default gateway:
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
toward the destination.
dhcp:
The Dynamic Host Configuration Protocol automatically gives
every computer on your home network an IP address.
dns server ip address:
The domain Name System allows Internet
servers to have a domain name (such as www.Broadbandrouter.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 when typing “Broadbandrouter.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 Modem:
A digital Subscriber line modem uses existing phone
lines to transmit data at high speeds.
ethernet:
A standard for computer networks. ethernet networks are
connected by special cables and hubs, and move data around at up
to 10/100 million bits per second (Mbps).
idle timeout:
Idle Timeout is designed so that after there is no traffic
to the Internet for a pre-configured amount of time, the connection
will automatically be disconnected.
ip address and network (subnet) Mask:
An Internet Protocol address
consists of a series of four numbers — separated by periods — that
identifies a single, unique Internet computer host in an IP network.
As an example, 192.168.2.1 consists of two sections: the IP network
address and the host identifier. The IP address is a 32-bit binary
pattern that can be represented as four cascaded decimal numbers
separated by periods: aaa.aaa.aaa.aaa, where each “aaa” can be
anything from 000 to 255; or as four cascaded binary numbers
separated by periods: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb,
where each “b” can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of
