Have you ever wondered how networks work? How two computers communicate? How the Internet works? This course explains these concepts, starting with the basic building blocks of networks, and how Ethernet Local Area Networks (LANs) operate. We discuss IP addressing and subnetting, and how data gets routed from one LAN to another using various Wide Area Networking (WAN) technologies.
This course is appropriate for anyone new to networking and looking to learn the basics, as well as anyone wanting to brush up on a particular topic. This course includes a comprehensive glossary of terms that explain the lingo as it relates to the topic being covered. It also includes numerous interactive exercises to help teach and reinforce the information as well as test your knowledge and understanding of the topic. A Final Challenge helps users assess their understanding of the concepts covered.
