2. What is the Internet?

3. The Internet It is a collection of thousands of individual networks and organizations, each of which is run and paid for on its own. networks Each network cooperates with other networks to direct Internet traffic so that information can pass among them. Together, these networks and organizations make up the wired world of the Internet.

12. TCP/IP= The Transmission Control Protocol/Internet Protocol is the protocol suite that drives the Internet. – Handles network communications between network nodes (computer, or nodes, connected to the net). TCP- – the language computers use when communicating over the Internet. – the movement of data between applications IP- – handles the movement of data between host computers (local network or online service).

20. Glue that holds the Internet Together Listed are Five of the most important pieces of Hardware Hardware - designed to transmit data between networks 1.Hubs - link groups of computers to one another and let computers communicate with one another 2.Bridges - link local area networks (LANs) with one another  Enable data destined for another LAN to be sent there, while keeping local data inside its own network. 3.Gateways- translate data from one type of network to another. 4.Repeaters- amplify the data at intervals so the signal doesn’t weaken 5.Routers- manage Internet traffic  Ensures the data arrive at the proper destination Hub Repeater Router
