Show answer & explanation
Correct answer: B. A-III, B-I, C-IV, D-II
Explanation
The boot block sits at the very start of the disk and holds the boot program plus the partition table, matching (III) (A-III). The super block stores filesystem-wide metadata such as the free block list and free inode list, matching (I) (B-I). The inode block holds one table entry per file recording that file's attributes such as size, permissions and pointers to its data blocks, matching (IV) (C-IV). The data block is where the actual OS, program and user files are stored, matching (II) (D-II). This gives A-III, B-I, C-IV, D-II, which is option (ii).More Database Management Systems questions
