It is known that the video memory of a computer has a size of 512 kb. The display capacity is 640 by 480 pixels.

It is known that the video memory of a computer has a size of 512 kb. The display capacity is 640 by 480 pixels. How many screen pages will fit in video memory at the same time with a palette of 256 colors?

Let’s find the total number of pixels:
640 * 480 = 307200
Since with a given palette (256 bits) one pixel requires 1 byte of memory, we get the total size of the required memory: 307200 bytes.
Since the size of the video memory:
512Kb = 512 * 1024 = 524588 bytes
Then we get:
524588/307200 = 1.7
