File System Concepts for Operating Systems

1. What is the purpose of the File Allocation Table (FAT) in FAT file systems?

To store user passwords

To track which disk clusters are used or free

To compress file data

To manage user permissions

2. Which file system feature prevents multiple write operations to the same file simultaneously?

Compression

Locking mechanism

Encryption

Journaling

3. What is the difference between absolute and relative paths in file systems?

Absolute paths start from the root; relative paths start from the current directory

Absolute paths are shorter; relative paths are longer

Absolute paths use forward slashes; relative paths use backslashes

Absolute paths are for directories; relative paths are for files

A text summary of a file's contents

An integer that references an open file within a process

The file's extension or type

A user-written comment about a file

5. What is the primary advantage of using a hierarchical file system?

It increases file transfer speed

It organizes files logically and makes them easier to locate

It eliminates the need for backups

It reduces disk space usage

6. What does the 'path' refer to in a file system?

The physical location of a file on the disk

The sequence of directories leading to a file or folder

The size of a file in bytes

The time a file was last modified

7. Which of the following is a function of the file system's journal?

Store user login information

Track metadata changes for recovery after system failures

Compress files to save space

Monitor network traffic

8. In a file system, what does the term 'mount' refer to?

Compressing a file for storage

Making a storage device accessible within the directory tree

Creating a backup of files

Encrypting file permissions

9. What is the primary function of a file system in an operating system?

Manage memory allocation

Organize, store, and retrieve data on storage devices

Control CPU scheduling

Handle network communication

10. What is fragmentation in the context of file systems?

The process of breaking files into smaller parts

Scattered placement of file data across non-contiguous disk blocks

The deletion of unused files

The encryption of file data

11. A symbolic link (soft link) in a file system is best described as:

A direct copy of the original file

A pointer or reference to another file or directory

A backup of the original file

A compressed version of a file

12. What does the chmod command do in Unix/Linux file systems?

Changes file ownership

Modifies file permissions

Creates a new directory

Displays file contents

13. Which permission allows a user to read the contents of a file?

Execute (x)

Write (w)

Read (r)

Modify (m)

14. What is an inode in Unix-like file systems?

A symbolic link to another file

A data structure storing file metadata and disk block pointers

A file permission setting

A directory entry name

15. In most file systems, what does the file extension indicate?

The file's creation date

The file's size in kilobytes

The type or format of the file

The user who owns the file

16. What does the root directory represent in a hierarchical file system?

The topmost directory from which all other directories branch

The location where temporary files are stored

A hidden system directory

The user's home folder

17. Which of the following best describes a directory in a file system?

A container that holds files and other directories

A type of executable program

A temporary storage location in RAM

A backup copy of a file

18. Which file system is commonly used on Linux distributions?

FAT32

NTFS

Ext4

HFS+

19. What is a hard link in a file system?

A reference that points to the inode of a file

A network connection to a remote file

A temporary shortcut to a file

A password-protected file access method

20. In permission notation like '755', what does each digit represent?

Owner, group, and others permissions

Read, write, and execute in binary

File size in kilobytes

Year, month, and day created
