Final answer:
CPU scheduling is foundational to multiprogramming operating systems, which allows multiple programs to run simultaneously by allocating CPU time effectively.
Step-by-step explanation:
CPU scheduling is the basis of multiprogramming operating systems.
CPU scheduling is a process that allows the CPU to allocate its time among various tasks or processes to maximize efficiency and utilization, resulting in multiple programs being able to run simultaneously.
Hence it is fundamental to the concept of multiprogramming, where the operating system enables several jobs to be in memory at the same time.
