2 There are 3 resources and 3 processes in a system. Availability Table Resources The quantities of resources requested by the processes are as follows: Request Table: Res A Res C The resources allocated by the system are as follows: Allocation Table: Res A Res C Is the system in a deadlock? If yes, then what are the process(es) that need to be pre-empted and in what order, to ensure that deadlock is overcome? 3. Consider a set of four tasks. These tasks have their arrival times, execution times and dead-lines shown in the table below. The times are shown here as multiples of the time unit. The schedule is revised after arrival of every task or if 10 units of time have elapsed after the last revision. Prepare as earliest dead-line first sched- ule for this opcrational scenario. Time of Time required to cxecute Time dead line of 35 120 75 100 25 10
