DSSS		Direct Sequence Spread Spectrum is a modulation scheme employed
		by the 802.11b standard that uses a chipping code (redundant bit)
		during its transmission to reject interference.
Dynamic IP Address		It is an IP address that is dynamically allocated or assigned to a client
		device within a TCP/IP network, typically by a DHCP server.
Encryption		Encryption is a security method applying specific algorithms to make
		sure that all the data from one computer is encoded into a form that
		only the other intended party will be able to decode and view the
		information.
Ethernet		An IEEE standard network protocol that specifies how data is
		transmitted over a common medium. It uses CSMA/CD, which stands
		for Carrier Sense Multiple Access with Collision Detection. It has a
		defined data rate of 10Mbps.
Fast Ethernet		An IEEE standard extended from 10Base-T Ethernet to support 100Mbps
		data rate.
Firewall		It is a software layer that controls network access from within and
		without so that any undesired activity by malicious or snooping parties
		may be prevented.
Firmware		It is a software code written and saved within the read-only memory
		(ROM) or programmable read-only memory (PROM). The firmware that
		is written on the ROM/PROM is retained even when the device is
		powered off.
FTP		File Transfer Protocol. It is a protocol designed to transfer files over a
		TCP/IP network.
Full Duplex		It defines the ability of a device to transmit data simultaneously in both
		upstream and downstream directions over a single line.
Gateway		A gateway is a device that interconnects networks.
Half Duplex		It defines the ability of a device to transmit in one direction at a time
		over a single line.
HTTP		HyperText Transport Protocol is a common protocol used to connect
		servers on the World Wide Web, with its primary function being to
		establish a connection with a web server and transmit HTML pages to
		the client’s browser.
ICMP		Internet Control Message Protocol is a message control and error
		reporting protocol between a host server and a gateway to the
		Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages
		are processed by the IP software and are not directly apparent to the
		application user.
IGMP		Internet Group Management Protocol is the standard for IP
		multicasting on the Internet. It is used to establish host memberships in
		particular multicast groups on a single network. The mechanisms of the
		protocol allow a host to inform its local router, using Host Membership
		Reports, that it wants to receive messages addressed to a specific
