PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL
providers for connecting personal computers to a broadband modem for
Internet access. It is similar to how a dial-up connection works but at higher
speeds and quicker access.
PPTP (Point-to-Point Tunneling Protocol) - A protocol (set of communication
rules) that allows corporations to extend their own corporate network through
private "tunnels" over the public Internet. Effectively, a corporation uses a
wide-area network as a single large local area network. A company no longer
needs to lease its own lines for wide-area communication but can securely use
the public networks. This kind of interconnection is known as a virtual private
network.
RJ-11 (Registered Jack-11) - A telephone connector that holds up to four
wires. The RJ-11 the common connector used to plug the handset into the tele-
phone and the telephone into the wall.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Static IP Address - A permanent IP address that is assigned to a node in a
TCP/IP network.
Static Routing - Forwarding data in a network via a fixed path. Static routing
cannot adjust to changing line conditions as can dynamic routing.
Subnet Mask - The method used for splitting IP networks into a series of sub-
groups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the
basic communication language or protocol of the Internet. It can also be used
as a communications protocol in a private network (either an intranet or an
extranet). When you are set up with direct access to the Internet, your comput-
er is provided with a copy of the TCP/IP program just as every other computer
that you may send messages to or get information from also has a copy of
TCP/IP.
IPCONFIG - A utility that provides for querying, defining and managing IP
addresses within a network. A commonly used utility for configuring networks
with static IP addresses.
IPSec - IPSec (Internet Protocol Security) is a developing standard for securi-
ty at the network or packet processing layer of network communication. A big
advantage of IPSec is that security arrangements can be handled without
requiring changes to individual user computers.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as Web site
building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
MAC Address - The MAC (Media Access Control) address is your computer's
unique hardware number.
mIRC - mIRC runs under Windows and provides a graphical interface for log-
ging onto IRC servers and listing, joining and leaving channels.
NAT - NAT (Network Address Translation) is the translation of an Internet
Protocol address (IP address) used within one network to a different IP address
known within another network. One network is designated the inside network
and the other is the outside.
Packet Filtering - Discarding unwanted network traffic based on its originat-
ing address or range of addresses or its type (e-mail, file transfer, etc.).
PCMCIA - The PCMCIA (Personal Computer Memory Card International
Association) is an industry group organized in 1989 to promote standards for a
credit card-size memory or I/O device that would fit into a personal computer,
usually a notebook or laptop computer.
Ping - (Packet INternet Groper) An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by send-
ing out a packet and waiting for a response.
