The Open Systems Interconnection reference model (OSI/RM) Physical Layer serves which primary purpose?It transmits data in the form of bits across the physical medium. 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. The Open Systems Interconnection Reference Model (OSI/RM) Application Layer serves which primary purpose?It provides the user interface to the system. Which is the primary purpose of the Open Systems Interconnection reference model (OSI/RM) Session Layer?It establishes, manages, and terminates dialogs between Presentation Layer entities. 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 Open Systems Interconnection Reference Model (OSI/RM) Network Layer serves which primary purpose?It uses Layer 3 (Network Layer) addresses to create multiple routed networks. Which is the primary purpose of the Open Systems Interconnection reference model (OSI/RM) Presentation Layer?It defines the format in which Application Layer information is sent across the network. Which of the following best describes an email message's communication flow through the TCP/IP model layers?The Transport Layer breaks the data stream into pieces, which it passes to the Internetwork Layer. The Internetwork Layer adds the source and destination Internet protocol (IP) addresses and forwards the packets to the Network Interface Layer. The Network Interface Layer builds frames, and converts them to bits for transport across the physical network.
