What term refers to the endings of file names that indicate the format for how the underlying bits are organized?

• A. Hexadecimal Number System
• B. RGB
• C. White represented RGB in 32Bit Hex
• D. file extensions

Answer: (D)

File extensions are the endings of file names that indicate the format for how the data inside is organized. The extension comes after the last dot, like .txt, .jpg, or .pdf, and it tells the operating system and programs what kind of content is inside and how to interpret it. This helps determine which application should open the file and how to read its data. For example, .txt signals plain text, while .jpg and .png denote image formats. The other ideas described—a base-16 number system, a color model, or a confusing phrase about RGB in 32-bit hex—don’t describe how file names indicate their format, so they aren’t the correct term.
