In telecommunications, an acknowledge character (ACK) is a transmission control character transmitted by the receiving station as an acknowledgement, i.e. an affirmative response to the sending station: this is defined in Federal Standard 1037C. In the ASCII code, the ACK character is 0x06 (hexadecimal), or ^F. "ACK" is also used as a slang abbreviation in internet forums and chats (mainly technology) for "Understood".
