Questions
1. If you are to add a new 10MB process in the memory, where could it possibly be added and
why?
2. What could be the size of the free block just before it was partitioned by X? Rationalize your
answer.
3. Would you suggest the provisioning of virtual memory in this configuration? Why or why not?

4. Is it possible to add a new 7MB process using the first-fit placement algorithm without swapping out any process? Why or why not?
5. A new process is requesting a 3MB allocation. Illustrate the possible memory configuration using a horizontal segmented memory strip (like the diagram above), where a partition will be created for the new process under the following placement algorithms: best-fit and first-fit. Label
your illustration clearly.

Memory Configuration: A computer implements a dynamic partitioning technique for memory
management. A number of allocation and swapping-out operations have been carried out while the
computer is up and running. The diagram below shows the computer's current memory
configuration/allocation. The addresses go from left to right. The gray areas represent blocks that are
occupied by running processes, while the white areas indicate free memory blocks. The last process
that was loaded into the memory is marked with a red X in the diagram, and its size is 2MB. Only one
process was swapped out after that.
