1.3 Define basic LAN terminology.
1.4 Explain how LAN operating systems work.
Read the course description and objectives.
Read the instructor’s biography and post your own.
Read Appendix A.
Read Ch. 2, “Network Hardware Essentials,” of Guide to Networking Essentials.
Read Ch. 3, “Network Topologies and Technologies,” of Guide to Networking Essentials.
Read Ch. 6, “Network Reference Models and Standards,” of Guide to Networking Essentials.

DQ1- Day 2
DQ2- Day 4
LAN Operating Systems Scenarios
Read the three scenarios in Appendix B.
Answer the questions following each scenario for a total of 200 to 300 words. Day 5
Week Two, Mar 10, 2014: The OSI Model and Topologies
2.1 Define key terms related to the OSI model.
2.2 Describe the functions of hardware connectivity devices and tools. 2.3 Illustrate different LAN topologies.
OSI Model Key Terms Table
Use the table in Appendix C to define the key terms related to the OSI model. Describe the functions of any hardware connectivity devices and tools listed. Post Appendix C as an attachment.
Read Case Projects 3-1, 3-2, & 3-3 of the Guide to Networking Essentials.
Determine what type of physical and logical topology will be used for each scenario. Substantively explain the reasoning for your answer.
Create a visual representation of each chosen topology by copying and pasting the shapes provided in Appendix D—such as a bus, ring, star, or mesh—into a Microsoft® Word document. Note that you will need to use the Draw feature in Microsoft® Word to create lines between the shapes, and you may have to use some shapes more than once. Refer to the Figures 3-1 through 3-4 of Guide to Networking Essentials for examples.
Post your assignment as an attachment.
Week Three, Mar 17, 2014: Technology Types
3.1 Differentiate between types of Internet connectivity.
3.2 Compare and contrast fat client and thin client concepts. 3.3 Plan an Ethernet LAN.
Read the “Fiber Distributed...
