PCMCIA
(Personal Computer Memory Card International Association)
The Personal Computer Memory Card International Association (PCMCIA), develops
standards for PC cards, formerly known as PCMCIA cards. These cards are available
in three types, and are about the same length and width as credit cards. However, the
different width of the cards ranges in thickness from 3.3 mm (Type I) to 5.0 mm (Type
II) to 10.5 mm (Type III). These cards can be used for various functions, including
memory storage, land line modems and wireless modems.
PPP (Point-to-Point Protocol)
PPP is a protocol for communication between computers using a serial interface, typically
a personal computer connected by phone line to a server.
PPPoE (Point-to-Point Protocol over Ethernet)
Point-to-Point Protocol is a method of secure data transmission. PPP using Ethernet to
connect to an ISP.
Preamble
Allows you to set the preamble mode for a network to Long, Short, or Auto.
The default preamble mode is Long.
Radio Frequency (RF) Terms: GHz, MHz, Hz
The international unit for measuring frequency is Hertz (Hz), equivalent to the older
unit of cycles per second. One megahertz (MHz) is one million Hertz. One gigahertz
(GHz) is one billion Hertz. The standard US electrical power frequency is 60 Hz, the
AM broadcast radio frequency band is 0.55-1.6 MHz, the FM broadcast radio frequency
band is 88-108 MHz, and wireless 802.11 LANs operate at 2.4 GHz.
SSID (Service Set Identifier)
SSID is a group name shared by every member of a wireless network. Only client PCs
with the same SSID are allowed to establish a connection. Enabling the Response to
Broadcast SSID requests option allows the device to broadcast its SSID in a wireless
network. This allows other wireless devices to scan and establish communication with
the device. Unchecking this option hides the SSID to prevent other wireless devices
from recognizing and connecting to the device.
Station
Any device containing IEEE 802.11 wireless medium access conformity.
Subnet Mask
A subnet mask is a set of four numbers configured like an IP address. It is used to create
IP address numbers used only within a particular network.
