Description: Preemptive multitasking is a task management method that allows the operating system to interrupt a running task to give way to another. This approach is fundamental to ensuring that multiple processes can run efficiently and fairly in a multitasking environment. In this model, the operating system has full control over the CPU time allocated to each task, allowing it to interrupt a task at any moment, even if it has not completed its execution. This is achieved through the use of timers and interrupt signals, which enable the operating system to decide when it is appropriate to switch contexts between tasks. Preemptive multitasking is especially relevant in various computing environments, including embedded systems and mobile devices, where efficiency and quick response are crucial. Additionally, this method helps prevent a task from monopolizing the processor, which could lead to poor system performance. In summary, preemptive multitasking is an essential component that allows the simultaneous execution of multiple processes, optimizing resource use and enhancing user experience.
