Demand Paging is a memory management technique where pages of a process are loaded into physical memory only when they are needed, rather than loading the entire process at once. Implementation Steps: Maintain Page Table: Keep a page table that tracks which pages are in physical memory and their locations. Handle Page Faults: Implement a mechanism to detect page faults and fetch pages from disk when needed. Use Page Replacement Algorithms: Apply algorithms (like FIFO or LRU) to manage memory when replacing pages. Update and Access: Ensure that once a page is loaded, the process can access it using updated page table entries.
