The Open Systems Interconnection Reference Model (OSI/RM) Application Layer serves which primary purpose? It provides the user interface to the system. The Open Systems Interconnection Reference Model (OSI/RM) Data Link Layer serves which primary purpose? It builds a flat network model with unroutable physical addresses.
Which of the following is the primary purpose of the Open Systems Interconnection Reference Model (OSI/RM) Transport Layer? It defines well known logical port addresses for communications between applications. The TCP/IP model Application Layer maps to which three Open Systems Interconnection reference model (OSI/RM) layers?
The Network Interface Layer adds the source and destination Internet protocol (IP) addresses, and forwards the packets to the Internetwork Layer. The Internetwork Layer builds frames and converts them to bits for transport across the physical network.
