Most networks use intermediate systems to reduce cabling costs and complexity. In this topic, you will summarize the functions of hub, bridge, and switch appliances working at the Physical and Data Link layers.
A host on a network sends a frame to the hub. Which other devices on the network will see this frame?
A host on a network sends a frame to a switch. Which other devices on the network will see this frame?
What are the similarities and differences between a bridge and a switch?
What are the advantages of using switches instead of hubs?
What is the difference between a managed and an unmanaged switch?

As a network technician, you will frequently be involved with installing, configuring, and troubleshooting Ethernet network interfaces and transceivers. A network interface is the means by which a node is connected to the media and exchanges data with other network hosts. This involves both a physical connection to the network media and the use of a data link protocol such as Ethernet to perform addressing and framing. Understanding the properties of these components is essential for selecting appropriate products and configuring them correctly.

Begin reading the 1.3.1 – Copper Cables.pptx presentation on the Google Classroom. This lesson will introduce you to different types of copper cables and their standard characteristics.
Next, visit the How to Make a Network Cable: link at https://www.wikihow.com/Make-a-Network-Cable for instructions on how to build a Cat5e cable to the EIA/TIA 568A or 568B spec. Read through the instructions completely before proceeding. Pay particular notice to the difference between a “passthrough” cable and a “crossover” cable.
Visit the rolling cart to pick up your tools and materials. You will need a arm’s length of Cat5e cable, two RJ-45 cable ends, and a crimper tool.
Follow the instructions to build your passthrough patch cable.
Once you have your passthrough cable built, test it using the provided cable tester. If your cable test is successful, you may proceed to build a “crossover” cable for extra credit.
Use clear tape and a marker to label your cables with your name and what type of cable it is (passthrough or crossover), and place it in the wire basket on the front table in the room.
Once they are graded, you are free to take your Cat5e cable home for your own use. Cables left behind will be deployed within the department.

Assignment:
Begin reading the 1.1.2 – Encapsulation and Decapsulation.pptx presentation. This lesson will introduce you to what encapsulation and decapsulation is, and how it works with the OSI model we studied yesterday.
Next, complete the 1.1.2 – Lab – Encapsulation and Decapsulation with Wireshark.pptx Lab posted in the Google Classroom. We will review the concepts presented in the lab to help explain how packets are formed, transmitted, received and decoded.
To complete this lab, ping a website of your choice while Wireshark is capturing packets, and filter the IP address that you pinged. Post a screenshot of the filtered search to today’s Assignment post in the Google Classroom.
Please do your best to complete this activity by the end of the day on Wednesday, September 18th.
