Line feed
In computing, line feed is one of control characters in ASCII that is used to move printer or display one line down. Line feed often follows carriage return to indicate a new line. In some envrionments, carriage return is omited and only line feed indicates a new line.In ASCII, it has a decimal numeral code, 10.
The term derives from the fact that when this control character was sent to early printers, it would physically move down a line, similar to the operation of a typewriter.
