1 Connecting to the Network Networking for Home and Small Businesses Chapter 3 1
2 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. 2
3 Networking and Its Benefits Define the term network and identify various types of networks 3
4 Networking and Its Benefits Describe the benefits of computer networking and list examples of small, medium and large networks 4
5 Networking and Its Benefits Define the components of an Information network 5
6 Networking and Its Benefits Describe the Roles of computers on a network Clients and servers 6
7 Networking and Its Benefits Build computer peer-to-peer network and verify 7
8 Network Topologies Differentiate between logical and physical topologies, and explain how networks are represented graphically 8
9 Communication Protocols Explain the concept of communication in terms of source, destination and channel 9
10 Communication Protocols Explain the need for rules and protocols in order for communication to occur 10
11 Communication Protocols Explain the concept of encoding in relation to human communication 11
12 Communication Protocols Explain the concept of message formatting and encapsulation 12
13 Communication Protocols Explain that messages have size restrictions depending on the channel used 13
14 Communication Protocols Explain the concept of timing and access methods in relation to human communication 14
15 Communication Protocols Explain standard message patterns in relation to human communication Unicast Multicast Broadcast 15
16 Communication Protocols Relate human communications concepts of messages, unit sizes, timing, encapsulation, encoding and standard message patterns to the term protocol. 16
17 Communication Across a Local Ethernet Network Explain that Devices on a local network must share common protocols to communicate (Communicating by the Rules) 17
18 Communication Across a Local Ethernet Network Identify the importance of standardization in computer communication protocols 18
19 Communication Across a Local Ethernet Network Physical addressing identifies Source, Destination and Channel on an Ethernet Network 19
20 Communication Across a Local Ethernet Network Describe some of the basic characteristics of Ethernet for communicating across the channel 20
21 Communication Across a Local Ethernet Network Describe the need for a hierarchical design in an Ethernet Network 21
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) 22
23 Access Layer Devices and Communication Methods Describe the Purpose of the Access Layer and how it is used within an Ethernet Network 23
24 Access Layer Devices and Communication Methods Describe the function of a Hub and how it operates within an Ethernet Network 24
25 Access Layer Devices and Communication Methods Describe the function of switches and how they are used in an Ethernet network 25
26 Access Layer Devices and Communication Methods Broadcast Domains and broadcasts using hubs and switches 26
27 Distribution Layer Devices and Communication Methods Describe the reasons for expanding your network with a distribution layer 27
28 Distribution Layer Devices and Communication Methods Describe the function of routers and how they are used in the network 28
29 Distribution Layer Devices and Communication Methods Explain the concept of the default gateway 29
30 Distribution Layer Devices and Communication Methods Describe how the router keeps tract of multiple networks using routing and ARP tables 30
31 Distribution Layer Devices and Communication Methods Define the term local area network (LAN) 31
32 Distribution Layer Devices and Communication Methods Differentiate between implications of adding hosts to My local network vs. adding to a remote network 32
33 Distribution Layer Devices and Communication Methods Learn to Use Packet Tracer 33
34 Plan, Implement and Verify a Local Network Plan and document the building of a small home or small business Ethernet network 34
35 Plan, Implement and Verify a Local Network Build a virtual model of their small home or small business network 35
36 Plan, Implement and Verify a Local Network Describe the features of multifunction devices and how they are used in the network 36
37 Plan, Implement and Verify a Local Network Connect and properly document the network installation 37
38 Plan, Implement and Verify a Local Network Perform simple workgroup tasks in order to share resources 38
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. 39
