11) Reusing PCBs of destroyed processes instead of freeing up the data structures eliminates the overhead of dynamic memory management but is likely to use more memory. Assume the following: The number of processes to be created and destroyed over a period of time is 10,000. The average number of processes coexisting at any given time is 100. The maximum number of processes coexisting at any given time is 600. Allocating and freeing a PCB take the same amount of time. (a) How many memory operations (allocate or free) will be performed without PCB reuse? (3 points) (b) How many memory operations (allocate or free) will be performed with PCB reuse? (3 points) 11) Reusing PCBs of destroyed processes instead of freeing up the data structures eliminates the overhead of dynamic memory management but is likely to use more memory.
