End of Line (EOL): CRLF

CRLF, /ker'l*f/, sometimes /kru'l*f/ or /C-R-L-F/, a carriage return (CR, ASCII 13) followed by a line feed (LF, ASCII 10). CR and LF are control characters or bytecode that can be used to mark a line break in a text file.

• CR = Carriage Return (\r, 0x0D in hexadecimal, 13 in decimal) — moves the cursor to the beginning of the line without advancing to the next line.

• LF = Line Feed (\n, 0x0A in hexadecimal, 10 in decimal) — moves the cursor down to the next line without returning to the beginning of the line.

• CRLF = A CR immediately followed by a LF (\r\n, 0x0D0A) - moves the cursor down to the next line and then to the beginning of the line.

Unix/Linux and new macOS use just line feed (CR) as its line terminator. While Windows/DOS and HTTP use CRLF to indicate the end-of-line (end-of-paragraph).
