Question 39 NECO • 2023 • DATA_PROCESSING • objective

A disk uses blocks of \(4096\) bytes. A file of size \(10\,000\) bytes is stored.\n\n(i) With contiguous allocation, how many blocks are allocated and what is the total storage used (including internal fragmentation)?\n\n(ii) With linked allocation, each block stores an \(8\)-byte pointer to the next block. Assuming the pointer occupies part of the block, how many blocks are needed and what is the total storage used? Also compute the amount of wasted space (unused data bytes) for each method.\n\nWhich method results in less wasted space?

Answer Options

A. Linked allocation wastes less space (2,300 bytes) than contiguous allocation (2,350 bytes).
Correct Answer B. Linked allocation wastes less space (2,264 bytes) than contiguous allocation (2,288 bytes).
C. Contiguous allocation wastes less space (2,264 bytes) than linked allocation (2,288 bytes).
D. Both methods waste the same amount of space (2,276 bytes).
Correct Answer
B
Correct Option:
Linked allocation wastes less space (2,264 bytes) than contiguous allocation (2,288 bytes).
