Computer Hardware Terms, Glossary and Dictionary

Packet, maybe called datagram in some cases, is a unit of a message transmitted over a packet-switching network. Data is broken up into packets for sending over a packet switching network. Each packet has a header containing its source and destination, a block of data content, and an error-checking code. All the data packets related to a message may not take the same route to get to their destination; they are reassembled once they have arrived.
