Question: This diagram shows memory configuration under dynamic partitioning after several placements and swapping-out operations have been carried out. Addresses go from left to right; gray

  • This diagram shows memory configuration under dynamic partitioning after several placements and swapping-out operations have been carried out. Addresses go from left to right; gray areas indicate blocks occupied by processes; white areas indicate free memory blocks. The last process placed is 2-Mbyte and is marked with an X. Only one process was swapped out after that.

4M


1M

X

5M


8M


2M


4M


3M


  • What was the maximum size of the swapped-out process?
  • What was the size of the free block just before it was partitioned by X?
  • A new 3-Mbyte allocation request must be satisfied next. Indicate the intervals of memory where a partition will be created for the new process under the following four placement algorithms: best-fit, first-fit, next-fit, worst-fit. For each algorithm, draw a horizontal segment under the memory strip and label it clearly.
