Ethernet Delivers the Internet (continued)

The world-wide Internet is composed of millions of individual little networks, and every time an IP packet traverses any of them, it is encapsulated and then removed from framing such as that which we have illustrated here with Ethernet.

Ethernet Hubs and Ethernet Switches are not smart enough to do this. In order to look inside the Ethernet frame, find the internet protocol packet, interpret its structure, and find and handle the addressing, we use a smarter box known as a Router.

 

Routers also allow us to share a single Internet address obtained from our Internet service provider, with multiple computers inside our home or small office network. You can learn a lot more about routers elsewhere on AskMisterWizard.com.
