The Internet Protocol
v How is the information sent?
o Information -- email, web pages, phone calls, everything
sent over the internet -- is  broken up into small units,
called packets
o Packets contain an IP address, a sequence number and
some actual information, a part of the whole message
o This scheme is called the Transmission Control Protocol
and Internet Protocol, or TCP/IP
o The packets are sent independently, usually taking
different routes, and reassembled at the destination to
reconstruct the original message
