Question

The figure below shows a black and white image with a resolution of 720×504. Identify how much memory (in bits) will be occupied by this image in the hard drive of your computer, if it is stored. (2 marks)

​

Answer 1

362880

Step-by-step explanation:

In black and white images each pixel is 1 bit. You need to first find the total number of pixels, to do this you multiply the width and length of the picture (720x504) and you will get 362880. From there you would multiply the amount of pixels by how many bits each pixel is. In this case, since its black and white you multiply it by 1, which is 362880.
