carriage return (CR) and line feed (LF).

Do you know what a typewriter is? Well, a typewriter is a mechanical device which was used last century to produce printed documents. :-)
After you have typed one line of text on a typewriter, you have to manually return the printing carriage to the left margin position and
manually feed the paper up one line.
