  1. SMDS
  2. UCS
  3. ATM
  4. Short cells
  5. Answer pending.

Answer(s): E



Short cells:

  1. Are less likely to have errors.
  2. Have a destination address that is easy to read.
  3. Assure that delays between successive cells in the same message are minimal.
  4. Move more quickly than large cells.
  5. Answer pending.

Answer(s): E



A common source of delay in moving information rapidly through packet switches is:

  1. Waiting for the entire frame to enter the switch.
  2. The delay when an error is detected in a packet.
  3. Reading the destination address in the frame.
  4. All of the above
  5. Answer pending.

Answer(s): E
