  11. Topology & Signals 400 • The process of adding headers to data as it moves through the layers of the OSI model is • Demultiplexing • Encapsulation • Encoding • Encryption • Segmentation A: What is encapsulation?

  12. Topology & Signals 500 • Why do hosts waiting to transmit data react to a collision on a DSMA/CD network? • Computers involved in the collision have priority to retransmit data • Computers listen to the network wire for a change to send data at the end of the backoff period • Computers that were not involved in the collision will send an all-clear signal through the network • Computers involved in the collision send a jam signal through the network to clear the collision A: What is Option 2?
