages and frames. The logical addresses are divided into pages, which are then mapped to available frames in physical memory using a page table.

The FIFO strategy does not account for whether a page has been accessed recently or frequently. Instead, it strictly evicts the page that has been in memory the longest. On the other hand, the LRU (Least-Recently-Used) approach takes into consideration the recency of use, replacing the page that has not been accessed for the longest time.
