Final answer:
Scrolling is the term used for moving through document information on the computer monitor vertically or horizontally, whereas zooming refers to changing the document's magnification level.
Step-by-step explanation:
The term used for moving through document information on the computer monitor, either vertically or horizontally, is Scrolling. This is a common feature across various applications and devices, allowing users to navigate through long pages or wide documents without needing to view the entire content on one screen. For instance, when using a PDF viewer, one can scroll through pages using the mouse wheel, touch gestures, or keyboard arrows. On the other hand, Zooming refers to changing the magnification level of the document, making the text and images larger or smaller, but not moving through the document itself. Therefore, the correct answer to the student's question is A) Scrolling.
