In this article, we will explore LRU(Least Recently Used Algorithm) and FIFO(First In First Out) numerical, their flowcharts and their use cases as well. Least Recently Used Algorithm Popular page replacement algorithms used in operating systems and cache management systems include the LRU (Least Recently Used) technique. By replacing the least recently used page in a cache when a new page needs to be loaded, it seeks to reduce the amount of page faults. Example − Let's assume we have a cache with a capacity of 3 pages and a sequence of page requests: 2, 3, 1, 4, 2, 1, 5, ... Read More

Numerics are essential for understanding the complex facets of disc storage since they offer a hands-on, practical method to grasp fundamental ideas. We may investigate how disc capacity, performance, and utilization are estimated by delving into numerical examples, helping us to understand the fundamentals of efficient storage management. Example − Think of a cloud service provider, for instance, that provides its customers with access to file storage. The service provider stores customer files, including documents, photos, and multimedia content, on disc storage. The disc storage system is built to support high data throughput and offers reliable file access. In this article, ... Read More

The NTFS file system used by Windows operating systems includes NTFS (New Technology File System) junction points. In essence, junction points are a kind of symbolic link that lets you join one directory to another inside the same file system. In this article, we will explore NTFS Junction Points, it’s architecture diagram, their use cases, example code in C#, and their benefits as well. NTFS Junction Points The main purpose of junction points is to build directory-level links, which let you change the path's destination to another location on the same volume. This can be helpful in a variety ... Read More

Concurrent programming employs the notion of lock variable synchronization to make sure that several threads or processes can safely access shared resources without coming into race situations or inconsistent data. It offers a mechanism to manage the order in which threads or processes are executed, enabling them to have exclusive access to shared resources when required. In this article, we will explore the mechanism of lock variable synchronization, use cases, and an example code snippet in C as well. Lock Variable Synchronization Utilizing a shared variable, often known as a lock or mutex (short for mutual exclusion), to ... Read More

An operating system (OS) is a piece of software that controls and manages the hardware and software resources of a computer while also giving users a simple way to interact with the system. By serving as a conduit between the user and the computer hardware, it makes it easier for different system parts to coordinate and communicate with one another. In this article, we will explore different operating systems along with their latest versions and features as well. Top Operating Systems Today's systems use a variety of operating systems. Here are a few of them − macOS Microsoft Windows ... Read More

Introduction The disc scheduling method N-Step-SCAN (also called N-Step-LOOK) determines the sequence whereby disc requests for input/output are handled. It is a development for the SCAN (Elevator) method, which functions by moving the disc arm in a particular direction and responding to demands there as long as it receives no more inquiries or requests from that guidance, at which point it switches directions. The N-Step-SCAN algorithm adds an option, N, that specifies how many requests must be handled in a particular direction beforehand transforming. N-Step-SCAN support N demands in a particular direction, irrespective of whether or not there are still ... Read More
