What precisely is a link?
2
When reading about layer 2 the word "link" is frequently used but strangely I'm struggling to find a formal definition of it. What is the precise definition of a link? So in the image below, how many links are in this network and what makes that the case? Is it the physical cable between two devices, or can a link span multiple devices, or something else?
