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 radio system is one type of wireless data transmission, and it is a wireless media that transfers data by carrying electromagnetic waves with low frequencies to distant locations through an electrical conductor and an antenna.
