Let us learn how to implement FIFO Page Replacement Algorithm in C programming language. This code for First In First Out Page Replacement makes use of arrays.
What is FIFO Page Replacement Algorithm?
When a page fault occurs, the OS has to remove a page from the memory so that it can fit in another page in the memory.
These page replacement algorithms are used in operating systems that support virtual memory management.
FIFO Page Replacement technique is one of the simplest one to implement amongst other page replacement algorithms. It is a conservative algorithm.
It is a low-overhead algorithm that maintains a queue to keep a track of all the pages in a memory.
When a page needs to be replaced, the page at the FRONT of the Queue will be replaced. The FIFO page replacement technique is not implemented in operating systems nowadays.
