File System MCQs

1. The fundamental purpose of file management is:

a) CPU scheduling b) Organizing data on storage devices c) Memory allocation d) Process synchronization

Correct Answer: b) Organizing data on storage devices

Explanation:
File management systems provide structured organization, naming, storage, retrieval, and protection of data on persistent storage devices.

2. A file extension typically indicates:

a) File size b) File type c) File permissions d) File location

Correct Answer: b) File type

Explanation:
File extensions (like .txt, .jpg) help identify the file format and what programs can open it, though they don't guarantee the actual content type.

3. Which is NOT a file attribute?

a) Name b) Size c) Priority d) Creation time

Correct Answer: c) Priority

Explanation:
Standard file attributes include name, size, type, location, protection, time/date (creation, modification), but not priority which is a process attribute.

4. Random access is supported by:

a) Magnetic tape b) Hard disk c) Both d) Neither

Correct Answer: b) Hard disk

Explanation:
Hard disks support direct access to any block, while tapes are sequential-access devices requiring linear traversal to reach specific data.

5. Sequential access is most suitable for:

a) Databases b) Log files c) Random queries d) None

Correct Answer: b) Log files

Explanation:
Log files are typically written and read sequentially (append-only), making sequential access ideal. Databases require random access for efficient queries.

6. Indexed allocation uses:

a) Linked lists b) Bitmaps c) Index blocks d) Page tables

Correct Answer: c) Index blocks

Explanation:
Indexed allocation stores pointers to all file blocks in a dedicated index block, allowing both sequential and direct access without external fragmentation.

7. A single-level directory has:

a) No subdirectories b) Multiple users c) Shared files d) All of the above

Correct Answer: a) No subdirectories

Explanation:
Single-level directory systems have all files in one directory with no hierarchy, leading to naming conflicts and poor organization as files increase.

8. Absolute pathnames specify:

a) Relative location b) Full path from root c) File size d) Permissions

Correct Answer: b) Full path from root

Explanation:
Absolute paths (like /home/user/file.txt) start from the root directory, while relative paths are specified from the current working directory.

9. Acyclic graph directories allow:

a) Cycles b) File sharing c) No subdirectories d) None

Correct Answer: b) File sharing

Explanation:
Acyclic graph structures permit multiple directory entries (links) to reference the same file, enabling sharing while preventing infinite loops.

10. Mounting makes a file system:

a) Hidden b) Available at a directory c) Read-only d) Smaller

Correct Answer: b) Available at a directory

Explanation:
Mounting attaches a file system to the directory tree at a specified mount point, making its contents accessible through that directory path.

11. NFS enables:

a) Local file access b) Network file sharing c) Memory management d) None

Correct Answer: b) Network file sharing

Explanation:
The Network File System (NFS) protocol allows remote file systems to be accessed over a network as if they were local.
