What are page replacement algorithms?
Page replacement algorithms are strategies used in operating systems to manage memory. They decide which memory pages to swap out when new pages need to be loaded.
Can you explain some common page replacement algorithms?
Sure! Some common algorithms include Least Recently Used (LRU), First-In-First-Out (FIFO), and Optimal Page Replacement.
How does the LRU algorithm work?
The LRU algorithm keeps track of page usage over time and replaces the least recently used page when a new page is needed.
What are the advantages and disadvantages of these algorithms?
LRU is efficient but can be complex to implement. FIFO is simpler but may not always be optimal. Each has its trade-offs.
