A multitasking operating system allows a computer to run multiple tasks or processes simultaneously. This capability enables users to switch between applications, such as browsing the internet while listening to music, without noticeable delays. The operating system manages the allocation of resources, ensuring that each task receives the necessary CPU time and memory. These systems use techniques like time-sharing and process scheduling to efficiently handle multiple tasks. In time-sharing, the CPU rapidly switches between tasks, giving the illusion that they are running at the same time. This enhances user experience and productivity by allowing seamless interaction with various applications.
