A packet is the basic unit of data that

sent from one place to another on the
Internet, the file is divided into
"chunks" of an efficient size for

separately numbered and includes
the Internet address of the
destination. The individual packets
for a given file may travel different
routes through the Internet. When
they have all arrived, they are
reassembled into the original file at
the receiving end.
