Transmitting Information
How is the information sent?
- Information -- email, web pages, phone calls, etc. -- are broken up into small units, called packets
- Think of sending a long message to a friend in Australia using postcards … write a few sentences on each postcard, number them as you write them, and mail
- Your friend gets lots of postcards, probably on different days and out of order, and so must reassemble them to put the message back together
- This scheme is called the Transmission Control Protocol and Internet Protocol, or TCP/IP
