How operating system coordinate a task?

Operating systems coordinate tasks through a process known as multitasking, where they manage the execution of multiple processes concurrently. They use a scheduler to allocate CPU time to each task, ensuring that all processes receive fair access to resources. Additionally, the operating system employs mechanisms such as interrupts and context switching to handle task priorities and manage system resources efficiently, allowing for smooth execution and responsiveness. Overall, these functions ensure that tasks run effectively without interfering with one another.
