The purpose and function of data link layer
WebbPurpose. The internet layer has three basic functions: For outgoing packets, select the next-hop host and transmit the packet to this host by passing it to the appropriate link layer implementation; For incoming packets, capture packets and pass the packet payload up to the appropriate transport layer protocol, if appropriate.

WebbIt breaks down the functions involved in sending data over the Internet into seven layers. Each layer has some function that prepares the data to be sent over wires, cables, and radio waves as a series of bits. The seven layers of the OSI model are: 7. ... Data link layer: Handles communications between devices on the same network. Webb4 feb. 2024 · TCP/IP has four layers. OSI model, the transport layer is only connection-oriented. A layer of the TCP/IP model is both connection-oriented and connectionless. In the OSI model, the data link layer and physical are separate layers. In TCP, physical and data link are both combined as a single host-to-network layer.
WebbWe say that the data link layer is providing a service to the network layer by transporting its data in frames across the link. The TCP/IP model We can now start to build our layered model from the bottom up. You can see that the data link layer is just the first, or bottom, layer of a layered model called the TCP/IP model. WebbThe data-link layer is the software closest to the hardware (physical layer). Thus, it includes, among other functions, any software needed to control the hardware. Bridging also occurs at this layer to allow networks interconnected with different physical layer protocols (e.g., Ethernet LAN and an 802.11 LAN) to interconnect. Like physical ...
