Question

which phrase best describes the concept of a file type? (1 point) the files extension the quantity of pixels the files memory dimensions the reduction in digital footprint

Explanation:

A file type is identified by its extension. For example, a .docx file is a Microsoft Word document, a .jpg is an image file. The extension tells the operating system and applications what kind of data is in the file and how it should be processed. The quantity of pixels relates to image resolution (not file type), memory dimensions are about how much space a file takes (not its type), and reduction in digital footprint is about minimizing data storage/transmission (not file type).

Answer:

the file's extension
