Objectives Explain the concept of networking and the benefits of

networks.

Explain the concept of communication protocols.

Explain how communication occurs across a local Ethernet network.

Describe Access layer devices and communication methods on a local Ethernet network.

Describe Distribution layer devices and communication methods across networks.

Plan, implement, and verify a local network.


Networking and Its Benefits Define the term network and identify various types of

networks


Networking and Its Benefits Describe the benefits of computer networking and list

examples of small, medium and large networks


Networking and Its Benefits Define the components of an Information network


Networking and Its Benefits Describe the Roles of computers on a network

Clients and servers


Networking and Its Benefits Build computer peer-to-peer network and verify


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

communicationUnicast

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.
