In this Packet Tracer activity, you will complete the following objectives: Packet Tracer – Create a LAN (14.3.4)In this Packet Tracer activity, you will complete the following objectives: Reflection Questions (14.4.2) On my home network (LAN), I do not usually have enough network traffic to experience congestion, although it can happen when all my children…

End devices, both clients and servers are connected to LANs. The LAN is how users access their network and reach other networks.Local Area Networks (14.3.1)The term local area network (LAN) refers to a local network, or a group of interconnected local networks that are under the same administrative control, as shown in Figure 14-4. In…

A router is a Layer 3 intermediary device that performs the packet forwarding or routing. Routers have routing tables that contain the information the router needs to forward the packet. Video – Router Packet Forwarding (14.2.1) Refer to the online course to view this video. Video – Messages Within and Between Networks – Part 1…

Objectives Upon completion of this chapter, you will be able to answer the following questions: • What is the need for routing? • How do routers use tables? • How do you build a fully connected network? Key Terms This chapter uses the following key terms. You can find the definitions in the Glossary. Default…

• MAC and IP—Sometimes a host must send a message, but it only knows the IP address of the destination device. The host needs to know the MAC address of that device. The MAC address can be discovered using address resolution. There are two primary addresses assigned to a device on an Ethernet LAN: •…

When a host receives a message addressed to the broadcast address, it accepts and processes the message as though the message was addressed directly to it. When a host sends a broadcast message, switches forward the message to every connected host within the same local network. For this reason, a local area network, a network…

When the destination IP address (IPv4 or IPv6) is on a remote network, the destination MAC address will be the address of the host default gateway (i.e., the router interface). In Figure 13-2, PC1 wants to send a packet to PC2. PC2 is located on remote network. Because the destination IPv4 address is not on…

Objectives Upon completion of this chapter, you will be able to answer the following questions: • What is the difference between the roles of the MAC address and the IP address? • Why it is important to contain broadcasts within a network? Key Terms This chapter uses the following key terms. You can find the…

The following is a summary of each topic in the chapter and some questions for your reflection. What Did I Learn in this Module? (12.3.1) • Network Boundaries— Every host on a network must use the router as a gateway to other networks. Therefore, each host must know the IPv4 address of the router interface…

The wireless router acts as a DHCP server for all local hosts attached to it, either by Ethernet cable or wirelessly. These local hosts are referred to as being located on an internal, or inside, network. Most DHCP servers are configured to assign private addresses to the hosts on the internal network, rather than internet…
