Question

Which of the following best describes image resolution?

A. A document provided by a printer guaranteeing print quality
B. A measurement of information within a certain space
C. An action to reduce image size for printing purposes
D. An action to rotate an image

Answer 1

Image resolution best describes the amount of detail an image holds, which is measured in pixels per inch. A higher resolution means the image has more pixels, resulting in clearer and sharper details, especially when printed or viewed at a larger size.

Step-by-step explanation:

The term image resolution refers to the amount of detail an image holds and is typically measured in pixels per inch (PPI). A higher resolution means that more pixels are used to display the image, resulting in greater detail. This allows for the image to be seen clearly at a larger size or when printed without pixelation (where the image appears blocky). So, for the student's question, the best description of image resolution is:

B. A measurement of information within a certain space

This is because image resolution is indeed a measure of how much information a digital image contains within the defined space of the image itself, typically expressed by the count of pixels in each dimension (width and height).
