在内存的基本分配方法中会形成内部碎片和外部碎片。请问什么是内

4. 答案：

Internal Fragmentation – allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used.

External Fragmentation – total memory space exists to satisfy a request, but it is not contiguous.

Reduce external fragmentation by compaction ： Shuffle memory contents to place all free memory together in one large block.
