HOW IT WORKS
Just as each letter has an address on it, packets have
headers that enable them to reach their destination.
PACKETS
Each packet is labeled with a header. The
header is like a luggage tag. It contains address
information that is used to determine where to
send the packet as it travels through the Internet.
Different packets from the same message may
take different routes to reach the destination.
When the packets all reach their destination, the
information they contain is put back together
into a message. The use of packets enables
fast delivery of messages through the Internet.
Messages are unpacked and recreated so quickly
that the sharing of information seems instant.
