GLOSSARY

Ad-hoc

An ad-hoc network is a local area network or other small network, such as

wireless, in which some of the network devices are part of the network only for the

duration of a communications session. In the case of mobile and portable devices,

they can be a part of the network when in close proximity to the rest of the

network.

Cable Modem

A device that connects your PC to a local TV line and receives data at 1.5Mpbs.

One of its connections is connected to your PC and the other one is to the cable

wall outlet. It attaches a standard 10BASE-T Ethernet card to a computer and

modulates between digital and analog signals.

Cell

The radio coverage area for a wireless device to communicate with an Access

Point base station. The size of the cell can depend on the antenna, the speed of

transmission, and the physical area.

Channel

Each channel refers to a different frequency level allowing for multiple

communication paths through one device, much the same way a radio operates.

DHCP (Dynamic Host Configuration Protocol)

A protocol that centrally assigns IP addresses (often local IP addresses) to a

device in a TCP/IP network. Under TCP/IP, each device that can connect to the

Internet requires a unique IP address. Rather than having to set it manually to

each machine on the network, a DHCP server can automatically distribute IP

addresses from a central point. When a new computer is plugged into a different

place on the network, it is automatically given a new IP address. DHCP is

particularly useful for a company network where there are more computers than

available IP addresses.

DMZ

Abbreviation for Demilitarized Zone. It is an area between a computer’s private

network and its outside public network. DMZ prevents the external users from

accessing the internal private network directly.

DNS (Domain Name System)

The system in which an Internet domain name are located and translated into an

IP address. Domain names are basically an easy to remember handle for an

Internet address.

Domain Name

A name that identifies one or more IP addresses. For example, the domain name

"microsoft.com" represents many IP addresses. Domain names are used in URLs

to identify particular Web pages. For example, in the URL

http://www.macsense.com, the domain name is macsense.com.
