DHCP (Dynamic Host Configuration Protocol) A protocol used to automatically assign an IP address to each device on a network. DHCP server This server dynamically manages a pool of IP addresses for use on a network or the Internet. When a user logs in, the server "loans" the user an IP address for the duration of the network connection. When a user logs off, the IP address is returned to the pool for use by another device. Digital Certificate An electronic means of proving the identity of a network user or device. Certificates contain detailed information about the user's device in a standard format. Digital certificates are typically issued by a trusted thirdparty Certificate Authority (CA). Locally administered, or self-signed, certificates are valid in some instances. 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. 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). Encryption A network security that encodes the data sent across a wireless network making the data unintelligible to unauthorized users. The printer supports WEP and WPA. 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 straight-through cable with an RJ-45 plug to connect the printer to an Ethernet network. Ethernet A popular form of wired computer networking for Local Area Networks. EWS (embedded Web server) A server that is completely contained within a device. An EWS provides management information about the device. This is helpful for managing single devices on a small network. By using a Web browser to access an EWS, network users can perform such operations as obtaining network printer status updates, simple troubleshooting, and changing device configuration setting. Firewall A combination of hardware and software tools that protects a network from unwanted entry. 42 Glossary ENWW
