LRU Page Replacement Algorithm C Program

C Program For LRU Page Replacement Algorithm

Let us learn how to implement LRU Page Replacement Algorithm in C programming language. This code for Least Recently Used Page Replacement makes use of Arrays.

What is LRU Page Replacement Algorithm?

The page replacement algorithms help an operating system in deciding the memory pages that needs to be swapped out, written to the disk when a page of memory needs to be allocated in the system.


The LRU Page Replacement method is a marking algorithm. It keeps a track of the page usage in a given period of time. The LRU algorithm offers

The LRU algorithm offers optimum performance but is costly in its implementation. The LRU page replacement technique is modified for implementation, and its successors are

The LRU page replacement technique is modified for implementation, and its successors are LRU – K and ARC algorithms.

    A page fault normally is encountered when a referenced page in not found in the memory frames.

    The Least Recently Used Algorithm has a disadvantage that that its performance tends to degenerate under some of the most commonly used reference patterns.
