client/server network A network of two or more computers that rely upon a central server
to mediate the connections or provide additional system
resources. This dependence upon a server differentiates a client/
server network from a peer-to-peer network.
computer name A name that uniquely identifies a computer on the network so that
all its shared resources can be accessed by other computers on
the network. One computer’s name cannot be the same as any
other computer or domain name on the network.
crossover cable See Ethernet cable.
DHCP Acronym for “Dynamic Host Configuration Protocol.” A TCP/IP
protocol that automatically assigns temporary IP addresses to
computers on a local area network. Microsoft Broadband
Networking base stations support the use of DHCP which,
combined with ICS, allows you to share one Internet connection
with multiple computers on a network.
dial-up connection An Internet connection of limited duration that uses a public
telephone network rather than a dedicated circuit or some other
type of private network. The Microsoft Broadband Networking
hardware does not support the use of a dial-up connection to the
Internet.
DNS Acronym for “Domain Name System.” A data query service chiefly
used on the Internet for translating host names into Internet
addresses. The DNS database maps DNS domain names to IP
addresses, so that users can locate computers and services
through user-friendly names.
domain In a networked computer environment, a collection of computers
that share a common domain database and security policy. A
domain is administered as a unit with common rules and
procedures, and each domain has a unique name.
driver Within a networking context, mediates communication between a
computer and a network adapter installed on that computer.
DSL Acronym for “Digital Subscriber Line.” A constant, high-speed
digital connection to the Internet that uses standard copper
telephone wires.
DSL modem See broadband modem.
duplex A mode of connection; full-duplex transmission allows for the
simultaneous transfer of information between the sender and the
receiver. Half-duplex transmission allows for the transfer of
information in only one direction at a time.
dynamic IP address The IP address assigned (using the DHCP protocol) to a device that
requires it. A dynamic IP address can also be assigned to a router
by an ISP.
