on another user's machine. These peer-to-peer networks are often simpler to
install and manage, but dedicated servers provide better performance and can
handle higher transaction volume. Multiple servers are used in large networks.
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.
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.
