• There are 10 different processes running on a workstation. Idle processes are waiting for an input event in the input queue. Busy processes are scheduled with the Round- Robin time sharing method. Which out of the following quantum times is the best value for small response times, if the processes have a short runtime, e.g. less than 10ms?
• If the size of logical address space is 2 to the power of m, and a page size is 2 to the power of n addressing units, then the high order            bits of a logical address designate the page number, and the          low order bits designate the page offset.
