Error correcting technique used to correct errors in data
bursts. |
| SNR |
Signal to Noise Ratio |
Compares the desired transmission signal to background noise on a
transmission line. The higher the ratio, the better the signal transmission
is. |
| SSID |
Service Set Identifier |
Is the name of your wireless network. When you search for a
wireless network from a wireless client the network name that appears is the
SSID. CenturyLink uses "myCenturyLinkxxxx" and "CenturyLinkxxxx" as default
SSID's. The "xxxx" in the default SSID represents the last four digits of your
routers serial number making network identification easier. |
| TCP |

Manages a data stream across the Internet ensuring a reliable
delivery. |
| TKIP |

Allows network devices to send short datagrams to each other
without the reliability of TCP. |
| URL |
Uniform Resource Locator |
Standard way of defining where a resource is available on the
Internet. If you are looking for CenturyLink on the Internet, the URL
www.CenturyLink.com would be used to connect to CenturyLink. |
| USB |

has a maximum bus rate of 12Mbps where USB 2.0 has a maximum bus rate of
480Mbps. |
| VCI |
Virtual Channel Identifier |
Unique identifier in the ATM world identifying the virtual
channel a data stream should take. VCI works in conjunction with the VPI to
identify the destination point of the data stream. |
| VIP |
Virtual IP Interface |

Network covering a wide area providing connectivity for many
LANs. The Internet is considered a big WAN. |
| WEP |
Wired Equivalent Privacy |
Wireless network security protocol providing wireless security
with an AP. WEP has been replaced with WPA2 as the preferred wireless security
protocol for wireless networks. |
| WMM |
Wireless Multimedia |
Provides traffic QoS on the wireless link of a LAN. WMM allows
for the prioritization of traffic by traffic type on the wireless AP. |
| WPA / WPA2 |
Wi-Fi Protected Access |
Wireless network security protocol providing wireless security
with an AP. WPA2 is the preferred wireless security type over WEP. WPA2 allows
you to create a security phrase instead of having to develop a hexadecimal key
with WEP. |
