Driver A piece of software developed to interface a piece of hardware
with its immediate upper-layer software (i.e. operating system) so
that it can be recognized and operated.
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 intended party will be able to decode to 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 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) of the device so that it 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.
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 router 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
