What does a file system do?

• A. Provides computing power
• B. Controls network access
• C. Is a type of RAM
• D. Organizes how data is stored and retrieved on storage devices

Answer: (D)

A file system is what organizes how data is stored and retrieved on storage devices. It provides a structured space of files and folders, storing metadata like file names, sizes, timestamps, and permissions, and it keeps track of where the actual data blocks reside on the disk. It handles allocating and freeing space, maps the logical view of a file to the physical locations on storage, and offers read and write operations to programs. It also defines how data is named and accessed, enabling navigation through directories and applying access rules. It's not about computing power—that's handled by the CPU. It's also not about controlling network access—that's part of the OS's network and security features. And it's not a type of RAM—RAM is volatile memory used by running programs, while the file system manages non-volatile storage.
