The Internet is a Packet Switched Network--messages are sent
as packets.
Messages are sent across the web using the TCP/IP protocols
Transmission Control Protocol (TCP) breaks up the messages
and puts on header information regarding the order of packets
and for error checking.
Internet Protocol (IP) addresses the packets and sends them
across the internet. The packets donít all necessarily follow
the same route or arrive in the correct order. IP unpacks the
packets at their destination.
TCP puts the packets in their proper order at the end.
