Right now you’re looking at a computer screen, reading this definition. The color scheme of the page, the individual letters, and the negative space surrounding those letters are all composed of pixels–tiny little electronically toggled points of color and light on the screen.
A pixel is the smallest addressable element in a display device. If you’ve ever put your eye right up to the surface of a television screen or monitor you’ve seen the tiny little dots (on older televisions and CRT displays) or rectangles (on modern HDTV or LCD monitors) that make up the display lattice. Those individual dots/squares are the pixels the display devices is capable of presenting to you. Every image you see on the screen is composed of hundreds of thousands (and in the case of modern HD displays, millions) of those individual pixels rendered in varying shades of color.
