Across
  1. 3. A multiplexor that un-multiplexes the data stream and delivers the individual streams to the appropriate devices
  2. 4. A number indicating a protocol's reliability
  3. 6. A multiplexing technique where binary 1s and 0s are replaced with larger, unique binary sequences to allow multiple user to share a common set of frequencies
  4. 8. A set of unused frequencies between 2 channels on a frequency division multiplexed system
  5. 13. A adaptive routing technique in which routing tables react to network fluctuations when calculating the best paths between networks
  6. 15. A second Generation mobile telephone technology that is based on a form of time division multiplexing
  7. 16. A transitional cellular network technology between 3G and 4G that takes advantage of some improved 4G technologies to exceed 3G speeds
  8. 19. A type of routing protocol that enables routers to share performance and status information about their connected links with routers throughout the network
  9. 23. The device that combines multiple input signals for transmission over a single medium and then demultiplexes the composite signal back into multiple signals
  10. 24. An expensive form of wavelength division multiplexing that involves the transfer of a large number of data streams over a single optical fiber using multiple lasers emitting light of different wavelengths
  11. 26. Assigning non-overlapping frequency ranges to different signals or to each user of a medium
  12. 28. The use of one or more fixed routes manually added to the routing table, often when the network is installed
  13. 30. 4th generation mobile phone service characterized by an all-IP network for both data and voice transmission
  14. 31. A path vector routing protocol that is the only routing protocol used on the open Internet
  15. 32. A compression technique that offers lossless compression by creating a dictionary of character strings and associated codes
  16. 33. A compression technique in which data is compressed and then decompressed but doesn't return the original data
  17. 36. A compression technique in which data is compressed and the decompressed such that the original data is returned
  18. 38. Early cellular phone networks
Down
  1. 1. The multiplexing of multiple data streams onto a single fiber-optic cable through the use of lasers emitting lights of varying wavelength
  2. 2. The simplest type of routing protocols; used to determine the best route for data based on the distance to a destination
  3. 5. A form of multiplexing that relies on multiple antennae transmitting and receiving in different locations so that signals are separated by some distance in space
  4. 7. A multiplexing technique that gives each incoming source a turn to transmit, proceeding through the sources in round-robin fashion
  5. 9. A technique commonly used to compress images
  6. 10. A path or connection typically supporting one user
  7. 11. The process of a network reconfiguring itself if a network failure is detected
  8. 12. A compression technique in which a commonly occurring symbol in a data set is replaced with a simpler character and a count of how many times that symbol occurs
  9. 14. A database stored in a router's memory that maintains information about the location of hosts and networks and the best paths for forwarding messages between them
  10. 17. A link state routing protocol that uses a best-path algorithm
  11. 18. A routing protocols that exhibits characteristics of both distance vector and link state routing protocols
  12. 20. distance vector protocols that use hop count as their routing metric and only allow up to 15 hops
  13. 21. Modern multiplexing technology technology that combines FDM and TDM techniques and takes advantage of mathematical manipulation of wavelengths to compress multiple signals within a smaller bandwidth
  14. 22. The application of multiplexing in the support of many users at one time
  15. 25. Techniques used to decrease the demand on limited WAN resources and increase the effective speed of data transmissions over WAN connections
  16. 27. 3rd generation mobile phone service released in the early 2000s that supported up to 384 Kbps
  17. 28. A form of time division multiplexing in which the multiplexor creates a data packet of only those devices that have something to transmit
  18. 29. A multiplexing technique in which the sharing of a signal is accomplished by dividing the available transmissions on a medium among the medium's users
  19. 34. A compression/encryption technique that allows a high quality audio sample to be reduced to a much smaller sized file
  20. 35. A link state routing protocol that improves on some of the limitations of RIP and con coexist with RIP on a network
  21. 37. An advanced distance vector routing protocol developed by Cisco that combines some of the features of a link state routing protocols and so is sometimes referred to as a hybrid protocol
