  • File attributes and metadata
  • Cache memory structure
5. In which file allocation method does each file have its own index block?
  • Contiguous allocation
  • Indexed allocation
  • Linked allocation
  • Hash-based allocation
6. What is the purpose of a directory in a file system?
  • To store temporary files

10. What is the primary advantage of indexed file allocation?
  • Sequential access efficiency
  • Easy direct access to file blocks
  • Reduced storage overhead
  • Simplified file management
11. What does a file system journal track?
  • User access history
  • Changes to files and directories
  • Physical storage locations
  • File permission updates
12. Which directory structure allows files to have multiple parent directories?
  • Single-level directory

  • Graph directory structure
  • Multi-level directory
13. The FAT file system is primarily used in:
  • Linux-based systems
  • Windows-based systems
  • macOS systems
  • Mobile devices only
14. A file extension is typically used to indicate:
  • File size
  • File permissions
  • File type
  • File owner
15. What is a superblock in a file system?
  • A block containing metadata about the file system
  • A block storing user data
  • A block used for caching frequently accessed files
  • A backup block for the root directory
16. The process of reducing file size without losing data is called:
  • Compression
  • Encryption
  • Clustering
  • Defragmentation
17. What type of access method is used when data is retrieved in the order it is stored?
  • Direct access
  • Indexed access
  • Sequential access
  • Random access
18. The NTFS file system is known for its support of:
  • Small file sizes only
  • Limited directory structures
  • Advanced security and large storage capacities
  • No journaling capabilities
19. The command used to list files and directories in a Unix-like system is:
  • mkdir
  • ls
  • rm
  • cp
20. A contiguous file allocation method is best suited for:
  • Random access
  • Sequential access
  • Multi-user environments
  • Large, fragmented storage systems
21. What is a key disadvantage of linked file allocation?
  • Complex directory management
  • Difficulty in accessing large files sequentially
  • Lack of direct access capability
  • Increased storage overhead
22. In Linux, the inode stores information about:

  • File metadata
  • Directory structure
23. Which of the following is not a valid file operation?
  • Create
  • Rename
  • Delete
  • Share
24. A RAID system primarily provides:

  • Windows operating systems
  • Unix-like operating systems
  • macOS operating systems
  • Embedded systems
27. A dangling pointer in file systems refers to:
  • A file that cannot be accessed due to broken links
  • A file that is hidden from the user
  • A corrupted directory structure
  • A file block without metadata
28. The process of reorganizing data on disk to reduce fragmentation is called:
