Each character is given a unique binary code
What is the relationship between the resolution of an image and a number of pixels
Higher resolutions images have more pixels
What does each pixel in a bitmap image contain
Information about the colour to be displayed
What are bitmap images made up of
Pixels in a grid
How are characters given a unique binary code in a computer system
Each character is assigned to a specific binary pattern
How does the number of pixels affect the resolution/quality of an image
More pixels= higher resolution and better quality images
