I am trying to solve a question about scheduling using Round Robin. I was able to answer most of the parts but I am badly stuck on two parts:
Code:
 Quantum = 3 time units
Process arrival time = 0

CPU burst - 4 time units
I/O burst  - 5 time units
CPU burst - 8 time units
I/O burst  - 6 time units
CPU burst - 10 time units
I have to state the transitions it will go through and indicate if it is voluntary or not.

AND

If the process attempts a division by zero in the third time unit of the second CPU burst what change will it have on the lifetime of the process.

Please help me..
Thanx
Jules
