Switching vs Routing Overview
... A switch does not just pass electrical signals along, like a hub does; instead, it assembles the signals into a frame (layer two), and then decides what to do with the frame. A switch determines what to do with a frame by borrowing an algorithm from another common networking device: a transparent br ...
