Course Details

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.
