state and explain FIVE basic disk-based file system operation
Answer Posted / Sonali Srivastava
1. File creation: The process of creating a new file on the disk, including allocating space for the file, setting up its directory entry, and initializing its contents.
2. File deletion: Removing a file from the disk, which involves deallocating its allocated space and updating its directory entry to reflect its absence.
3. File renaming: Changing a file's name while keeping its contents and location intact, which typically requires updating its directory entry with the new name.
4. File copying: Duplicating a file from one location on the disk to another, including allocating space for the copied file and transferring its data.
5. File movement (or relocation): Moving a file from one location on the disk to another without creating a duplicate, which involves updating its directory entry with the new location.
