WebData link layer; The data link control layer consists of the elements that provide an interface to the hardware. it elements supply support for specific data link protocols, such as Synchronous Data Link Control. it provides a common link to the elements in the path control layer. It is common to all Personal Communications implementations. In the Internet Protocol Suite (TCP/IP), OSI's data link layer functionality is contained within its lowest layer, the link layer. The TCP/IP link layer has the operating scope of the link a host is connected to, and only concerns itself with hardware issues to the point of obtaining hardware (MAC) addresses for locating … See more The data link layer, or layer 2, is the second layer that of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the See more The data link layer is often divided into two sublayers: logical link control (LLC) and media access control (MAC). Logical link control sublayer The uppermost sublayer, LLC, multiplexes protocols running at the top of the data link layer, and … See more In addition to framing, the data link layer may also detect and recover from transmission errors. For a receiver to detect transmission errors, the sender must add redundant information as an error detection code to the frame sent. When the receiver obtains a … See more The data link provides for the transfer of data frames between hosts connected to the physical link. Within the semantics of the OSI network architecture, the protocols of the data link layer respond to service requests from the network layer, and perform their … See more The services provided by the data link layer are: • Encapsulation of network layer data packets into frames • Frame synchronization • In the logical link control (LLC) sublayer: See more • ARCnet • ATM • Cisco Discovery Protocol (CDP) See more • ALOHAnet § ALOHA protocol • ODI • NDIS • SANA-II – Standard Amiga Networking Architecture, version 2 See more WebJul 8, 2024 · SLIP is a very simple layer 2 protocol that provides basic frames for IP Datagrams, while the Point-to-Point Protocol is a more sophisticated, fully-featured data link layer protocol that provides frames as well as additional features that enhance security and performance.
