computers currently available and the IP address assigned to
each one.
DNS is an alternative system for name resolution suitable for
network computers with fixed IP addresses.
WLAN Wireless Local Area Network.
WMM Wi-Fi Multimedia (WMM), a Wi-Fi Alliance certified standard that
provides multimedia enhancements for Wi-Fi networks that
improve the user experience for audio, video, and voice
applications. This standard is compliant with the IEEE 802.11e
Quality of Service (QoS) extensions for 802.11 networks. WMM
provides prioritized media access by shortening the time between
