Page replacement algorithms

Page replacement algorithms are methods used by computer systems to decide which memory pages to remove when new data needs to be loaded into limited RAM. Since RAM can't hold everything at once, these algorithms determine the optimal page to swap out, minimizing delays or errors. Different strategies, like removing the least recently used page or the one not needed for the longest time, help ensure the system runs smoothly and efficiently. They are essential for managing memory effectively in multitasking environments.
