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.
Packet-switched describes the type of network in which relatively small units of data called packets are routed through a network based on the destination address contained within each packet. Breaking communication down into packets allows the same data path to be shared among many users in the network.
