 **GPIO - General Purpose Input/Output** - A bank of spare input and/or output pins on a computer module which are reserved for user applications. Examples would be the BBC Micro's User Port, or the Raspberry Pi's dual-row 40-pin "GPIO" pins. **GPIO - General Purpose Input/Output** - A bank of spare input and/or output pins on a computer module which are reserved for user applications.

 **MSK** - Minimum Shift Keying, A variant of AFSK, where the frequencies used are selected to ensure there is no phase shift at the transition from one bit to the next. This reduces high-frequency harmonics in the transmission. **MSK** - Minimum Shift Keying, A variant of AFSK, where the frequencies used are selected to ensure there is no phase shift at the transition from one bit to the next.

 **NET/ROM** - NET/ROM (Networking over Radio Operations and Management) is both a network layer (OSI L3) protocol, which allows for the routing of packets between different nodes, and a transport layer (OSI L4) protocol that provides reliable delivery of packets and error correction. It adds reliability and efficiency capabilities such as automatic routing, link quality monitoring, and congestion control. A NET/ROM node user may display a list of other known network nodes; establish a transport-level circuit to a distant node; and connect to another end-user or mailbox in the vicinity of that distant node. **NET/ROM** - NET/ROM (Networking over Radio Operations and Management) is both a network layer (OSI L3) protocol, which allows for the routing of packets between different nodes, and a transport layer (OSI L4) protocol that provides reliable delivery of packets and error correction.
