The media access control methods described by the Data Link layer protocols define the processes by which network devices can access the network media and transmit frames in diverse network environments. | Module 7- Data Link Layer -------------------mwkhoa neïworki no academy CCNA Exploration CISCO 1 Overview Học viện mạng Bách khoa - Website 2 Overview Upon completion of this chapter you will be able to Explain the role of Data Link layer protocols in data transmission. Describe how the Data Link layer prepares data for transmission on network media. Describe the different types of media access control methods. Identify several common logical network topologies and describe how the logical topology determines the media access control method for that network. Explain the purpose of encapsulating packets into frames to facilitate media access. Describe the Layer 2 frame structure and identify generic fields. Explain the role of key frame header and trailer fields including addressing QoS type of protocol and Frame Check Sequence. Học viện mạng Bách khoa - Website
