Web server
A web server provides HTML documents (web pages).
WEP
Wired Equivalent Privacy (WEP) is an encryption protocol for
WLANs. The key length is 40 or 104 bits.
WINS
The Windows Internet Name Service (WINS) is a translation of the
NetBIOS over TCP/IP network protocol by Microsoft. Like DNS,
WINS is used for centralised name resolution. See also DNS.
WLAN
Wireless Local Area Network (Wireless LAN, WLAN) refers to a loc-
al wireless network based on the 802.11 standard.
WMM
Wi-Fi Multimedia (WMM) prioritises the data packets from different
applications, thus improving the transmission of voice, music and
video data in WLAN networks. To do this, WMM provides quality-
of-service features (QoS) for IEEE 802.11-based networks.
WPA
Wi-Fi-Protected Access (WPA) is an encryption protocol for WLANs.
WPA uses dynamic keys that are based on the Temporal Key Integ-
rity Protocol (TKIP).
WPA 2
Wi-Fi Protected Access (WPA) is an encryption protocol for WLANs.
WPA 2 uses AES.
WPA Enterprise
With WPA 1 / 2, WPA Enterprise enables subscribers to be authen-
ticated using the Extensible Authentication Protocol (EAP). After
successful authentication, the server transfers a shared key to the
client and the access point for data transfer in the WLAN.
WPA-PSK
With WPA 1 / 2, WPA-PSK enables subscribers to be authenticated
using pre-shared keys. The access point and the client use the
same string for the key calculation in the WLAN. This string needs to
be configured by the users.
X.25
X.25 is a standardised series of protocols for wide area networks
(WANs) via the telephone network.
X.31
The X.31 standard describes the connecting of ISDN and X.25 sys-
tems. It is a standard for connecting card terminals.
X.500
The X.500 standard describes the setting up of a directory ser-
vice. See also LDAP.
X.509
The X.509 standard describes the generating of certificates for a
public key insfrastructure (PKI).
X.75
X.75 is a standardised series of protocols for ISDN networks with a
