A system uses variable partition memory management with the following free memory blocks (in KB):
Block 1: 100, Block 2: 500, Block 3: 200, Block 4: 300, Block 5: 600
Four processes arrive in the following order with their memory requirements (in KB):
P1: 212, P2: 417, P3: 112, P4: 426
Using the Best Fit allocation strategy, determine which block each process is allocated to and how much total internal fragmentation remains at the end of all allocations.
Show answerHide answer
Correct answer: (C) P1 → Block 4, P2 → Block 2, P3 → Block 3, P4 → Block 5; Total internal fragmentation = 433 KB
