Document Summary
Quiz 8 and 9 are on december 1. Final exam: thursday, december 14 at 4pm. Data-link layer has responsibility of transferring datagram from one node to physically adjacent node over a link. Attaches into host system"s bus (inside computer) Connects your device to the physical medium the wire . Nic encapsulates datagram in ll frame: src and dst ip and mac addresses. Group of computers that share a communication link. Communication does not go through a router. Once go through router, on the internet. Mac addresses provides node an addressable identity. Function: used locally to get frame from one interface to another physically-connected interface (same network) Hosts have an ip and mac addresses, plus maybe a name.
