	ZyAIR 100 Wireless PC Card
Cryptoanalysis	The act of analyzing (or breaking into) secure documents or systems that are protected with
	encryption.
DCE	Data Communications Equipment is typically a modem or other type of communication
	device. The DCE sits between the DTE (data terminal equipment) and a transmission circuit
	such as a phone line.
Decryption	The act of restoring an encrypted file to its original state.
Directional	An antenna that concentrates transmission power into a direction thereby increasing coverage
Antennae	distance at the expense of coverage angle. Directional antenna types include yagi, patch and
	parabolic dish.
Direct	A type of spread spectrum radio transmission that spreads its signal continuously over a wide
Sequence	frequency band.
Spread
Spectrum
(DSSS)
DRAM	Dynamic RAM that stores information in capacitors that must be refreshed periodically.
DTE	Originally, the DTE (data terminal equipment) meant a dumb terminal or printer, but today it
	is a computer, or a bridge or router that interconnects local area networks.
EMI	ElectroMagnetic Interference. The interference by electromagnetic signals that can cause
	reduced data integrity and increased error rates on transmission channels.
Encryption	The act of substituting numbers and characters in a file so that the file is unreadable until it is
	decrypted. Encryption is usually done using a mathematical formula that determines how the
	file is decrypted.
ESSID	(Extended Service Set IDentification) The ESSID identifies the Service Set the station is to
	connect to. Wireless clients associating to the Access Point must have the same ESSID.
Ethernet	A very common method of networking computers in a LAN. There are a number of
	adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates of 10
	Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable and fiber-optic cable. The
	latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.
Events	These are network activities. Some activities are direct attacks on your system, while others
	might be depending on the circumstances. Therefore, any activity, regardless of severity is
	called an event. An event may or may not be a direct attack on your system.
FAQ	(Frequently Asked Questions) – FAQs are documents that list and answer the most common
	questions on a particular subject.
FCC	The FCC (Federal Communications Commission) is in charge of allocating the
	electromagnetic spectrum and thus the bandwidth of various communication systems.
Flash Memory	The nonvolatile storage that can be electrically erased and reprogrammed so that data can be
	stored, booted and rewritten as necessary.
Gateway	A gateway is a computer system or other device that acts as a translator between two systems
	that do not use the same communication protocols, data formatting structures, languages
	and/or architecture.
