The amount of video memory is 2.5 MB, the color depth is 16 bit, the screen resolution is 640 * 480

The amount of video memory is 2.5 MB, the color depth is 16 bit, the screen resolution is 640 * 480, what is the maximum number of pages that can be placed under these conditions?

Let us determine what total number of pixels the screen produces when we know from the task condition that its resolution is 640 * 480:

640 * 480 = 307200.

Let us determine how much memory in bits is required when from the setting condition we know that the color depth is 16 bits:

307200 * 16 = 4915200.

Let’s translate the volume we found in kilobytes:

1 bit – this will be 8 bytes;

1 KB – this will be 1024 bytes;

4915200: 8: 1024 = 600.

Memory size in Kbytes:

2.5 * 1024 = 2560.

Then pages:

2560: 600 = 4.2 (6).

Answer: 4 full pages.
