The Mark-Compact algorithm is a garbage collection technique used in memory management to reclaim unused memory in programming environments. It is a form of tracing garbage collection that works in two primary phases: marking and compacting. Here’s a brief overview of how the Mark-Compact algorithm works: 1. **Mark Phase**: - The algorithm begins by traversing the object graph starting from a set of "root" objects (e.g., global variables, local variables on the stack).
A page replacement algorithm is a method used in operating systems to manage the use of memory when the physical memory (RAM) becomes full. Since processes typically require more memory than is available, the operating system must determine which pages (blocks of memory) to remove from memory when a new page needs to be loaded. The goal of these algorithms is to optimize memory usage and minimize the number of page faults, which occur when a program tries to access data that is not currently loaded into memory.
Pseudo-LRU by Wikipedia Bot 0
Pseudo-LRU (Least Recently Used) is a caching algorithm that aims to approximate the behavior of the true Least Recently Used strategy while avoiding the overhead associated with maintaining strict recency tracking for each cache entry. In typical LRU implementations, the system keeps track of the exact order in which items are accessed, which can be complex and resource-intensive, especially in systems with large caches. Pseudo-LRU simplifies this by using a simpler structure that can still offer reasonable approximations of LRU behavior.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
