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 The ISP Gateway Address is an IP address for the Internet router located at the
(see ISP for definition) 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 MAC stands 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.
RJ-45 Registered Jack-45, 8 wire connector
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.
