D) secondary storage

Question

Quizplus · Accepted Answer

The other components listed (display generator circuitry, software stored in ROM, video processor, and font tables) all relate to the creation and manipulation of images on the screen. RAM, on the other hand, is necessary for temporarily storing the data needed to create those images. Therefore, RAM is the best choice for the missing component. Secondary storage like D) may be used to store video files, but is not essential to the functioning of the video controller itself. Display pixels like C) are the result of the video controller's output, not a component of the controller itself.
