Packet

A packet refers to a unit of data that is logically grouped and contains the payload (information to be transmitted), originator, destination, and synchronizing information. The main aim of using packets is to transmit them over a network, allowing each packet to be sent along the most efficient route to reach its intended destination. On one end of the communication, packets are assembled, and on the receiving end, they are reassembled based on the header addressing information at the front of each packet. Routers within the network will store and forward packets based on network delays, errors, and re-transmittal requests from the receiving end.
