PACKET OPERATION
1Packet is a unit of data transmitted as a whole from one
2computer to another on a network. Packets can be
3transmitted on radio waves as well as on communications lines. Besides a transceiver and a
4computer, all you need is a terminal node controller
5(TNC). A TNC converts packets to audio tones and vice
6versa as one of its tasks. This transceiver has a

A variety of packet applications developed by hams
8include packet bulletin board systems (PBBSs). PBBSs
9are created and maintained by volunteers called a
10System Operator (SysOp). You may access one of your local PBBSs to send
11various useful information. Thousands of PBBSs, which
12have formed a worldwide network, relay
