round robbin

Question

Consider a CPU which needs to run a round robbin scheduing algo . Size of program is 200kb . It has been stated that hard disk has transfer rate of 2Mbps . Assume that there are  no head seeks and average latency is 10msec.  The acceptable time quantum for effective CPU utilisation is  _____________ msec

Comments

@A_I_$_h Can you tell what is "effective CPU utilisation"? Is it in percentage or something else?

Time taken to load a program from hard disk to main memory is 112.4 Mili seconds so when it comes to the main memory it is directly given to the CPU and executed .But the time Quantum depends on burst time of process so for best CPU utilisation if there is only one process the time Quantum should be equal to the burst time of the process.
