Packet Switching Store-and-Forward Transmission
To send a message from a source end system to a destination end system, the source breaks long messages into smaller chunks of data known as packets. Most packet switches use store-and-forward transmission at the inputs to the links. Store-and-forward transmission means that the packet switch must receive the entire packet before it can begin to transmit the first bit of the packet onto the outbound link. More ...
