Our Definition

 

A packet is a piece of a data block that is transmitted from one computer to another via a network where, at its destination, it reassembles into that data block. Each packet contains data regarding its destination and its sequential number so that it can be properly reassembled.

 

Packets were a technology developed by Norman Abramson with the AlohaNet. The AlohaNet network technology broke data transmissions into small blocks called packets, that were reassembled at the recipient's site.

Web-o-pedia

"A piece of a message transmitted over a packet-switching network. See under packet switching. One of the key features of a packet is that it contains the destination address in addition to the data. In IP networks, packets are often called datagrams."

 

Smart Computing

"A block of data transmitted from one computer to another on a network or on the Internet. A packet contains three parts: the data to be transmitted, the data needed to guide the packet to its destination, and the data that corrects errors that occur along the way. Several packets make up a typical transmission. The computer splits up the transmission at the transmission point and reassembles it at the destination."
