DPI stands for which phrase?

• A. Data Processing Index
• B. Dots Per Inch
• C. Display Pixel Information
• D. Digital Page Increment

Answer: (B)

DPI measures how densely an image is built from individual units in one inch, which is a direct way to describe resolution. The phrase dots per inch is the best choice because it literally counts the tiny dots that make up the print or image within each inch, so a higher DPI means more detail and smoother edges. The other options don’t describe this density: they aren’t standard terms for measuring how many building blocks fit in an inch, and they don’t convey the idea of resolution the way dots per inch does. (Note: on screens you’ll often see pixels per inch used, but the same idea of density applies.)
