  1. OSI Data Link Layer • Presented By • Dr. WaleedAlseat • Mutah University

  2. 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.
