CPE
Customer Premises Equipment, such as ADSL router, USB modem.
Default Gateway (Router)
Every non-router IP device needs to configure a default gateway’s IP address.
When the device sends out an IP packet, if the destination is not on the same
network, the device has to send the packet to its default gateway, which will then
send it out towards the destination.
DHCP
Dynamic Host Configuration Protocol, this protocol automatically gives every
computer on your home network an IP address.
DNS Server IP Address
DNS stands for Domain Name System, which allows Internet servers to have a
domain name (such as www. ADSLrouter.com) and one or more IP addresses
(such as 192.34.45.8). A DNS server keeps a database of Internet servers and
their respective domain names and IP addresses, so that when a domain name
is requested (as in typing " ADSLrouter.com" into your Internet browser), the user
is sent to the proper IP address. The DNS server IP address used by the
computers on your home network is the location of the DNS server your ISP has
assigned to you.
DSL
Digital Line Subscriber (DSL) technology provides high-speed access over
twisted copper pair for connection to the Internet, LAN interfaces, and to DSL
services such as video-on-demand, distance learning, and video conferencing.
Ethernet
It is a standard for computer networks. Ethernet networks are connected by
special cables and hubs or switches, and move data around at up to 10/100
million bits per second (Mbps).
