Dpi refers to which measurement in printing?

• A. The number of dots per inch printed
• B. The number of bytes per second of data transfer
• C. The color depth per pixel
• D. The number of frames per second in video

Answer: (A)

DPI is a measure of printing resolution—the number of dots a printer places in one inch. It tells you how densely ink dots are laid down, so more dots per inch produce finer detail and smoother color transitions in the printed image. If you print at a higher DPI, the result generally looks crisper, provided the paper and ink can support it and the image has enough digital detail to fill those dots. This concept is about printed output, not data transfer speed, color depth per pixel, or video frame rate, which is why those other options don’t describe printing resolution.
