Transmission Control Protocol/Internet Protocol

(TCP/IP)

Protocol suite that includes TCP as the primary transport protocol, and IP as the
network layer protocol.

UTP

Unshielded twisted-pair cable.

Virtual LAN

(VLAN)

A Virtual LAN is a collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network. A VLAN
serves as a logical workgroup with no physical barriers, allowing users to share
information and resources as though located on the same LAN.
