CCNA Sem 1 - Module 7 Index

Module 7: Ethernet Technologies
Overview
Convey to the students how Ethernet technology has increased in speed from 10 Mbps to 10,000 Mbps in less than a decade. Emphasize that the frame structure on all Ethernet speeds have the same frame characteristics. This leads to excellent interoperability on 10/100/1000 Ethernet interfaces.
Note: Most Ethernet copper connections are switched full duplex and the fastest copper-based Ethernet is 1000BASE-T. Ethernet at speeds of 10-Gigabit and faster are exclusively optical fiber-based technologies. There are basic considerations that help drive the architectural rules of Ethernet. Examples are the 100-meter rule for copper and the tradeoff that exists between distance and bandwidth
in fiber.

Module 7 Caution
The introduction of the facts and terminology in this module can easily overwhelm the students. The encoding schemes presented in the curriculum detail important characteristics on the different Ethernet varieties. The complexity surpasses what is needed for certification. Therefore, the material presented is useful as background information. The Protocol and Network Analysis software are powerful but complex tools. To use such powerful tools without confusing students in an introductory course requires a significant amount of preparation by the instructor.

Students completing this module should be able to perform the following tasks:
• Compare and contrast 10BASE5, 10BASE2, and 10BASE-T Ethernet technology
• Define Manchester encoding
• List the factors affecting Ethernet timing limits
• List 10BASE-T wiring parameters
• Describe the key characteristics and varieties of 100-Mbps Ethernet
• Describe the evolution of Ethernet
• Explain the MAC methods, frame formats, and transmission process of Gigabit Ethernet
• Describe the uses of specific media and encoding with Gigabit Ethernet
• Identify the pinouts and wiring typical to the various implementations of Gigabit Ethernet
• Compare and contrast Gigabit and 10-Gigabit Ethernet
• Describe the basic architectural considerations of Gigabit and 10-Gigabit Ethernet

Reading to be Done:

READ MODULE 7 ON LINE -- read it twice, even three times to retain the information

There are interactive media options available at the end of some of the pages. It would be helpful TO YOU if you attempted these. The quizzes are also a good option. They give you an idea of what to expect on the test.
