In the previous problem, we saw that each color can be represented using $24$ bits of data. It$$s pretty easy to extend that idea to images. An image can be stored in a computer as a rectangular grid of pixels, each of which is assigned one color.

A QHD $($quad HD$)$ image has a resolution of $2560$ pixels horizontally by $1440$ pixels vertically. $($QHD is sometimes called $1440$p$,$ although technically a $1440$p image can have horizontal dimensions other than $2560$ pixels.$)$
