Paul Baran of RAND Corporation
"Packet switching is the breaking down of data
into datagrams or packets that are labeled to
indicate the origin and the destination of the
information and the forwarding of these packets
from one computer to another computer until the
information arrives at its final destination
computer. This was crucial to the realization of
a computer network. If packets are lost at any
given point, the message can be resent by the
originator."
