A Multitasking Operating System allows a computer to run multiple tasks or processes simultaneously. This means that users can switch between different applications, such as a web browser and a word processor, without closing any of them. The operating system manages the allocation of resources, ensuring that each task has the necessary CPU time and memory. There are two main types of multitasking: preemptive and cooperative. In preemptive multitasking, the operating system controls the distribution of CPU time, while in cooperative multitasking, applications voluntarily yield control. Popular examples of multitasking operating systems include Windows, macOS, and Linux.
