Looking for Definition of DLC or what DLC stands for?

Data Link Control (DLC) in the OSI networking model is the data link layer’s functionality. Network interface cards have a DLC address that recognizes each card; Ethernet and other types of cards, for example, have a 48-bit MAC address incorporated into the firmware of the cards as they are made.

A network protocol with the name Data Link Control still exists. It is similar to protocols like TCP / IP or AppleTalk that are best known. IBM SNA mainframe computers and peripherals and compatible equipment use DLC as a transport protocol. It is usually used in computer networking to connect with network-attached printers, computers, and servers, e.g., HP on their JetDirect print servers. Since it was used heavily before Windows 2000, Windows XP versions onwards do not have DLC support.
