In this guide we will focus on general, big-picture truths about telecommunication. Networks are basically just a bunch of links and nodes.
Links connect nodes, and nodes connect links.
The way in which a network's nodes and links are arranged is referred to as its topology. The simplest topology is two nodes connected by one link. As nodes and links are added the possible topologies increase. Each segment of the telecommunication industry has different terms for the nodes and links in their networks. This level of understanding is critical for working in a world of transvergence.
