I remember when I used to teach Social Studies, specifically while I was student teaching, a student would come up to me and ask me a question to which I had no idea what the answer was.

IPCS Word(s) of the Day: Digital Zoom
Digital Zoom = Digital zoom is not really zoom, in the strictest definition of the term. What digital zoom does is enlarge a portion of the image, thus ‘simulating’ optical zoom.
