|In it's simplest definition, a bridge is a device that connects two networks. Whether or not you wish to have access between the two networks is moot. It can be either way. In fact, most often a bridge is used to join networks.|
What I don't understand is why the bridge is nessessary ie, why can't you just connect the two switches with a cross over cable then all computer would be able to talk to each other right?
First off, I didn't watch the video. I don't want to download and watch the whole thing.
There may be a specific reason for not connecting the two switches directly as you've said. Distance is one. If the two switches are more than 100 m apart. A bridge is a quick, easy, inexpensive way to join the two network segments.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
