Final answer:
UNIX inodes and vnodes used by the Virtual File System (VFS) have a file representation structure. UNIX inodes are unique designators within a single file system, while vnodes represent files in both local and remote file systems within the VFS.
Step-by-step explanation:
The UNIX inodes and vnodes used by the Virtual File System (VFS) have a file representation structure. UNIX inodes are unique designators within a single file system, and they contain metadata about a file like permissions, owner, size, and timestamps. On the other hand, vnodes are unique file designators that represent files in both local and remote file systems within the VFS.
