Glossary of Terms

802.11b: A wireless networking standard that supports data encryption and up
to 11Mbps bandwidth.
Authentication: The process of verifying a user on a network is who they say
they are and preventing unauthorized users from network access.
Bandwidth: A measure of the rate at which data can be sent and received
through the network. This value is usually given in bits per second (bps)
or Megabits per second (Mbps).
CIF (Common Intermediate Format): An intermediate video format. When
DVC-1100 video is transmitted over a network, the sizes will be CIF,
QCIF, or SQCIF. The VideoPhone will default to CIF. CIF resolution is
352 x 288.
Data Encryption: Encoding network traffic so users without proper decryption
rights cannot properly decode the data.
DHCP (Dynamic Host Configuration Protocol): A protocol that network devices
use to obtain an IP address, subnet mask, gateway and DNS addresses
automatically. A DHCP server can be a router, ISP server, or PC running
Internet connection sharing. See Static IP address.
Directory Service: A service that allows users to make videoconferencing
calls with telephone numbers. It does this by correlating telephone
numbers to actual public IP addresses.
DNS (Domain Name System): A system used to translate computer names
into IP addresses. For example, a DNS server would translate
www.dlink.com
DSL (Digital Subscribers Line): A technology that delivers digital information
at a high speed through a user's telephone line. The most common
DSL is ADSL (Asymmetrical Digital Subscribers Line) where the
download speed is usually much higher than the upload speed.
Ethernet: The port on the back of the DVC-1100 VideoPhone that is used to
send and receive data over a network.
