  • 9. Communication Protocols
    • Explain the concept of communication in terms of source, destination and channel
  • 10. Communication Protocols
    • Explain the need for rules and protocols in order for communication to occur
  • 11. Communication Protocols
    • Explain the concept of encoding in relation to human communication
  • 12. Communication Protocols
    • Explain the concept of message formatting and encapsulation
  • 13. Communication Protocols
    • Explain that messages have size restrictions depending on the channel used
  • 14. Communication Protocols
    • Explain the concept of timing and access methods in relation to human communication
  • 15. Communication Protocols
    • Explain standard message patterns in relation to human communication
      • Unicast
      • Multicast

  • 16. Communication Protocols
    • Relate human communications concepts of messages, unit sizes, timing, encapsulation, encoding and standard message patterns to the term “protocol” .
  • 17. Communication Across a Local Ethernet Network
    • Explain that Devices on a local network must share common protocols to communicate (Communicating by the Rules)
  • 18. Communication Across a Local Ethernet Network
    • Identify the importance of standardization in computer communication protocols
  • 19. Communication Across a Local Ethernet Network
    • Physical addressing identifies Source, Destination and Channel on an Ethernet Network
  • 20. Communication Across a Local Ethernet Network
    • Describe some of the basic characteristics of Ethernet for communicating across the channel
  • 21. Communication Across a Local Ethernet Network
    • Describe the need for a hierarchical design in an Ethernet Network
  • 22. Communication Across a Local Ethernet Network
    • Explain the purpose of a logical network address as the location of a host on a Network (source and destination)
  • 23. Access Layer Devices and Communication Methods
    • Describe the Purpose of the Access Layer and how it is used within an Ethernet Network
  • 24. Access Layer Devices and Communication Methods
    • Describe the function of a Hub and how it operates within an Ethernet Network
  • 25. Access Layer Devices and Communication Methods
    • Describe the function of switches and how they are used in an Ethernet network

    • Define the term “local area network (LAN)”
  • 32. Distribution Layer Devices and Communication Methods
    • Differentiate between implications of adding hosts to “My local network” vs. adding to a “remote network”
  • 33. Distribution Layer Devices and Communication Methods
    • Learn to Use Packet Tracer
  • 34. Plan, Implement and Verify a Local Network
    • Plan and document the building of a small home or small business Ethernet network

    • Build a virtual model of their small home or small business network
  • 36. Plan, Implement and Verify a Local Network
    • Describe the features of multifunction devices and how they are used in the network
  • 37. Plan, Implement and Verify a Local Network
    • Connect and properly document the network installation
  • 38. Plan, Implement and Verify a Local Network
    • Perform simple workgroup tasks in order to share resources
  • 39. Summary
    • Information networks carry data using hosts as clients, servers, or both.
    • All computer communication involves a source, destination, and channel.
    • Rules called protocols govern computer communications.
    • Larger networks are divided into smaller, more manageable ones using a layered hierarchical design.
    • Each network host needs both a physical MAC address and a logical IP address.
    • Good network design requires a network plan.
