- Packet - A segment of data sent from one computer or network device to another computer or network device over a network. Packets may contain such information as its source, destination, size and other useful information, helping the packet get to its destination.
- Port - When referring to a network or to the Internet, a software or network port is a location where information is sent through.

Network switches are capable of inspecting data packets as they are received, determining the source and destination device of that packet, and forwarding it appropriately. By delivering each message only to the connected device it was intended for, a network switch conserves network bandwidth and offers generally better performance than a hub. - Switches
- Tarpit - Historically, a tarpit attempts to bog down a known spam site (determined by DNSBL) by delaying the response to a connection attempt. Currently, for NG Firewall, tarpit is a somewhat of a misnomer because connection attempts from sites in the DNSBL are immediately rejected. DSNBL
