Glossary of terms

Dynamic Host Configuration Protocol. This protocol automatically 
configures the TCP/IP settings of every computer on your home 
network.

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 stands for Digital Subscriber Line. A DSL modem uses your existing 
phone lines to transmit data at high speeds. 

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).

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 stands for Internet Protocol.
An IP address consists of a series of four numbers separated by periods, 
that identified a single, unique Internet computer host.
Example: 192.34.45.8.

Internet Service Provider. An ISP is a business that provides connectivity 
to the Internet for individuals and other businesses or organizations.

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.

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 stands for Media Access Control.
A MAC address is the hardware address of a device connected to a 
network.

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.

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.

A networking device that connects multiple networks together.

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.

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.

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).

Transmission Control Protocol/Internet Protocol. This is the standard 
protocol for data transmission over the Internet.

WAN stands for Wide Area Network. A network that connects 
computers located in geographically seperate areas, (i.e., different 
buildings, cities, countries). The Internet is a wide area network.

WPS stands for Wifi Protected Setup. It is a feature allowing to register 
easily a device to a WiFi Access Point with security automatically 
enabled. The advantage is no need for the user to enter a long and 
complicated security key.
