I've noticed that occasionally after eating foods high in carbs (usually a big bowl of cereal) I'll start to pass out a couple hours after eating. If I'm lying down, it's very difficult not to pass out.
Packet radio is a form of packet switching technology used to transmit digital data via radio or wireless communications links. It uses the same concepts of data transmission via Datagram that are fundamental to communications via the Internet, as opposed to the older techniques used by dedicated or switched circuits.
The most common use of packet radio today is in amateur radio, to construct wireless computer networks. Its name is a reference to the use of packet switching between network nodes. Packet radio networks use the AX.25 data link layer protocol, derived from the X.25 protocol suite and adapted for amateur radio use.
