Glossary of terms
DHCP – Dynamic Host Configuration Protocol. This protocol automatically
configures the TCP/IP settings of every computer on your home network.
DNS Server Address – DNS stands for Domain Name System, which allows
Internet host computers to have a domain name and one or more IP addresses.
A DNS server keeps a database of host computers and their respective domain
names and IP addresses, so that when a domain name is requested, the user is sent to
the proper IP address. The DNS server address used by the computers on your
home network is the location of the DNS server your ISP has assigned.
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 million bits per second
(Mbps).
HPNA – Home Phone Line Networking Alliance, which is an association of
corporations (including ) working to ensure the adoption of a single, unified phone
line networking standard. Your Home Connect home network gateway is compliant
with HPNA Specification 2.0, which allows networking speeds of up to 1 million bits
per second (Mbps) using your existing home phone lines.
IP Address – IP stands for Internet Protocol. An IP address consists of a series of
four numbers separated by periods, that identifies an single, unique Internet computer
host. Example: 192.34.45.8.
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. This address is required
only when using a cable or DSL modem.
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 –MACstands for Media Access Control. A MAC address is the
hardware address of a device connected to a network.
NAT – Network Address Translation. This process allows all of the computers on
your home network to use one IP address. Using the NAT capability of the Home
Connect home network gateway, you can access the Internet from any computer on
your home network without having to purchase more IP addresses from your ISP.
PPPoE – Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method
of secure data transmission originally created for dial-up connections; PPPoE is for
Ethernet connections.
Secondary Dial-Up – A secondary dial-up phone number is used by your ISP in
case your primary dial-up number has too many other customers accessing it.
The secondary dial-up phone number will be used if your primary dial-up phone
number cannot be accessed.
SPI – Stateful Packet Inspection. SPI is the type of corporate-grade Internet security
provided by your Home Connect home network gateway. Using SPI, the gateway acts
as a “firewall”, protecting your network from computer hackers.
Subnet Mask – A subnet mask, which may be a part of the TCP/IP information
provided by your ISP, is a set of four numbers configured like an IP address. It is used
to create IP address numbers used only within a particular network (as opposed to
valid IP address numbers recognized by the Internet, which must assigned by
InterNIC).
TCP/IP – Transmission Control Protocol/Internet Protocol. This is the standard
protocol for data transmission over the Internet.
WAN – Wide Area Network. A network that connects computers located in
geographically separate areas, (i.e., different buildings, cities, countries). The Internet
is a wide area network.
