- All computers on the Internet work together to transfer information back and forth around the world.
- TCP/IP - Computers on the Internet communicate using a common language called TCP/IP, which stands for Transmission Control Protocol/Internet Protocol.
- Like a moving company, TCP/IP packages and addresses information and then ensures that the information arrives safely at the intended destination.
- Packet - When you send information through the Internet, the information is broken down into smaller pieces, called packets. Each packet travels independently through the Internet and may take a different path to arrive at the intended destination.
- T1 and T3 - T1 and T3 are high speed computer lines for carrying information between huge computer systems on the Internet.
- Router - Routes are specialized computers that regulate the traffic on the Internet. A packet may pass through many routers before reaching its intended destination. Like a good travel agent, a router picks the most efficient route, based on the traffic and number of stopovers.
- Host - A host is any computer that is directly connected to the Internet.
- When information arrives at the intended destination, the packets are reassembled. If damaged, the computer that sent the packet is asked to send a new copy.
