Determining the time quantum for a job is a critical task.
Given the assumptions that the average switching time between processes is s, and the average amount of time an I/O bound process uses before generating an I/O request is t (t >> s). Discuss the effect of each of the following quantum settings denoted by q.
a) q = infinity b) q is slightly greater than zero c) q = s d) s < q < t e) q = t f) q > t
