CASE STUDY #4 - MEMORY ALLOCATION IN DYNAMIC PARTITION AND RELOCATABLE DYNAMIC PARTITION

Load the following jobs into memory using dynamic partition and relocatable dynamic partition: (The memory size is 220k with allocated OS for 15k).

a. Job1 (100k)             f. Job6 (6k)

turnaround: 3                turnaround: 1

b. Job2 (10k)               g. Job7 (25k)

turnaround: 1                turnaround: 1

c. Job3 (35k)               h. Job8 (55k)

turnaround: 2                turnaround: 2

d. Job4 (15k)               i. Job9 (88k)

turnaround: 1                turnaround: 3

e. Job5 (23k)               j. Job10 (100k)

turnaround: 2                turnaround: 3

*turnaround – how long it will stay in the memory.

*apply compaction if only if the incoming jobs has no other block to allocate that will fit their sizes.
