| comp., MS | data link | link danych (A connection between any two devices capable of sending and receiving information, such as a computer and a printer or a main computer and a terminal. Sometimes the term is extended to include equipment, such as a modem, that enables transmission and receiving. Such devices follow protocols that govern data transmission) |

| comp., MS | Data Link Control | DLC (An error-correction protocol in the Systems Network Architecture (SNA) responsible for transmission of data between two nodes over a physical link. Supported by Microsoft Windows NT and Windows 2000, DLC is designed to provide access to IBM mainframe computers and to Hewlett-Packard printers connected to the network) |

| comp., MS | data-link layer | warstwa linku danych (Layer two of the OSI model. A layer that packages raw bits from the physical layer into frames (logical, structured packets for data). This layer is responsible for transferring frames from one computer to another, without errors. After sending a frame, the data-link layer waits for an acknowledgment from the receiving computer) |
| comp., MS | High-level Data Link Control | HDLC (A protocol for information transfer adopted by the ISO. HDLC is a bit-oriented, synchronous protocol that applies to the data-link (message-packaging) layer (layer 2 of the ISO/OSI reference model) for computer-to-microcomputer communications) |
| comp., MS | Link Data Sources Wizard | Kreator łączenia źródeł danych (A wizard dialog title to create a linked data source, where you can link multiple data sources into one single data source such as two different tables in a SQL database) |
| comp., MS | synchronous data link control | SDLC (A type of link service used for managing synchronous data transfer over standard telephone lines (switched lines) or leased lines. The data transmission protocol most widely used by networks conforming to IBM's Systems Network Architecture (SNA). SDLC is similar to the HDLC (High-level Data Link Control) protocol developed by the International Organization for Standardization (ISO)) |
