PPTP		Point-to-Point Tunneling Protocol supports the creation of Virtual Private
		Networks by ensuring that messages transmitted from one VPN node
		to another are secure. Users can use PPTP to dial in to their corporate
		network via the Internet.
Preamble		A preamble is a signal used in network communications to synchronize
		the transmission timing between two or more systems. Proper timing
		ensures that all systems are interpreting the start of the information
		transfer correctly. While a short preamble improves throughput, a long
		preamble ensures compatibility.
RJ-45		A connector used for Ethernet devices that holds up to eight wires.
Short Slot Time		A reduced short slot time decreases backoff, or the length of waiting
		time before sending a packet on the LAN, thus improving throughput.
SNMP		Simple Network Management Protocol is a monitoring and controlling
		protocol. SNMP devices/applications report network activity within to a
		workstation console so that it may be monitored and controlled.
Subnet Mask		Subnet masking is a method of splitting IP networks into subgroups.
TCP		Transmission Control Protocol enables two hosts to establish a
		connection and exchange streams of data, guaranteeing delivery of
		data and that packets will be delivered in the same order in which
		they were sent.
Throughput		It is the measurable amount of data moved from one place to another
		within a given time period.
UConfig		The uConfig is a unique feature that provides the ability to directly
		access web-configurable Ethernet devices without the need to know
		absolute IP addresses. This feature is standard on all the devices that
		feature web-based configuration.
UDP		User Datagram Protocol is a connectionless protocol that, like TCP, runs
		on top of IP networks. Unlike TCP/IP, UDP provides a direct way to send
		and receive datagrams over an IP network and is used primarily for
		broadcasting messages over a network.
Unicasting		Communication that takes place over a network between a single
		sender and a single receiver.
URL		Uniform Resource Locator is the address that defines the location of a
		file on the World Wide Web.
UTP		Unshielded Twisted Pair is the most common kind of copper wiring
		designed to reduce crosstalk between copper wires.
VPN		Virtual Private Network is a secure means to join remote networks using
		comprehensive authentication and encryption. They may be
		“virtually” joined even across a public network like the Internet by using
		secure protocols like IPSec amongst others.
WAN		Wide Area Network. It is a communication network that extends over a
		large geographical area.
