Glossary 183 Wireless Network A network that requires minimal cabling, as data is transmitted over the air using wireless adapters and wireless routers. Wire Map Tester It is used to test for opens, shorts, and crossed pairs. Wiretapping Gaining physical access to a network cable and cutting or piercing the cable so that the wires inside the cable can be accessed and then spliced or tapped.
