Networking Basic
This lesson covers the very basics of networking. We’ll start with a little history that describes how the networking industry evolved. We’ll then move on to a section that describes how a LAN is built: essentially the necessary components (like NIC cards and cables). We then cover LAN topologies. And finally we’ll discuss the key networking devices: hubs, bridges, switches, and routers.
This module is an overview only. It will familiarize you with much of the vocabulary you hear with regards to networking. Some of these concepts are covered in more detail in later lessons
