Compare and contrast Internet backbone networks with local area networks
The Internet backbone networks are giant networks with extremely large and powerful computers and very large bandwidth network connections. The backbone interconnections are built with large capacity, multi-channel fiberglass or very large cables. The computers are large capacity with sophisticated software to look up IP address (DNS – data name servers) and route the traffic. Most are owned by governments or large telecommunications companies such as AT&T or Verizon.
Local Area Networks (LANS) are typically limited to a single home or office or building. They don't require routing computers, maybe just a local router or switch. The traffic is all local. Local servers may reside on a LAN, but in that case (local only), they are only visible on the LAN itself. LANs, however, can a do connect to the Internet and then the computers, either servers or personal computers, do have access to the Internet.
