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. The MAC address is a unique identifier for a device with an Ethernet interface.
It is comprised of two parts: 3 bytes of data that corresponds to the Manufacturer ID (unique for each
manufacturer), plus 3 bytes that are often used as the product's serial number.
NAT: Network Address Translation. This process allows all of the computers on your home network to use one
IP address. Using the broadband router's NAT capability, you can access the Internet from any computer on
your home network without having to purchase more IP addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network application/protocol over
another. Below is a list of common applications and protocol/port numbers:
Application
Telnet
FTP
SMTP
POP3
H.323
SNMP
SNMP Trap
HTTP
PPTP
PC Anywhere
PC Anywhere
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data transmission method
originally created for dial-up connections; PPPoE is for Ethernet connections. PPPoE relies on two widely
accepted standards, Ethernet and the Point-to-Point Protocol. It is a communications protocol for transmitting
information over Ethernet between different manufacturers
Protocol: A protocol is a set of rules for interaction agreed upon between multiple parties so that when they
interface with each other based on such a protocol, the interpretation of their behavior is well defined and can
be made objectively, without confusion or misunderstanding.
Router: A router is an intelligent network device that forwards packets between different networks based on
network layer address information such as IP addresses.
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 (e.g. 255.255.255.0) 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 be assigned by InterNIC).
