WEP is a protocol that adds security to wireless local area networks (WLANs) based on the 802.11 Wi-Fi standard. WEP is an OSI Data Link layer (Layer 2) security technology that can be turned "on" or "off." WEP was designed to give wireless networks the equivalent level of privacy protection as a comparable wired network.
WAP - the Wireless Application Protocol - defines a network architecture for content delivery over wireless networks. Central to the design of WAP is a network stack based on the OSI model. WAP implements several new networking protocols that perform functions similar to the well-known Web protocols HTTP, TCP, and SSL.
