Fragmentation Types List-I (Fragmentation Class) A. Internal Fragmentation B. External Fragmentation C. Compaction D. Paging Solution List-II (Root Cause / System Condition) Memory block allocated to a process is larger than requested Total free memory is sufficient, but it is split into small, non-contiguous blocks Shuffling memory contents to place all free blocks together in one large chunk Eliminates external fragmentation by allocating fixed-size blocks

A-1, B-2, C-3, D-4 Explanation: A. Internal Fragmentation 1 Explanation: Internal fragmentation occurs when the memory block allocated to a process is slightly larger than the memory requested by it, leaving unused space inside the allocated block. B. External Fragmentation 2 Explanation: External fragmentation happens when total free memory is sufficient to satisfy a request, but it is split into small, non-contiguous blocks scattered across the memory. C. Compaction 3 Explanation: Compaction is a strategy to overcome external fragmentation by shuffling memory contents to place all free blocks together into one large contiguous chunk. D. Paging Solution 4 Explanation: Paging eliminates external fragmentation entirely by breaking physical memory into fixed-size blocks (frames) and logical memory into blocks of the same s
