which is implemented in the network adapters that are plugged into the machines. The actual
communications path is the cable (twisted pair, coax, optical fiber) that interconnects each
network adapter.
MAC Address - MAC (Media Access Control) A MAC address is the hardware address of a device
connected to a network.
MDI / MDI-X - Medium Dependent Interface - Also called an "uplink port," it is a port on a
network hub or switch used to connect to other hubs or switches without requiring a crossover
cable. The MDI port does not cross the transmit and receive lines, which is done by the regular
ports (MDI-X ports) that connect to end stations. The MDI port connects to the MDI-X port on
the other device. There are typically one or two ports on a device that can be toggled between
MDI (not crossed) and MDI-X (crossed).
Medium Dependent Interface – X (crossed) - A port on a network hub or switch that crosses the
transmit lines coming in to the receive lines going out.
MP3 – MPEG Audio Layer 3. This is an audio compression technology that is included in the
MPEG-1 and -2 specifications. MP3 encoding can allow you to compress CD-quality sound by a
factor of 12.
MPEG – Moving Pictures Experts Group. MPEG is a standard for compressing video. MPEG-1 can
provide resolution of 352x240 at 30 frames/second (fps) with 24-bit color and CD-quality sound.
MPEG-2 can provide resolution of 704x480. MPEG uses the same intraframe coding as JPEG for
individual frames, but also uses interframe coding which can help to further compress the video
data, thereby reducing the overall size of the video.
NAT – (Network Address Translation) This process allows all of the computers on your home
network to use one IP address. The NAT capability of the Barricade, allows you to access the
Internet from any computer on your home network without having to purchase more IP
addresses from your ISP. Network Address Translation can be used to give multiple users access
to the Internet with a single user account, or to map the local address for an IP server (such as
Web or FTP) to a public address. This secures your network from direct attack by hackers, and
provides more flexible management by allowing you to change internal IP addresses without
affecting outside access to your network. NAT must be enabled to provide multi-user access to
the Internet or to use the Virtual Server function.
Packet Binary Convulational Code(tm) (PBCC) - A modulation technique developed by Texas
Instruments Inc. (TI) that offers data rates of up to 22Mbit/s and is fully backward compatible
with existing 802.11b wireless networks.
PCI - Peripheral Component Interconnect - Local bus for PCs from Intel that provides a high-
speed data path between the CPU and up to 10 peripherals (video, disk, network, etc.). The PCI
bus runs at 33MHz, supports 32-bit and 64-bit data paths, and bus mastering.
PPPoE - 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.
Roaming - A function that allows your to move through a particular domain without losing
network connectivity.
Static IP - If your Service Provider has assigned a fixed IP address; enter the assigned IP
address, subnet mask and the gateway address provided by your service provider.
