The term "resolution" refers to

a.)the number of pixels that describe an image.
b.)size of a digital image the printer produces.
c.)number of pixels you see on your computer monitor.

Options A and C can get you confused. We can choose option A if our argument is based entirely on digital images. The correct answer, however, is  C: Number of pixels you see on your computer monitor.

Resolution describes the clarity and sharpness of a picture that can be measured by the number of pixels contained on a display monitor. It can be expressed by the number of horizontal (width) and vertical pixels (height) represented by a screen. The clarity and sharpness are always dependent on the resolution and size of the monitor.
