HP Deskjet 6800 series printer User's Guide Broadcast packet: A packet sent from one device on a network to all devices on the network. c Channel: One of several pre-set frequencies at which 802.11b-enabled devices communicate in order to reduce interference. The number of channels available varies by country/region. d DHCP (Dynamic Host Configuration Protocol): A protocol used to automatically assign an IP address to each device on a network. e EAP: Extensible Authentication Protocol (EAP) is a general protocol for authentication that also supports multiple authentication methods, such as token cards, one-time passwords, certificates, and public key authentication. WPA uses EAP. Encryption: A network security that encodes the data sent across a wireless network making the data unintelligible to eavesdroppers. The printer supports WEP, TKIP, and AES. Encryption keys: A sequence of characters or digits that a wireless device uses to encode data. Encryption keys can be static (as they are in WEP) or dynamic (as they are in WPA). Ethernet: A popular form of wired computer networking for Local Area Networks. Ethernet cable: There are two types of Ethernet cables. A straight-through cable is the most common and is used to connect devices on a network to a hub or router. A crossover cable is used to connect two devices that have Ethernet ports but that are not hubs or routers. Use a CAT-5 cable with an RJ-45 plug to connect the printer to an Ethernet network. f Firewall: A combination of hardware and software tools that protects a network from unwanted entry. g Gateway: A dedicated device (router or computer) that connects two different networks. For example, a computer on an Ethernet network may act as a gateway between the network and the Internet. h Host name: The name by which the printer identifies itself on the network. The printer's host name appears on the HP Report page. Use the host name to open the printer's embedded Web server (EWS). 44
