Bitmap image | Bitmap images are stored as a series of pixels. |
Pixel | A pixel is a single point in a graphic image with an assigned colour. Many of them on a screen are assigned a colour in a specific place to recreate a bitmap image. |
Color Depth
Color depth is either the number of bits used to indicate the color of a single pixel, in a bitmap image, or the number of bits used for each color component of a single pixel. This means the number of bits needed to code an image. For example an image will only need 2 bit color depth for black and white, such as the following image...

although if an image has 24 bit color depth, it can code up to 16777216 colors, such as the following image...
Resolution
Resolution is determined by the height and width of an image file, for example:
This square has a total of 10000 pixels because 100 * 100 is 10,000.
The image above is the same image but with twice the magnification of the first. You should start to see pixels of the image appear.
