Network Topologies Differentiate between logical and physical topologies, and explain how networks are represented graphically

Communication Protocols Explain the concept of communication in terms of source, destination and channel

Communication Protocols Explain the need for rules and protocols in order for communication to occur

Communication Protocols Explain the concept of encoding in relation to human communication

Communication Protocols Explain the concept of message formatting and encapsulation

Communication Protocols Explain that messages have size restrictions depending on the channel used

Communication Protocols Explain the concept of timing and access methods in relation to human communication

Communication Protocols Explain standard message patterns in relation to human communication Unicast Multicast Broadcast

Communication Protocols Relate human communications concepts of messages, unit sizes, timing, encapsulation, encoding and standard message patterns to the term “protocol” .

Communication Across a Local Ethernet Network Explain that Devices on a local network must share common protocols to communicate (Communicating by the Rules)

Communication Across a Local Ethernet Network Identify the importance of standardization in computer communication protocols

Communication Across a Local Ethernet Network Physical addressing identifies Source, Destination and Channel on an Ethernet Network

Communication Across a Local Ethernet Network Describe some of the basic characteristics of Ethernet for communicating across the channel

Communication Across a Local Ethernet Network Describe the need for a hierarchical design in an Ethernet Network

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)

Access Layer Devices and Communication Methods Describe the Purpose of the Access Layer and how it is used within an Ethernet Network

Access Layer Devices and Communication Methods Describe the function of a Hub and how it operates within an Ethernet Network

Access Layer Devices and Communication Methods Describe the function of switches and how they are used in an Ethernet network

Access Layer Devices and Communication Methods Broadcast Domains and broadcasts using hubs and switches

Distribution Layer Devices and Communication Methods Describe the reasons for expanding your network with a distribution layer

Distribution Layer Devices and Communication Methods Describe the function of routers and how they are used in the network

Distribution Layer Devices and Communication Methods Explain the concept of the default gateway

Distribution Layer Devices and Communication Methods Describe how the router keeps tract of multiple networks using routing and ARP tables

Distribution Layer Devices and Communication Methods Define the term “local area network (LAN)”

Distribution Layer Devices and Communication Methods Differentiate between implications of adding hosts to “My local network” vs. adding to a “remote network”

Distribution Layer Devices and Communication Methods Learn to Use Packet Tracer

Plan, Implement and Verify a Local Network Plan and document the building of a small home or small business Ethernet network

Plan, Implement and Verify a Local Network Build a virtual model of their small home or small business network

Plan, Implement and Verify a Local Network Describe the features of multifunction devices and how they are used in the network

Plan, Implement and Verify a Local Network Connect and properly document the network installation

Plan, Implement and Verify a Local Network Perform simple workgroup tasks in order to share resources

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.
