*Media Access Control (MAC) Sublayer- Translates generic network request into device specific terms. What are the two sublayers?ДЄnswer: *MAC *LLC Explanation:The Data link layer is split into the following sublayers: *Logical Link control (LLC) Sublayer- Provides the operating system link to the device driver. The Data Link layer of the OSI model is comprised of two sublayers.

Which of the following functions are performed at the Physical layer of the OSI model?ДЄnswer: *Movement of data across network cables Explanation: The Physical layer is concerned with how to transmit data and how to connect network hosts. Data translation is performed at the Presentation layer. Conversation identification is accomplished at the Session layer through connection or transaction ID numbers. Applications actually run above the OSI Application layer. In the OSI model, which of the following functions are performed at the Application layer? (Select all that apply.)ДЄnswer: *Integration of network functionality into the host operation system *Enabling communication between network clients and services Explanation: The Application layer enables network services, and integrates network functionality into the host operating system. Transmitting frames happens at the Physical layer. Flow control and error detection the provided at both the Transport layer and the Data Link layer. The Session Layer maintains separate client connections through sessions IDs, and maintains those sessions. The application layer provides network services. In the OSI model, which of the following functions are performed at the Presentation layer? What are the two?ДЄnswer: * Encrypt and compress data *Specify data format (such as file formats) Explanation: The presentation layer encrypts data, changes and converts character sets, and compresses data. In the OSI model, what is the primary function of the Network layer?ДЄnswer: * Routes messages between network Explanation: The network layer is responsible for routing messages between networks. The other functions listed here are performed by the Physical layer. Explanation: The Data Link layer controls identifying devices on a network as well as how messages travel through the network (the logical topology). Which two of the following are included as part of Data Link layer specifications?ДЄnswer: * Controlling how messages are propagated through the network. The open system interconnection model is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology.
