Introduction In the realm of operating systems (OS), process scheduling plays a crucial role in ensuring efficient CPU utilization and smooth multitasking. The scheduler is responsible for deciding which process gets to execute at any given time, ensuring that system …
Process Schedulers in Operating Systems Understand the key concepts of process schedulers, their types, and roles in operating systems, with real-life examples from Windows, UNIX/Linux, and macOS. Essential knowledge for GATE and UGC NET preparation. Introduction Process scheduling is one …
Discover the fundamentals of CPU scheduling in operating systems. This guide covers key terminologies, different scheduling algorithms, and their impact on system performance, complete with numerical examples. Introduction CPU scheduling is a fundamental concept in operating systems that ensures efficient …
Introduction to Process Control Block (PCB) 1. Introduction to Process Management: Definition: Process management is a core function of the Operating System (OS) responsible for managing processes, from creation to termination. Example: Compiling and running a C/C++ program demonstrates how …
Introduction to Process Structure in Memory When a program runs on a computer, it is loaded into the system’s memory, transforming it from a passive entity (a program) into an active one (a process). The memory structure of a process …
Context Switch: What It Is: Context switch happens when the CPU shifts from executing one process to another. This involves saving the current process’s state (like its position in the task, data in registers, etc.) and loading the state of …
Imagine you’re working on your computer, and you have several tasks open—maybe a web browser, a music player, and a word document. But, you can only focus on one thing at a time. Your brain quickly switches between these tasks, …
Introduction In the realm of modern operating systems, efficient process management is crucial for multitasking and maintaining system stability. The Process Control Block (PCB) is a fundamental data structure that plays a central role in process management, providing the operating …
Introduction Process management is a core function of any operating system (OS), crucial for the smooth execution of multiple programs on a computer. It involves overseeing processes—programs in execution—by allocating resources, scheduling tasks, and ensuring that all operations run efficiently. …
Introduction Sequence points in C are critical for writing reliable and predictable code. They define specific points during program execution where all side effects of previous operations are guaranteed to be complete, and no side effects from subsequent operations have …
Introduction to Distributed Operating Systems A Distributed Operating System (DOS) is an advanced operating system that manages a group of independent computers and makes them appear to be a single computer. These interconnected computers communicate through a shared network, allowing …
Introduction to Time-Sharing Operating Systems A Time-Sharing Operating System allows multiple users to access and use a computer system simultaneously by allocating a fixed time slice or quantum to each task. This system ensures that all tasks receive CPU time, …
