AAM6000EV-M ADSL Combo Router User's Manual ISP LAN LED MAC address mask Mbps NAT NAT rule network network mask NIC packet ping port POTS host ID uniquely identifying the host itself on that network. A network mask is used to define the network ID and the host ID. Because IP addresses are difficult to remember, they usually have an associated domain name that can be specified instead. See also domain name, network mask. Internet Service Provider A company that provides Internet access to its customers, usually for a fee. Local Area Network A network limited to a small geographic area, such as a home, office, or small building. Light Emitting Diode An electronic light-emitting device. The indicator lights on the front of the AAM6030VI are LEDs. Media Access Control address The permanent hardware address of a device, assigned by its manufacturer. MAC addresses are expressed as six pairs of characters. See network mask. Abbreviation for Megabits per second, or one million bits per second. Network data rates are often expressed in Mbps. Network Address Translation A service performed by many routers that translates your network's publicly known IP address into a private IP address for each computer on your LAN. Only your router and your LAN know these addresses; the outside world sees only the public IP address when talking to a computer on your LAN. A defined method for translating between public and private IP addresses on your LAN. A group of computers that are connected together, allowing them to communicate with each other and share resources, such as software, files, etc. A network can be small, such as a LAN, or very large, such as the Internet. A network mask is a sequence of bits applied to an IP address to select the network ID while ignoring the host ID. Bits set to 1 mean "select this bit" while bits set to 0 mean "ignore this bit." For example, if the network mask 255.255.255.0 is applied to the IP address 100.10.50.1, the network ID is 100.10.50, and the host ID is 1. See also binary, IP address, subnet, "IP Addresses Explained" section. Network Interface Card An adapter card that plugs into your computer and provides the physical interface to your network cabling, which for Ethernet NICs is typically an RJ-45 connector. See Ethernet, RJ-45. Data transmitted on a network consists of units called packets. Each packet contains a payload (the data), plus overhead information such as where it came from (source address) and where it should go (destination address). Packet Internet (or Inter-Network) Groper A program used to verify whether the host associated with an IP address is online. It can also be used to reveal the IP address for a given domain name. A physical access point to a device such as a computer or router, through which data flows into and out of the device Plain Old Telephone Service The basic service providing standard single line telephones, telephone line and access to the public switched network. PPP Point-to-Point Protocol A protocol for serial data transmission that is used to carry IP (and other protocol) 62
