Neco 2021 Data Processing Question 29
Practice objective / multiple choice question 29 from the 2021 Neco Data Processing examination.
In a hierarchical file system, each directory entry occupies 64 bytes. The root directory contains 4 sub‑directories. Each of these sub‑directories contains 6 files and 2 sub‑sub‑directories. Every sub‑sub‑directory contains 3 files. All files are 2{,}048 bytes long and the disk uses a block size of 1{,}024 bytes (so each file occupies exactly two blocks). Ignoring block fragmentation for directories, calculate the total disk space used for storing all files and all directory entries, and give the answer in kilobytes (1 KB = 1{,}024 bytes).
