Question
One technique for overcoming external fragmentation is __________ .Select one:A.compactionB.loadingC.relocationD.partitioning
Solution
The correct answer is A. Compaction. This technique is used to overcome external fragmentation. It works by moving all the occupied memory blocks to one end of the partition, thus leaving all the free memory together in one large block. This process can be time-consuming and requires that the jobs be relocatable.
