Networking Concepts and IP Addresses

This video is the first lesson in a Networking Fundamentals course, focusing on how data flows through the internet. It covers the concepts of hosts, IP addresses, and networks. Hosts are devices that send or receive traffic, including computers, cloud resources, and IoT devices. IP addresses serve as the identity of each host, essential for internet communication. Networks are logical groupings of hosts that facilitate data transfer. The lesson emphasizes understanding these concepts and their hierarchical nature, setting the stage for further exploration of network devices.
