More technology self-tutoring: the tutor explains his understanding of switch, a term he’s found tricky to define.
Switches can be used in a variety of ways, so a simple conception only explains one application. However, I find this idea helpful:
Imagine a self-contained local network of computers physically connected. A given member can send a message to a specific other, or to all others at once. Then, the simplest central connection among these computers is a switch.
A switch is different from a hub (once again, my post from yesterday) in that the switch can forward a message to a specific intended recipient, whereas the hub just forwards it to everyone.
