5-10 SECTION 5, GLOSSARY

TCP/IP

The Transmission Control Protocol/Internet Protocol suite

provides standards and rules for data communication between

networks on the Internet. It is the worldwide Internetworking

standard and the basic communications protocol of the Internet.

Tunnel

To place packets inside other packets to send over a network.

The protocol of the enclosing packet is understood by each

endpoint, or tunnel interface, where the packet enters and exits

the network. VPNs rely on tunneling to create a secure network.

Tunneling requires the following protocol types:

! A carrier protocol, such as TCP, used by the network that the

data travels over

! An encapsulating protocol, such as IPSec, L2F, L2TP, or

PPTP, that is wrapped around the original data

! A passenger protocol, such as IP, for the original data

UDP

User Datagram Protocol. A method used along with the IP to

send data in the form of message units (datagram) between

network devices over a LAN or WAN.

Unicast

A point-to-point data transmission sent from one sender to one

receiver. This the normal way you access websites. See also

multicast.

UPnP

Universal Plug and Play

USB

Universal Serial Bus is a computer interface for add-on devices

such as printers, scanners, mice, modems, or keyboards.

USB 1.1 supports data transfer rates of 12 Mbps and plug-and-

play installation. You can connect up to 127 devices to a single

USB port.
