	Glossary

socket	The association of a port with an IP address, serving as an identification of sender
	or recipient.
stack	The software code which implements the protocol being used. In the case of the
	NOE modules it is TCP/IP.
STP	Shielded Twisted Pair. A type of cabling consisting of several strands of wire
	surrounded by foil shielding, twisted together.
subnet	A physical or logical network within an IP network, which shares a network address
	with other portions of the network.
subnet mask	Used to indicate which bits in an IP address identify a subnet.
switch	A network device which connects two or more separate network segments and
	allows traffic to be passed between them. A switch determines whether a frame
	should be blocked or transmitted based on its destination address.

T

TCP	Transmission Control Protocol.
TCP/IP	A protocol suite consisting of the Transmission Control Protocol and the Internet
	Protocol; the suite of communications protocols on which the Internet is based.

U

UDP	User Datagram Protocol. A protocol which transmits data over IP.
URL	Uniform Resource Locator. The network address of a file.
UTP	Unshielded Twisted Pair. A type of cabling consisting of insulated cable strands
	which are twisted together in pairs.

W

Winsock	The Microsoft implementation of the Windows Sockets networking API based on
	the Berkeley UNIX Sockets interface for supporting TCP/IP.
