The inode is a data structure in the Linux file system. Select all of the following statements that are true (incorrect selections gain negative marks). Select one or more: 1. The inode data structure contains the file contents of each file. 2. Only one file name can correspond to each inode. 3. An inode is not unique for a file (per partition). For example, when we create a hard link for a file, we create a new inode for the same file. 4. A directory's inode stores in its datablocks a "directory file" with the inode number for each of the files and subdirectories under the directory. 5. When a file with 100 bytes is allocated a 4 kilobyte disk block, we have an example of internal fragmentation. 6. Each inode has a unique number (on a partition)
