Introduction Disk scheduling algorithms are critical in computer operating systems for managing and optimizing the use of a computer's hard drive. Disk access time can significantly impact the performance of the entire system, and a poorly implemented disk scheduling algorithm can result in long wait times and reduced overall efficiency. First-Come-First-Serve (FCFS) and Shortest Seek Time First (SSTF) are two common disk scheduling algorithms used in modern operating systems. FCFS processes requests in the order they are received, while SSTF prioritizes processing requests with the shortest seek time. Understanding the differences, advantages, and disadvantages of these algorithms can help system ... Read More

In case of multiprogramming, CPU needs to be scheduled, so that multiple works can be performed simultaneously in less time or at a same time. By CPU scheduling it is decided which of the processes in the ready queue is to be allocated in the CPU. Thus, there are so many CPU-scheduling algorithms in order to schedule CPU. FCFS scheduling is one of the CPU-scheduling algorithms. FCFS (FIRST-COME, FIRST-SERVED) Scheduling FCFS is considered as simplest CPU-scheduling algorithm. In FCFS algorithm, the process that requests the CPU first is allocated in the CPU first. The implementation of FCFS algorithm is managed ... Read More

Introduction In computer operating systems, disk scheduling algorithms are used to manage the order in which input/output (I/O) requests are processed by the disk controller. One such algorithm is FCFS (First-Come, First-Served), which is a simple and straightforward scheduling algorithm that processes I/O requests in the order in which they arrive in the queue. In FCFS, when a process generates an I/O request, it is added to the end of the queue of pending requests. The disk controller then services the requests in the order they were added to the queue, with the oldest request being processed first. Once ... Read More

Introduction Fair-share CPU scheduling is a scheduling algorithm used in operating systems that aims to allocate CPU resources fairly among different user or process groups. The fair-share scheduler assigns a weight to each process or group based on its historical usage and allocates CPU resources based on these weights, ensuring that no group is starved of resources for an extended period of time. This allows for better resource utilization and provides equal opportunities for all groups to access the CPU. Fair-share scheduling is commonly used in multi-user systems and virtualized environments where multiple users or virtual machines share a single ... Read More

In operating systems, a bad block is a sector on a dick drive or a flash of the computer system which is not usable due to a permanent damage to the disk like physical damage of the disk surface or failed transistors of flash memory. In this article, we will discuss the bad block in detail along with their different types, causes, replacement, etc. So let’s get started with the basic definition of bad block in operating system. What is a Bad Block in Operating System? The storage area of a memory device such as disk drive or flash drive ... Read More

Introduction Expansion buses in PCs are interfaces that allow peripheral devices to connect to the motherboard and communicate with the CPU and other components of the system. Expansion buses typically consist of one or more expansion slots, and different types offer varying data transfer rates and maximum bandwidth. By providing a pathway for data transfer between peripheral devices and the CPU, expansion buses enable users to increase the functionality and performance of their computer systems. The ability to add new hardware components or upgrade existing ones through expansion buses has helped to extend the lifespan of PCs and has made ... Read More

Embedded operating systems and desktop operating systems are two distinct categories of software systems that serve different purposes. Embedded operating systems are designed to run on specialized devices, such as medical devices, automotive systems, or industrial equipment, which perform specific functions. Desktop operating systems, on the other hand, are designed to run on personal computers or laptops and support a wide range of applications. Understanding the differences between embedded and desktop operating systems is important for developers, engineers, and anyone working with software systems. Key Areas Covered What is an Operating System? What is Embedded OS? Advantages and Disadvantages ... Read More

Introduction Edge chasing is a technique used in operating systems and computer hardware to handle events or signals that occur asynchronously with the processor's clock cycle. This technique involves detecting and responding to events or signals as they occur, or as close to their occurrence as possible, to minimize the delay between the event and the system's response. Edge chasing algorithms are used to implement this technique and are an essential component of interrupt handling, input/output operations, and other time-sensitive tasks in modern computer systems. Basic Edge Chasing Algorithms The two basic edge chasing algorithms are polling and interrupts. Polling ... Read More

Dynamic Partitioning is a memory management technique used in computing systems to allocate and deallocate memory resources as needed. Unlike static partitioning, dynamic partitioning allows for the creation of new memory partitions or the resizing of existing ones at runtime. Dynamic Partitioning plays a crucial role in modern computing systems, where efficient memory utilization is essential for optimal system performance. This article will provide an overview of dynamic partitioning, including how it works, its types, advantages and disadvantages, real-world applications, challenges, and future prospects. Definition of Dynamic Partitioning Dynamic partitioning is a computer memory management technique that allows the system ... Read More
