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 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

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

Introduction Disk scheduling and management are essential components of a computer's operating system that handle the organization and access of data on a disk. Disk scheduling algorithms determine the order in which the read/write head of the disk moves to access data, which impacts the efficiency and speed of accessing data. Some commonly used disk scheduling algorithms include First-Come-First-Serve, Shortest Seek Time First, and SCAN. Disk management, on the other hand, involves tasks such as disk partitioning, formatting, and file system creation. It ensures that the disk is properly utilized, optimized for performance, and maintained to prevent data loss or ... Read More

A disk operating system (DOS) is a type of operating system that manages data on a disk storage device. It was widely used in the 1980s and 1990s, particularly on IBM-compatible personal computers. Understanding DOS commands is essential for users who still rely on DOS for certain tasks or for those who want to learn about the history of computing. DOS commands are also useful for troubleshooting and fixing problems on older systems. The purpose of this article is to provide an overview of basic and advanced DOS commands, as well as tips for using them effectively. Definition of Disk ... Read More

Introduction Concurrency in operating systems refers to the ability of an operating system to handle multiple tasks or processes at the same time. With the increasing demand for high performance computing, concurrency has become a critical aspect of modern computing systems. Operating systems that support concurrency can execute multiple tasks simultaneously, leading to better resource utilization, improved responsiveness, and enhanced user experience. Concurrency is essential in modern operating systems due to the increasing demand for multitasking, real-time processing, and parallel computing. It is used in a wide range of applications, including web servers, databases, scientific simulations, and multimedia processing. However, ... Read More
