	ZyAIR 100 Wireless PC Card
	install traffic or mail filters. Routers are also prone to attacks because they contain a great deal
	of information about a network.
RTS Threshold	Transmitter contending for the medium may not hear each other. RTS/CTS mechanism can
	solve this “Hidden Node Problem.” If the packet size is smaller than the preset RTS
	Threshold size, the RTS/CTS mechanism will not be enabled.
Server	A computer, or a software package, that provides a specific kind of service to client software
	running on other computers.
Service Set	The SSID indicates the identity of an ESS or IBSS.
Identifier (SSID)
Snooping	Passively watching a network for information that could be used to a hacker’s advantage, such
	as passwords. Usually done while Camping Out.
SPAM	Unwanted email, usually in the form of advertisements.
SSL (Secured	Technology that allows you to send information that only the server can read. SSL allows
Socket Layer)	servers and browsers to encrypt data as they communicate with each other. This makes it very
	difficult for third parties to understand the communications.
Station (STA)	Any device that contains an IEEE 802.11 conformant medium access control (MAC) and
	physical layer (PHY) interface to the wireless medium (WM).
Telnet	Telnet is the login and terminal emulation protocol common on the Internet and in UNIX
	environments. It operates over TCP/IP networks. Its primary function is to allow users to log
	into remote host systems.
Terminal	A device that allows you to send commands to a computer somewhere else. At a minimum,
	this usually means a keyboard and a display screen and some simple circuitry.
Terminal	Software that pretends to be (emulates) a physical terminal and allows you to type commands
Emulation	to a computer somewhere else.
Software
UNIX	A widely-used operating system in large networks.
URL	(Uniform Resource Locator) URL is an object on the Internet or an intranet that resides on a
	host system. Objects include directories and an assortment of file types, including text files,

Vulnerability	Point where a system can be attacked.
WAN	Wide Area Networks link geographically dispersed offices in other cities or around the globe.
	Just about any long-distance communication medium can serve as a WAN link, including
	switched and permanent telephone circuits, terrestrial radio systems and satellite systems.
Wired	The optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to
Equivalent	provide data confidentiality that is subjectively equivalent to the confidentiality of a wired
Privacy (WEP)	local area network (LAN) medium that does not employ cryptographic techniques to enhance
	privacy.
