Question
The algorithm which replaces the block which has not been referenced for awhile is called ………
ans.
- LRU
- Random Replacement
- FIFO
- Optimal Page Replacement
Solution
The algorithm which replaces the block that has not been referenced for a while is called Least Recently Used (LRU).
LRU keeps track of page usage over time, replacing the least recently accessed page when a new page needs to be loaded into memory. It is effective in approximating the optimal page replacement but uses historical reference information rather than future references. Other options like Random Replacement, FIFO (First In First Out), and Optimal Page Replacement serve different purposes but do not target pages that have not been referenced for a duration.
In summary, the correct answer to your question is: LRU (Least Recently Used).
