  3. What’s the Speed of Fast Ethernet? • A. 10 Mbps • B. 4/16 Mbps • C. 100 Mbps • D. 1000 Mbps • E. None of the Above

  4. A Leased Line that has speeds of 1.544 Mbps? • A. 56k • B. T1 • C. T3 • D. OC3 • E. All of the Above

  5. A Network Architecture based on token passing around a dual fiber ring is? • A. ATM • B. CDDI • C. Token Ring • D. FDDI • E. Fast Ethernet

  6. Fill in the Blanks

  7. The 3 firms involved with the original development of the Ethernet standard were _______________, __________________ and __________________. • Dec, Xerox Intel

  8. A typical ethernet address is made up of ________ hex digits. An example would look like ______________. A typical ip address is written down with ________ distinct parts (sections), where each part ranges from _____ to _______. An example would look like _________. • 12, 1A:BC:F4:44:6C:A1, 4 , 0, 255, 165.230.99.70

  9. Some of the Rules for Ethernet: 10Base5: _______ maximum segment length _______ maximum number of segments 10BaseT: _______ maximum distance from hub to a given system • 500m, 5, 100m

  10. Acronym Expansions

  11. MAU • Multistation Access Unit • TCP/IP • Transmission Control Protocol/Internet Protocol • DSL • Digital Subscriber Line

  12. Simple Definitions

  13. Attenuation • The loss of signal strength over a distance. Occurs with electrical signals over copper, light over fiber, voice over the air. • Crosstalk • Interference created by surrounding wires, minimized by twisted pair wiring • UPS • Uninterruptable Power Supply, provides protection against voltage spikes/dips, as well as continued power in case of power outage

  14. Questions and Answers

  15. What are some of the positive aspects of a Lan? Why Lans?

  16. In telecommunications, we talked about “encoding” the data. What is meant by that? Explain some methods? Why is it needed? Is it useful for lans/wans also?

  17. Compare and Contrast the 3 main network topologies.

  18. Clearly Explain how CSMA/CD works.

  19. Draw a ethernet packet and show all fields and their sizes. Also draw a asynchronous data packet, again showing all fields and sizes.

  20. The End!
