Neco 2022 Computer Studies Question 23
Practice objective / multiple choice question 23 from the 2022 Neco Computer Studies examination.
A disk uses a block size of 4\,KiB. Four files occupy the following byte sizes: File A - 6,500 bytes, File B - 12,300 bytes, File C - 3,200 bytes, File D - 9,800 bytes. (a) How many disk blocks are required in total? (b) What is the total wasted space (unused bytes within allocated blocks)? (c) If the average seek time is 8 ms, rotational latency is 4.2 ms, and transfer time per block is 0.5 ms, compute the total time to read all files sequentially (assume one seek and one rotational latency per file, no caching). Give the answer in milliseconds rounded to one decimal place.
