Operating Systems - Inode Structure - File Metadata & Block Pointers

Which of the following statements about inodes is INCORRECT?

AInodes store pointers to data blocks that hold the file's actual content.

BAn inode contains the file's name and its metadata such as permissions and timestamps.

CMultiple directory entries can point to the same inode, enabling hard links.

DInodes are fixed-size structures that do not store file names.

Step-by-Step Solution

Step 1: Clarify inode contents
Inodes store metadata (permissions, timestamps, size) and pointers, but NOT file names.
Step 2: Confirm pointer role
Inodes contain direct and indirect pointers to data blocks.
Step 3: Understand hard links
Multiple directory entries can reference the same inode, enabling hard links.
Step 4: Recognize inode size
Inodes are fixed-size and do not store variable-length file names.
Final Answer:
Option B -> Option B
Quick Check:
File names are stored in directory entries, not inodes [OK]

Quick Trick: Inode = metadata + pointers; directory entry = file name + inode number

Common Mistakes:

MISTAKES

Trap Explanation:

PITFALL

Option A is a common misconception that inodes contain file names. Options B, C, and D correctly describe inode properties.

Interviewer Note:

CONTEXT
