CCNA Exploration 1(V 4.0) : Chapter 7,8,9,10 objectives

Chapter 7:  OSI Data Link Layer

• 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

Chapter 8: OSI Physical Layer

• Explain the role of Physical layer protocols and services in supporting communication across data networks.
• Describe the role of signals used to represent bits as a frame as the frame is transported across the local media.
• Describe the purpose of Physical layer signaling and encoding as they are used in networks.
• Identify the basic characteristics of copper, fiber and wireless network media.
• Describe common uses of copper, fiber and wireless network media.
