Access Point
A device that allows wireless clients to connect to one another. An access point can also act as a bridge between wireless clients and a “wired” network, such as an Ethernet network. Wireless clients can be moved anywhere within the cover- age area of the access point and remain connected to the network. If connected to an Ethernet network, the access point monitors Ethernet traffic and forwards appropriate Ethernet messages to the wireless network, while also monitoring wireless traffic and forwarding wireless client messages to the Ethernet network.
Client
A desktop or mobile computer connected to a network.
DHCP (Dynamic Host Configuration Protocol)
A protocol designed to automatically assign an IP address to every computer on a network.
DNS (Domain Name System) Server Address
Allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses so that when a user enters a domain name into a Web browser, the user is sent to the proper IP address. The DNS server address used by computers on the home network corresponds to the location of the DNS server the ISP has assigned.
DSL (Digital Subscriber Line) Modem
A modem that uses existing phone lines to transmit data at high speeds.
Encryption
