Question

Consider that we have a multi-programmed computer in which each job has identical characteristics i.E. In one computation period t for a job, half the time is spent in i/o and the other half in cpu activity. Each job runs for a total of n periods. If four simultaneous jobs, assuming that the period t is distributed as i/o first half, processor second half, with round robin scheduling is used and i/o operations can overlap with processor operation, then what is the average turn around time?

Answer 1

turn around time = waiting time + burst time
