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

It is an IP address that is dynamically allocated or assigned to a client

Address

 

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
