The property of a system software that enables it to execute more than one program at a time is referred to as "multitasking". Multitasking is a feature of the operating system that allows multiple programs to run simultaneously on a computer system, sharing the resources of the system such as CPU time, memory, and input/output devices. This enables users to perform multiple tasks at the same time without the need to wait for one task to finish before starting another. In multitasking, the operating system schedules the execution of the programs in such a way that each program gets a fair share of the resources and the overall performance of the system is optimized.
