  1. 4. The arrangement of cabling and how cables connect one device to another in a network are considered:
  2. 9. what transmission method sends digital signals in which each bit of data is represented by a pulse of electricity or light.
  3. 10. is like a bus, in that devices are daisy-chained one to another, but instead of terminating each end, the cabling is brought around from the last device back to the first device to form a ring.
  4. 12. Ethernet can also detect whether a frame has been damaged in transit. The errorchecking code in an Ethernet frame's trailer is called a ()？
  5. 13. what systems use analog techniques to encode binary 1s and 0s across a continuous range of values.
  6. 16. the term used when electricity bounces off the end of a cable and back in the other direction is called:(__or reflection)
  7. 19. the extent to which signals in an Ethernet bus topology network are propagated is called()?
  8. 20. is a direct link between two devices. It's most often used in WANs, in which a device on a business's network has a dedicated link to a telecommunication provider.

  1. 1. waht is the most widely used in networks containing more than just a few computers.
  2. 2. The path data travels between computers on a network is considered:
  3. 3. the media access method that Ethernet uses in half-duplex mode is()?
  4. 5. Point-topoint topologies are also used with wireless networks in what is called a ().
  5. 6. what connects eachdevice to every other device in a network?
  6. 7. what is by far the simplest topology and one time was the most common method for connecting computers.
  7. 8. the signals continue traveling along the cable and through any connecting devices until they weaken enough that they can't be detected or until they encounter a device that absorbs them. this traveling across the medium is called?
  8. 11. what uses two strands of fiber-optic cable, is often the best choice of netwrok technology?
  9. 14. what is the most common Ethernet variety?
  10. 15. what uses a central devices such as a hub or switch, to interconnect computers in a LAN
  11. 17. waht occurs if two or more devices on the smae medium transmit simultaneously.
  12. 18. An electrical component called a "resistor" that absorbs the signal instead of allowing it to bounce back up the wire.
