C are run concurrently on a computer system.
Three tasks, A, B, and C are run concurrently on a computer system.
Task A arrives first at time 0, and uses the CPU for 100 ms before finishing.
Task B arrives shortly after A, still at time 0. Task B loops ten times; for each iteration of the loop, B uses the CPU for 2 ms and then it does I/O for 8 ms.
Task C is identical to B, but arrives shortly after B, still at time 0.
Assuming there is no overhead to doing a context switch, identify when A, B and C will finish for each of the following CPU scheduling disciplines:
a. FIFO
b. Round robin with a 1 ms time slice
c. Round robin with a 100 ms time slice

d. Shortest job first
