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.
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.
Proxy - A proxy server sits between the client and the Internet. It can retrieve
requested files from its own cache or from a remote server. It is also used in
conjunction with a firewall and gateway to enhance security on a network.
Roaming - A function that allows your to move through a particular domain
without losing network connectivity.
