A brief history about CRLF (Carriage Return – Line Feed)

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.

In Windows applications, a new line is normally stored as a pair of characters: carriage return (CR) and line feed (LF). The character pair bears some resemblance to the typewriter actions of setting a new line. In Unix applications, a new line is normally stored as a LF character. Macintosh applications use only a CR character to store a new line.
