In today's lesson, we've looked at one method of controlling data flow on a network: Carrier Signal Multiple Access with Collision Detection. Complete the following tasks:
  1. Define the parts of this protocol's name.
  2. Explain why a protocol for handling collisions is needed for a network using a bus topology, but not for a network using a ring topology.
  3. Describe the procedure that nodes execute when there is the simultaneous transmission of data from multiple nodes.
  4. CSMA/CD is not the only protocol for handling collisions. Use the internet to research the following protocols and identify their distinguishing characteristics:
    • CSMA/CA
    • MACAW (wireless)
    • PCF (wireless)
For reference: [communications system framework]
