Allows a single user to work on two or more programs that reside in memory at the same time?

This capability is known as multitasking, which enables a single user to run multiple programs concurrently. Multitasking is managed by the operating system, which allocates system resources such as CPU time and memory to each program, ensuring smooth operation and efficient use of the computer’s capabilities. This allows users to switch between applications seamlessly, enhancing productivity and user experience.
