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

Operating systems use the Not Recently Used (NRU) page replacement algorithm as a fundamental page replacement tactic to control memory. Its major goal is to locate and remove pages from memory that haven't been accessed in a while. In this article, we will be discussing the NRU page replacement algorithm, the classes in it, the steps involved, the use cases, and also its benefits. The NRU algorithm Classes Based on their usage or reference bit, pages are divided into four classes by the NRU algorithm − Class 0 − Since they were loaded into memory, pages cannot be referenced (accessed) ...

Operating systems assign memory to processes using the memory management strategy known as non-contiguous allocation. This method divides memory into fixed-size blocks or partitions, and each partition can be assigned to a process according to its needs in terms of size. The non-contiguous allocation permits a process's memory to be dispersed among several regions in the main memory, in contrast to the contiguous allocation, where a process occupies a single block of memory. When working with processes of varying sizes, this strategy offers greater flexibility and effective memory utilization. In this article, we will be exploring what is Non-Contiguous Memory ...

Operating systems use the scheduling algorithm non-preemptive priority scheduling to choose the sequence in which processes are carried out. Each process is given a priority value based on specific criteria, and the procedure with the highest priority is carried out first. In this article, we will be discussing Non-Preemptive Priority, the much-needed Process of Prioritization with some examples, and some strategies to prevent starvation in terms of Non-Preemptive Priority. What is Non-Preemptive Priority? A process in non-preemptive priority scheduling keeps running until it is finished or voluntarily enters a waiting state. A higher-priority process is not halted by the scheduler ... Read More

Introduction A traditional approach to solving the critical section issue in programming simultaneously for both procedures is Peterson's algorithm. But since you said "N" processes, I presume you mean an altered Peterson's method that can manage over two procedures. Mutual exclusion is guaranteed by the initial Peterson's method for two distinct processes, yet it can't be immediately expanded to support N methods. Lamport's bakery algorithm, for example, is a deviation and an extra period of Peterson's algorithm which may be applied to N processes. The N process Peterson Algorithm Peterson's algorithm which can cope with N processes is called ... Read More

Introduction To avoid information loss and discrepancies, it is essential to make certain that discussed assets are obtained in an organized way when using concurrent programming methods, in which numerous threads or methods operate simultaneously. Mutual exclusion, which ensures that just a single string or procedure has access to a crucial area or resource that everyone shares at any point in time, is how this is accomplished. In this article, we will be talking about Mutual Exclusion in Synchronization, its various techniques, use cases, and example implementation through Python. What is Mutual Exclusion in Synchronization? A key component of synchronizing ... Read More

Mutual exclusion in a distributed system

Introduction A key principle of distributed systems is mutual exclusion, which prevents simultaneous operations or node locations from concurrently using common assets or crucial areas. When various procedures attempt to gain access to an identical asset at once, disputes, racial conditions, and discrepancies may result. Due to the absence of storage and the possibility of connection interruptions, errors, and node-to-node difficulties with communication and mutual exclusion turns more difficult in distributed systems. For achieving mutual exclusion in distributed systems, many techniques and procedures were established. In this article, we will be exploring the two main approaches, the various types, ...

Introduction In multitasking programming, mutex locks, also referred to as mutual exclusion locks, are synchronization basic functions used to prevent simultaneous possession of resources that are shared by numerous threads or procedures. The word "mutex" means "mutual exclusion." In this article, we will be exploring the components, types with examples, use cases, and implemented examples for Mutex Locks. What are Mutex Locks? A mutex lock makes it possible to implement mutual exclusion by limiting the number of threads or processes that can simultaneously acquire the lock. A single thread or procedure has to first try to obtain the mutex ... Read More
