10IPT: Network Protocols

posted Feb 19, 2013, 12:30 PM by Eddie Woo
We're going to finish looking at network topologies from yesterday's lesson, then we are going to jump into network protocols and look at one specific example of it. Here we go: 
  1. Justify the need for protocols on networks. 
  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. Define Carrier Signal Multiple Access with Collision Detection. 
  4. Describe the procedure that nodes execute when there is the simultaneous transmission of data from multiple nodes.
  5. 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)
