Thicknet Connections

Thicknet cable is connected to a network using a device called a transceiver. This device includes a piece of equipment that actually pierces the cable to connect to it. This connector is known as a vampire tap or a piercing tap. A computer's NIC can then be connected to the transceiver using a special transceiver cable.
