MAC address In a network, the MAC address is a unique number that identifies a specific hardware interface. It is a 12-digit hexadecimal number. Modem A piece of network equipment that you use to gain access to the Internet - typically either DSL through your phone line or Cable service. Multicast Multicast is the communication of information to a group of destinations simultaneously. Multicast communication is between a single sender and multiple receivers on a network.

Physical ports allow you to connect network devices. For example, your VPortal has 4 ports on it. One Ethernet port, an Internet port where you can connect a modem and 2 phone ports where you can connect your telephones or fax machine. In TCP/IP networks, ports are logical connections. Every IP address is divided into ports. This allows one IP address to be used by multiple programs to send and receive data at the same time. Logical ports are assigned numbers that identify the type of port it is. For example, port 80 is used for HTTP traffic and port 110 is used for email. PPPoE Point to Point Protocol over Ethernet. PPPoE is a protocol for connecting users on an Ethernet LAN to the Internet through a DSL broadband connection. In addition to data transport, the DSL connection provides authentication through the use of a user name and password that you or your ISP has selected. Your V-Portal (or your current home networking equipment) stores this information and sends to your ISP. Your ISP then checks this information and lets you connect to the Internet through them. PPTP Point to Point Tunneling Protocol. PPTP is used to extend VPNs (Virtual Private Networks). A VPN is a private network of computers that uses the Internet to connect some nodes. PPTP allows companies to extend their VPNs by using private "tunnels" over the Internet. PPTP is used to ensure that messages are secure when they are transmitted through the tunnels from one VPN to another. Protocol A set of rules that, when followed, allows two devices to communicate. Proxy A computer that acts as a bridge between two other computers that use different standards, formats, or protocols. Router A network device that lets you connect more than one piece of equipment (like computers) to your DSL or cable modem to share one Internet connection.
