Scheduling is a form of decision-making that plays an important role in many disciplines It is concernedwith the allocation of scarce resources to activities with the objective of optimizing one or more performancemeasures Depending on the situation resources and activities can take on many different forms

What is CPU scheduling in operating system?
CPU SCHEDULINGThe Scheduler Selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state 2.
What is round-robin (RR) scheduling?
To solve this problem, we will introduce a new scheduling algorithm, classically referred to asRound-Robin (RR)scheduling [K64]. The basic idea is simple: instead of running jobs to completion, RR runs a job for a time slice(sometimes called ascheduling quantum) and then switches to the next job in the run queue.
What is the history of scheduling?
We will now do just that, presenting a series ofscheduling policies(sometimes calleddisciplines) that various smart and hard-working people have de- veloped over the years. The origins of scheduling, in fact, predate computer systems; early approaches were taken from the ?eld of operations management and ap- plied to computers.
