The second layer of the OSI reference model. This layer puts messages together and manages their flow between computers.
Layer 2 of the OSI reference model. Provides reliable transit of data across a physical link. The data-link layer is concerned with physical addressing, network topology, line discipline, error notification, ordered delivery of frames (logical groupings of information), and flow control. The IEEE divided this layer into two sublayers: the MAC sublayer and the LLC (logical link control) sublayer. Sometimes called the link layer.
Layer 2 in ASAI protocol stack, which controls data transmission across the link. ASAI specifies several different data-link layer protocols that can do this.
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.
The second of seven layers of the International Standards Origanization's Open Systems Interconnection (ISO/OSI) model for computer-to-computer communications. The data-link layer validates the integ ... more
OSI Layer 2, which defines how data is packetized and transmitted to and from each network device. It is divided into two sublayers: medium access control and logical link control.
