Operating Systems - Virtual Memory
This document summarizes a lecture on virtual memory. It discusses how virtual memory uses page tables to map virtual addresses to physical addresses, allowing processes to access more memory than is physically available. It describes demand paging, where pages are loaded on demand from disk, and the translation lookaside buffer (TLB) that caches translations to improve performance. Common page replacement algorithms like least recently used (LRU) and first-in first-out (FIFO) are also summarized.
