Problem Statement
Explain what an inode is in a Unix-style file system and what information it holds.
Explanation
An inode is a data structure used in many Unix-style file systems to represent a file or directory. It holds metadata such as the owner, permissions, file size, creation/modification/access times, and pointers to the data blocks where the file’s contents reside. The inode number is an index into an inode table used by the OS. Knowing inodes helps you understand underlying file system implementations. :contentReference[oaicite:2]{index=2}
