What is the term for the suffix added to a file name that indicates the file type?

• A. Label
• B. Marker
• C. Extension
• D. Identifier

Answer: (C)

The correct term for the suffix added to a file name, which indicates the file type, is "extension." File extensions play a crucial role in file management and usage, as they provide essential information about the type of file and the application needed to open it. For instance, a file with a ".docx" extension is recognized as a Microsoft Word document, while a file with a ".jpg" extension is identified as a JPEG image. This allows operating systems to associate the appropriate software for managing and editing the file, enabling users to efficiently interact with various types of data. The clarity that file extensions provide helps avoid confusion about file formats and functionalities.
