DSL Modem:
DSL stands for Digital Subscriber Line. A DSL modem uses your 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:
IP stands for Internet Protocol. An IP address consists of a series of four numbers
separated by periods, which identifies a single, unique Internet computer host in an IP network. Example: 192.168.2.1. It
consists of 2 portions: the IP network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded decimal numbers separated by “.”:
aaa.aaa.aaa.aaa, where each “aaa” can be anything from 000 to 255, or as four cascaded binary numbers separated by “.”:
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 consecutive leading
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also be described simply as “x” number of
leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP address that correspond to 1’s in the network
mask become part of the IP network address, and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, and its host ID is,
00000000.00000000.00000000.00000111. This is a convenient and efficient method for routers to route IP packets to their
destination.
ISP Gateway Address:
(see ISP for definition). The ISP Gateway Address is an IP address for the Internet router located at
the ISP's office.
ISP:
Internet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals and other
businesses or organizations.
LAN:
Local Area Network. A LAN is a group of computers and devices connected together in a relatively small area (such as a
house or an office). Your home network is considered a LAN.
MAC Address:
MAC stands for Media Access Control. A MAC address is the hardware address of a device connected to a
network. The MAC address is a unique identifier for a device with an Ethernet interface. It is comprised of two parts: 3 bytes of
