What is the minimum amount of video memory required to store a graphic image that occupies a 512X512 dots screen area, where each dot can have one of 256 colors?
The image, which occupies 512×512 pixels, contains 262144 pixels.
One point, which can have one of 256 colors, occupies 8 bits in memory.
To find the minimum memory size, you need to multiply the total number of points by the memory size that one point occupies:
262144 * 8 = 2097152 bits = 262144 bytes = 256 kilobytes.
