What is the role of page replacement algorithms in memory management, and give examples of such algorithms.

  • Control the allocation of pages to processes
  • Determine which pages to replace when memory is full
  • Manage swapping of pages between main memory and secondary storage
  • Optimize the layout of pages in memory
Page replacement algorithms play a crucial role in memory management by deciding which pages should be swapped out of main memory when the memory is full and a new page needs to be brought in. Examples of page replacement algorithms include FIFO (First-In-First-Out), LRU (Least Recently Used), and Optimal algorithms. FIFO replaces the oldest page, LRU replaces the least recently used page, and Optimal replaces the page that will not be used for the longest time in the future. These algorithms aim to minimize page faults and improve overall system performance.
