Question: 1 / 400

If 3 bits of memory are available, what is the greatest number of shades of gray that are present in the scan converter?

4

8

In digital imaging, the number of shades of gray that can be represented is determined by the number of bits used for each pixel. Each additional bit doubles the number of possible gray shades.

With 3 bits of memory available, you can represent 2^3 = 8 different shades of gray. This is because each bit can have 2 possible values (0 or 1), and with 3 bits, there are 2x2x2 = 8 possible combinations. Therefore, the correct answer is B.

Options A, C, and D are incorrect because they do not accurately reflect the number of shades of gray that can be represented with 3 bits of memory.
