Question

The table below shows a list of processes for a processor, the order in which they have arrived at the processor, and how many cycles of the processor each process will take to complete.

Task ID	Arrival order	Cycles to completion
Process A	1	12000
Process B	2	6000
Process C	3	2000

Using a first-come first-served scheduler, how many cycles will it take until Process B is completed?

Using a round-robin scheduler with each process getting 2000 cycles in turn, how many cycles will it take until Process B is completed?

Suggest a kind of scheduler to use when an operating system requires a lot of input/output from a user. Give a brief justification for your answer.
