tailieunhanh - Lecture Network Fundamentals – Chapter 7: OSI Data Link Layer

In this chapter, you learned 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,. Inviting you to refer. | OSI Data Link Layer Network Fundamentals – Chapter 7 Objectives 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. Data Link Layer – Accessing the Media Describe the service the Data Link Layer provides as it prepares communication for transmission on specific media Data Link Layer – Accessing the Media Describe why Data Link layer protocols are required to control media access Data Link Layer – Accessing . | OSI Data Link Layer Network Fundamentals – Chapter 7 Objectives Explain the role of Data Link layer protocols in data transmission.
