2. Suppose that three concurrent processes exist in a system, as described in the following table: Process Threads within the process T11,T12,T13, T14 Suppose that T is running when the time quantum expires. [10 marks total] (a) If the threads are implemented entirely at the user level, with no support from the operating system, explain what units could be dispatched next? [5 marks] (b) If the threads are supported by the operating system, explain what units could be dispatched next? [5 marks] 2.
