It stands for Carraige Return Line Feed. It starts a new line when you are outputting something, like in a Message box.
When you access a webpage, the web browser (client) sends a HTTP request to the web server. The web server processes the request and sends a HTTP status code along with any additional content if needed as a response.You can observe this process by using a packet tracer program or send the HTTP requests yourself from a terminal session:Connect to a web server at port 80 using a Telnet client.Send a GET / HTTP/1.1 followed by a CrLf (enter/return key), then a Host: where is the hostname. After that, send the request by entering two more CrLf's.
In computer programming, CRF might stand for Change Request Form. CrLf stands for Carriage Return - Line Feed, or the control character combination created when the enter key is pressed under a Microsoft operating system.

It performs conversion between different codesets, like ASCII and EBCDIC, and fixes the line-end incompatiblity between different systems (WinDos: CRLF, Unix: LF, Macintosh: CR)
It stands for carriage return/line feed. The names are a holdover from typewriter days. They are two control codes in ASCII (American Standard Code for Information Interchange); cr returns the cursor to the beginning of the line, lf moves the cursor down to the next line.
In PHP, you can create a Windows-style CRLF line break using the string "\r\n". However, it is usually sufficient, easier to handle, and sometimes even necessary to omit the CR, meaning that you can just use "\n". Although the line break will just count as white space for HTML (use can echo "<br>" to create a line break in HTML), it is useful for <pre>formatted text, textareas, or for outputting a formatted non-HTML text response.
A text file is a file containing human readable characters organized into records (lines) that are separated by the new-line character. The run-time library parses on this basis, and converts carriage-return/line-feed sequences to and from the new-line character as needed. (In a Windows/DOS environment.)A binary file is a file containing any characters. There is no file based delimiting - all record distinctions are made by the program. (The exception to this is in the IBM (and other?) family of MainFrame computers where logical record sizes are declared in the DCB, and the file is not processed in stream mode.)
The main purpose of SMTP is to deliver messages to user's mailboxes. A very similar service provided by some hosts is to deliver messages to user's terminals (provided the user is active on the host). The delivery to the user's mailbox is called "mailing", the delivery to the user's terminal is called "sending". Because in many hosts the implementation of sending is nearly identical to the implementation of mailing these two functions are combined in SMTP. However the sending commands are not included in the required minimum implementation (Section 4.5.1). Users should have the ability to control the writing of messages on their terminals. Most hosts permit the users to accept or refuse such messages. The following three command are defined to support the sending options. These are used in the mail transaction instead of the MAIL command and inform the receiver-SMTP of the special semantics of this transaction: SEND <SP> FROM:<reverse-path> <CRLF> The SEND command requires that the mail data be delivered to the user's terminal. If the user is not active (or not accepting terminal messages) on the host a 450 reply may returned to a RCPT command. The mail transaction is successful if the message is delivered the terminal. SOML <SP> FROM:<reverse-path> <CRLF> The Send Or MaiL command requires that the mail data be delivered to the user's terminal if the user is active (and accepting terminal messages) on the host. If the user is not active (or not accepting terminal messages) then the mail data is entered into the user's mailbox. The mail transaction is successful if the message is delivered either to the terminal or the mailbox. SAML <SP> FROM:<reverse-path> <CRLF> The Send And MaiL command requires that the mail data be delivered to the user's terminal if the user is active (and accepting terminal messages) on the host. In any case the mail data is entered into the user's mailbox. The mail transaction is successful if the message is delivered the mailbox. The same reply codes that are used for the MAIL commands are used for these commands.
