A bit is the smallest piece of information used in creating a graphical representation on a screen. A bit can contain the value of of 0 or 1. You can also think of it as TRUE OR FALSE.
These images we are making are called 1-bit monochrome images, which means each space on the screen can either be TRUE (there is black) or FALSE (there is no black).
This is also called a binary image because there are only 2 choices: The color (black) is either ON or OFF. Any two colors can be used as only there are only two.
The space of the screen is broken up into grid we can't see- the smallest units of this grid are called pixels. EACH PIXEL (or PIcture ELement) IS STORED AS A SINGLE BIT- either a 0 or a 1. Binary images have only two possible values for each pixel.
The more color bits there are in an image file, the more gradations of color.
An 8-bit image can display 256 possible colors.

Bill Gosper's Glider Gun in action—a variation of Conway's Game of Life. This image was made by using Life32 v2.15 beta, by Johan G. Bontes.
It uses only 2 colors- 1 BIT: on or off.
