On LANs trunking is done with either the ISL (Inter-Switch Link) or 802.1q protocols. The interface would need to support whatever trunking protocol that switch was using. Most PCs' NICs do not support trunking but you can buy NICs that do. They are typically used in servers which need to be connected to more than one vlan. The port the PC plugs into on the switch needs to configured as a access link if it doesn't have a NIC that supports trunking.
