A disk uses a block size of 4\,KB. A file of 10\,250\,bytes is to be stored. (a) Using contiguous allocation, how many blocks are required and what total disk space is occupied? (b) Using linked allocation where each block reserves 64\,bytes for a pointer, how many blocks are required and what total disk space is occupied? (c) Which method results in less wasted space (internal fragmentation) and by how many bytes?

Answer Options

A. Both methods use 12,288 bytes; linked allocation wastes 1,920 bytes and saves 128 bytes of internal fragmentation compared with contiguous allocation.
B. Both methods use 12,288 bytes; linked allocation wastes 1,792 bytes and saves 256 bytes of internal fragmentation compared with contiguous allocation.
Correct Answer C. Both methods use 12,288 bytes; linked allocation wastes 1,846 bytes and saves 192 bytes of internal fragmentation compared with contiguous allocation.
D. Both methods use 12,288 bytes; linked allocation wastes 2,048 bytes and saves 0 bytes of internal fragmentation compared with contiguous allocation.
Correct Answer
C
Correct Option:
Both methods use 12,288 bytes; linked allocation wastes 1,846 bytes and saves 192 bytes of internal fragmentation compared with contiguous allocation.
