CSMA/CD (Carrier Sense Multiple Access/Collision Detect)

The router used to forward all traffic not addressed to a station within the local subnet.
DHCP (Dynamic Host Configuration Protocol)
A utility for assigning TCP/IP addresses to workstations automatically (a unique IP address must be assigned to each computer in the network). When computers are moved within the network, DHCP allows automated IP addresses to be assigned automatically. DHCP “leases” an IP address to a device for a specific amount of time, which is useful in education and other environments where users change frequently. DHCP also supports static IP addresses for computers needing a permanent IP address, such as those containing Web servers. See static IP address.
DCHP Client
A device configured to receive a DHCP address.
DHCP Server
A device configured to assign IP addresses to DHCP clients.
DMZ (Demilitarized Zone)
Computer host or small network inserted as a “neutral zone” between a company’s private network and the external public network. It prevents outside users from having access to an internal server containing confidential data.
DMZ Hosting
Allows one IP address (or computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP address if you want to use DMZ Hosting.
