When you use a computer or smartphone, it feels like everything is happening at the same time. You can listen to music, browse the web, download files, and receive notifications — all without thinking about how the system manages it. Behind this smooth experience is an important operating system responsibility known as task scheduling . Task scheduling determines which process gets to use the CPU, when, and for how long . Without it, modern multitasking would not be possible. Why Task Scheduling Is Necessary The CPU is one of the most valuable resources in a computer system. At any moment, many processes want to use it, but only one process can execute on a single CPU core at a time. Task scheduling exists because: Multiple processes compete for CPU time Some tasks are more urgent than others Fairness is required, so no task is ignored System responsiveness must be maintained The operating system acts as a traffic controller, deciding how CPU time is shared among ru...

  Modern computers feel effortless to use. We open a browser while music plays in the background, notifications appear, files download, and documents are edited—all at the same time. This smooth experience often feels natural, but behind the scenes, a complex system is carefully managing every action. That system is the operating system. Task management is one of the most important responsibilities of an operating system. Without it, computers would struggle to perform even simple operations efficiently. What Is a “Task” in a Computer System? In computing, a task refers to any program or process that requires the computer’s attention. Opening an application, typing a document, streaming a video, or checking for updates—each of these is treated as a task. The operating system does not view these tasks emotionally or intelligently. Instead, it sees them as processes that need processor time, memory, and system resources. Its job is to manage these demands in a fair and efficient...

  Introduction When we switch on a computer or unlock a smartphone, we immediately interact with apps, files, and screens. Rarely do we think about what makes all these actions possible. Behind every click, swipe, and command lies a powerful system working quietly in the background—the Operating System . An operating system, often called an OS, is the foundation that allows users and hardware to work together smoothly. Without it, a computer would be nothing more than a collection of electronic components with no coordination or purpose. Understanding the role of an operating system is essential for anyone who wants to truly understand how computers function. What Is an Operating System? At its simplest level, an operating system is a special type of software that manages the entire computer. It controls how hardware resources are used and provides a friendly environment for users and applications. Rather than interacting directly with hardware—which would be complex and impr...
