Course Description
In this course, you will learn about the different network layers—L1, L2, and L3—and what sorts of network connectivity problems each layer can experience. From there we’ll cover MAC addresses and how they relate to IP addresses via address resolution protocols. You will also learn about how network interface cards function and their role in determining network speed.
We’ll provide an overview of hardware routing and explain how it connects to various sites from your computer. You’ll also learn about the device drivers needed to install network interface cards and the differences between generic and vendor-specific driver performance. By the end of this course, you’ll be able to tell when the hardware itself is what’s causing connectivity issues—and what to do about it.
What You'll Learn
- Identify the connection between a MAC address and an IP address through address resolution protocols
- Understand the purpose and function of network interface cards and their role in determining network speed
- Distinguish the network layers L1, L2, and L3 and the connectivity problems each can experience
- Explain how hardware routing connects your computer to various sites
- Compare generic versus vendor-specific device driver performance when installing network interface cards
- Recognize when network hardware itself is the cause of connectivity issues and what to do about it
Key Takeaways
- Network connectivity problems can occur at different network layers (L1, L2, and L3), each with its own types of issues.
- MAC addresses relate to IP addresses through address resolution protocols.
- Network interface cards function in a way that helps determine network speed.
- Hardware routing connects a computer to various sites.
- The device drivers used to install network interface cards differ in performance between generic and vendor-specific drivers.
