    • Chapter 3 - Protocols and Models

    • Welcome to Protocols and Models!

      You know the basic components of a simple network, as well as initial configuration. But after you have configured and connected these components, how do you know they will work together? Protocols! Protocols are sets of agreed upon rules that have been created by standards organizations. But, because you cannot pick up a rule and look closely at it, how do you truly understand why there is such a rule and what it is supposed to do? Models! Models give you a way to visualize the rules and their place in your network. This module gives you an overview of network protocols and models. You are about to have a much deeper understanding of how networks actually work!

    • Chapter 6 - Data Link Layer


    • Welcome to Data Link Layer!

      Every network has physical components and media connecting the components. Different types of media need different information about the data in order to accept it and move it across the physical network. Think of it this way: A well-hit golf ball moves through the air fast and far. It can also move through water but not as fast or as far unless it is helped by a more forceful hit. This is because the golf ball is traveling through a different medium; water instead of air.

      Data must have help to move it across different media. The data link layer provides this help. As you might have guessed, this help differs based on a number of factors. This module gives you an overview of these factors, how they affect data, and the protocols designed to ensure successful delivery. Let’s get started!


    •  Topic Title  Topic Objective
       Purpose of the Data Link Layer  Describe the purpose and function of the data link layer in preparing communication for transmission on specific media.
       Topologies  Compare the characteristics of media access control methods on WAN and LAN topologies.

    • Chapter 7 - Ethernet Switching


    • Welcome to Ethernet Switching!

      If you are planning to become a network administrator or a network architect, you will definitely need to know about Ethernet and Ethernet switching. The two most prominent LAN technologies in use today are Ethernet and WLAN. Ethernet supports bandwidths of up to 100 Gbps, which explains its popularity. This module contains a lab using Wireshark in which you can look at Ethernet frames and another lab where you view network device MAC addresses. There are also some instructional videos to help you better understand Ethernet. By the time you have finished this module, you too could create a switched network that uses Ethernet!


    •  Topic Title  Topic Objective
       Ethernet Frame  Explain how the Ethernet sublayers are related to the frame fields.
       Ethernet MAC Address  Describe the Ethernet MAC address.
       The MAC Address Table  Explain how a switch builds its MAC address table and forwards frames.
       Switch Speeds and Forwarding Methods  Describe switch forwarding methods and port settings available on Layer 2 switch ports.

    • Chapter 8 - Network Layer


    • Welcome to Network Layer!

      By now you may have noticed that the modules in this course are progressing from the bottom up through the OSI model layers. At the network layer of the OSI model, we introduce you to communication protocols and routing protocols. Say you want to send an email to a friend who lives in another city, or even another country. This person is not on the same network as you. A simple switched network cannot get your message any further than the end of your own network. You need some help to keep this message moving along the path to your friend’s end device. To send an email (a video, or a file, etc.) to anyone who is not on your local network, you must have access to routers. To access routers, you must use network layer protocols. To help you visualize these processes, this module contains two Wireshark activities. Enjoy!


    •  Topic Title  Topic Objective
       Network Layer Characteristics  Explain how the network layer uses IP protocols for reliable communications.
       IPv4 Packet  Explain the role of the major header fields in the IPv4 packet.
       IPv6 Packet  Explain the role of the major header fields in the IPv6 packet.
       How a Host Routes  Explain how network devices use routing tables to direct packets to a destination network.
       Router Routing Tables  Explain the function of fields in the routing table of a router.

    • Chapter 9 - Address Resolution


    • Welcome to Address Resolution!

      Hosts and routers both create routing tables to ensure that they can send and receive data across networks. So how does this information get created in a routing table? As a network administrator, you could enter these MAC and IP addresses manually. But that would take a lot of time and the likelihood of making a few mistakes is great. Are you thinking that there must be some way that this could be done automatically, by the hosts and routers themselves? Of course, you are correct! And even though it is automatic, you must still understand how this works, because you may have to troubleshoot a problem, or worse, your network could be attacked by a threat actor. Are you ready to learn about address resolution? This module has several very good videos to help explain the concepts, as well as three Packet Tracer activities to cement your understanding. Why wait?


    •  Topic Title  Topic Objective
       MAC and IP  Compare the roles of the MAC address and the IP address.
       ARP  Describe the purpose of ARP.
       Neighbor Discovery  Describe the operation of IPv6 neighbor discovery.

    • Chapter 10 - Basic Router Configuration


    • Welcome to Basic Router Configuration!

      Have you ever run a relay? The first person runs the first leg of the race and hands off the baton to the next runner, who continues forward in the second leg of the race and hands off the baton to the third runner, and on it goes. Routing packets is very similar to a relay. But if the first runner does not know where to find the second runner, or drops the baton in the first leg, then that relay team will most certainly lose the race.

      Routing packets is very similar to a relay. As you know, routing tables are created and used by routers to forward packets from their local networks on to other networks. But a router cannot create a routing table or forward any packets until it has been configured. If you plan to become a network administrator you definitely must know how to do this. The good news? It is easy! This module has Syntax Checker activities so that you can practice your configuration commands and see the output. There are also some Packet Tracer activities to get you started. Let’s go!


    •  Topic Title  Topic Objective
       Configure Initial Router Settings  Configure initial settings on an IOS Cisco router.
       Configure Interfaces  Configure two active interfaces on a Cisco IOS router.
       Configure the Default Gateway  Configure devices to use the default gateway.

    • Chapter 11 - IPv4 Addressing


    • Welcome to IPv4 Addressing!

      Currently, there are still plenty of networks using IPv4 addressing, even as the organizations which use them are making the transition to IPv6. So it is still very important for network administrators to know everything they can about IPv4 addressing. This module covers the fundamental aspects of IPv4 addressing in detail. It includes how to segment a network into subnets and how to create a variable-length subnet mask (VLSM) as part of an overall IPv4 addressing scheme. Subnetting is like cutting a pie into smaller and smaller pieces. Subnetting may seem overwhelming at first, but we show you some tricks to help you along the way. This module includes several videos, activities to help you practice subnetting, Packet Tracers and a lab. Once you get the hang of it, you’ll be on your way to network administration!


    •  Topic Title  Topic Objective
       IPv4 Address Structure  Describe the structure of an IPv4 address including the network portion, the host portion, and the subnet mask.

    • Chapter 12 - IPv6 Addressing


    • Welcome to IPv6 Addressing!

      It is a great time to be (or become) a network administrator! Why? Because in many networks, you will find both IPv4 and IPv6 working together. After the hard work of learning to subnet an IPv4 network, you may find that subnetting an IPv6 network is much easier. You probably didn’t expect that, did you? A Packet Tracer at the end of this module will give you the opportunity to subnet an IPv6 network. Go ahead, jump in!


    •  Topic Title  Topic Objective

    • Chapter 14 - Transport Layer


    • Welcome to Transport Layer!

      The transport layer is where, as the name implies, data is transported from one host to another. This is where your network really gets moving! The transport layer uses two protocols: TCP and UDP. Think of TCP as getting a registered letter in the mail. You have to sign for it before the mail carrier will let you have it. This slows down the process a bit, but the sender knows for certain that you received the letter and when you received it. UDP is more like a regular, stamped letter. It arrives in your mailbox and, if it does, it is probably intended for you, but it might actually be for someone else who does not live there. Also, it may not arrive in your mailbox at all. The sender cannot be sure you received it. Nevertheless, there are times when UDP, like a stamped letter, is the protocol that is needed. This topic dives into how TCP and UDP work in the transport layer. Later in this module there are several videos to help you understand these processes.


    •  Topic Title  Topic Objective
       Transportation of Data  Explain the purpose of the transport layer in managing the transportation of data in end-to-end communication.
       TCP Overview  Explain characteristics of TCP.
