1.The lecture covers several standards. Which ones are most common? Which ones are more or less obsolete? What can you find out about the future of transmission and media types? What is happening with 10 Gbps? What about 100 Gbps?
2 Let's figure out what kind of networking equipment an organization would need to buy. You can make assumptions on size and budget. What do we need to purchase? Why do we need to purchase it? That is, what will it do for us? How do we hook them together? That is, how do we cable them (or not cable them) together? Why is there such a big difference in price with the brands? How do network topologies figure into our selections and designs?
3Before the week gets away from us, let's touch on one of the key concepts of TCO 4, which states, "Given a requirement for a network with a specified maximum response time to client requests, select an appropriate logical and physical network topology and access protocol, and identify the factors involved in the selection. Ease of maintenance should also be considered." Please describe the difference between logical and physical topologies.
4.Hubs were used frequently in the 1980s. Why don't we incorporate hubs into our networks as much anymore?
Can you name some additional network devices that have become obsolete? Why is that the case?
5.Fiber is currently a popular transmission media, with a major drawback being the cost of repairing it if it gets damaged. Discuss some additional pros and cons on different transmission media currently in use. What do you think will be the most common transmission media in 10 years? In 20 years?
6. TCO 3 states, "Given a requirement for a network, identify alternative network transmission media options, recommend the appropriate media, and justify the
recommendation."
Pick one of the following key concepts of TCO 3 to discuss in detail:
describe the difference between bounded and unbounded media, and provide exs of each that are commonly found in homes, schools, or area businesses.
describe signal degradation, its causes, and ways to minimize it.
Provide exs of sources of interference in the environment.
