The monitor works with a 16-color palette at 640×400 pixels. It takes 1250 KB to encode the image. How many pages of video memory it takes.
In order to calculate how many memory pages the encoding will take:
16 = 42 —> 4 bits for one pixel
Monitor – One page of video memory:
640 * 400 * 4 = (640) * (1600) = (5 * 2 ^ 7) * (25 * 6 ^ 2) = 125 * 13 ^ 2 (bits) = 125 (Kbytes)
Image:
1250: 125 = 10 (pages)
Answer: coding will take 10 pages.
