TCP/IP

Protocol

family on which the

Internet

is based.

IP

forms the basis for every computer-to-

computer connection.

TCP

provides applications with a reliable transmission link in the

form of a continuous data stream. TCP/IP is the basis on which services such as WWW,
Mail and News are built. There are other protocols as well.

URL
Universal Resource Locator
Globally unique address of a Domain on the

Internet

.

WAN
Wide Area Network
A WAN is a network that is not restricted to one particular area, such as the

Internet

. A

WAN is run by one or more public providers to enable private access. You access the
Internet via an

Internet Provider

.

WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the

IEEE 802.11

standard. It is used to protect wire-

less transmissions in a

WLAN

against unauthorised access through

Encryption

of the

data transmitted.

Wireless network

WLAN

WLAN
Wireless LAN
Wireless LANs enable network components to communicate with a network using radio
waves as the transport medium. A wireless LAN can be connected as an extension to a
wired LAN or it can form the basis for a new network. The basic element of a wireless
network is the cell. This is the area where the wireless communication takes place.
WLAN is currently specified in Standard

IEEE 802.11

. The Gigaset WLAN Repeater 108

complies with Standard 802.11g.

WPA
WPA was developed to improve the security provided by

WEP

. WPA uses complex proce-

dures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA
can use an authentication server (e.g. a RADIUS server) to increase security.

WPA-PSK
WPA Pre-shared Key
Variant of

WPA

data encryption, in which new keys are automatically generated at reg-

ular intervals by means of a keyword (Pre-shared Key). The key is updated after defined
periods (

Rekey Interval

).
