Window random access memory (WRAM) - (high-speed video memory)
Wired Equivalent Privacy (WEP) - (First attempt at a wireless security protocol which used an encryption algorithm, although was considered weak, as it was susceptible to attacks.)
wireless access point (WAP) - (Commonly called an access point (AP), a wireless access point is a low-power, directional transceiver (transmitter/receiver) device that is connected to the local area network (LAN) through a standard network connection. The WAP associates with wireless devices within its immediate vicinity and transmits packets from the wired network to the wireless device.)
Wireless Application (Access) Protocol (WAP) - (A set of protocols proposed by mobile industry companies, such as Ericsson, Motorala, and Nokia, and introduced in 1999, intended to standardize the way different wireless devices and technologies, such as mobile phones, radio transceivers, and systems software, communicate, using types of communication, such as e-mail, newsgroups, and instant messaging.)
Wireless Ethernet Compatibility Alliance (WECA) - (industry standards organization - now the Wi-Fi Alliance)
Wireless Fidelity (Wi-Fi) - (generic term for wireless connection - wireless network products/certification standard)
Wireless Internet Service Provider (WISP) - (wireless broadband Internet provider)
Wireless Internet Service Providers Association (WISPA) - (wireless provider organization)
wireless intrusion detection system (WIDS) - (A system typically implemented on an existing wireless LAN infrastructure which receives wireless transmitted packets, analyzes the packets, correlates the packets against existing IT policy standards, and alerts the WIDS administrator if there is a violation. A WIDS may be simply a workstation with an antenna running a specialized sniffing application.)
wireless intrusion prevention system (WIPS) - (A system typically implemented on an existing wireless LAN infrastructure which receives wireless transmitted packets, analyzes the packets, correlates the packets against existing IT policy standards, and alerts the WIPS administrator if there is a violation. A WIPS may be simply a workstation with an antenna running a specialized sniffing application.)
