DNS - Domain Name System (DNS). The distributed name/address
mechanism used in the Internet.
DOCSIS - Known as CableLabs Certified Cable Modems, DOCSIS (Data
Over Cable Service Interface Specifications) is a standard interface for
cable modems, the devices that handle incoming and outgoing data
signals between a cable TV operator and a personal or business computer
or television set.
Domain - A subnetwork comprised of a group of clients and servers under
the control of one security database. Dividing LANs into domains improves
performance and security.
Download - To receive a file transmitted over a network. In a
communications session, download means receive, and upload means
transmit.
DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a redundant
bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that
the original data can be recovered. Even if one or more bits in the chip
are damaged during transmission, statistical techniques embedded in the
radio can recover the original data without the need for retransmission. To
an unintended receiver, DSSS appears as low power wideband noise and is
rejected (ignored) by most narrowband receivers.
Dynamic IP Address - An IP address that is automatically assigned to
a client station in a TCP/IP network, typically by a DHCP server. Network
devices that serve multiple users, such as servers and printers, are usually
assigned static IP addresses.
Dynamic Routing - The ability for a Router to forward data via a different
route based on the current conditions of the communications circuits. For
example, it can adjust for overloaded traffic or failing lines and is much
more flexible than static routing, which uses a fixed forwarding path.
Encapsulation - The wrapping of data in a particular protocol header. For
example, Ethernet data is wrapped in a specific Ethernet header before
network transit.
Encryption - Applying a specific algorithm to data in order to alter the
data’s appearance and prevent other devices from reading information.
