The amount of pixels contained in a graphics system's frame buffer is referred to as,
Resolution
Screen Size
Screen Color
None of the above mentioned
Correct Answer :
A. Resolution
A screen resolution can be determined by the number of pixels. If a display system contains good quantity of pixels, it means the visibility of the screen will be highly clear.
