Data Package

A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switch network. When any file (e-mail message, HTML file, Graphics file, and so forth) is sent from one place to another on the Internet, the TCP/IP divides the file into "chunks" of an efficient size for routing. Each of these packets is 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 (by the TCP layer at the receiving end).
