DHCP (Dynamic Host Configuration Protocol) - A networking protocol that allows
administrators to assign temporary IP addresses to network computers by "leasing" an IP
address to a user for a limited amount of time, instead of assigning permanent IP addresses.
DHCP Clients - An Internet host using DHCP to obtain configuration parameters, such as a
network address.
DHCP Server - An Internet host that returns configuration parameters to DHCP clients.
DNS (Domain Name Server) - The IP address of your ISP's server, which translates the names of
websites into IP addresses.
Domain - A specific name for a network of computers.
Download - To receive a file transmitted over a network.
DSL (Digital Subscriber Line) - An always-on broadband connection over traditional phone
lines.
DSCP (DiffServe Code Point) provides a method of tagging IP packets with QoS priority
information.
Dynamic IP Address - A temporary IP address assigned by a DHCP server.
EIGRP (Enhanced Interior Gateway Routing Protocol) - Provides fast convergence, support for
variable-length subnet mask, and supports multiple network layer protocols.
Encryption - Encoding data transmitted in a network.
Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved
from a common transmission medium.
Firmware - The programming code that runs a networking device.
Flow Control - Enables lower speed devices to communicate with higher speed devices. This
feature is implemented by the higher speed device refraining from sending packets.
FTP (File Transfer Protocol) - A protocol used to transfer files over a TCP/IP network.
Full Duplex - The ability of a networking device to receive and transmit data simultaneously.
GARP (General Attributes Registration Protocol) - Registers client stations into a multicast
domain.
Gateway - A device that interconnects networks with different, incompatible communications
protocols.
GBIC (GigaBit Interface Converter) - A hardware module used to attach network devices to
fiber-based transmission systems. GBIC converts the serial electrical signals to serial optical
signals and vice versa.
GVRP (GARP VLAN Registration Protocol) - Registers client stations into a VLANs.
