A wireless application protocol (WAP) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for internet access, including e-mail, the world wide web, newsgroups, and internet relay chat. A wap browser is a web browser for mobile devices such as mobile phones that uses the protocol.

War dialing is a technique of using a modem to automatically scan a list of telephone numbers, usually dialing every number in a local area code to search for computers, bulletin board systems (computer servers), and fax machines.

Wired equivalent privacy (WEP) is a security protocol for wireless local area networks defined in the standard ieee 802.11b. It was introduced as part of the original 802.11 standard ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network. WEP, recognizable by the key of 10 or 26 hexadecimal digits, was at one time widely in use and was often the first security choice presented to users by router configuration tools.

A windump is a freeware tool for windows that is a protocol analyzer that can monitor network traffic on a wire.

Wardriving is searching for wi-fi wireless networks by an individual in a moving vehicle while using a portable computer, smartphone, or personal digital assistant (PDA).

A whois is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an internet resource, such as a domain name, an IP address block, or an autonomous system. The protocol stores and delivers database content in a human-readable format. The whois protocol is documented in RFC 3912.

A worm is a computer program that can run independently, can propagate a complete working version of itself onto other hosts on a network, and may consume computer resources destructively.

A web server is a computer system that processes requests via HTTP, the basic network protocol used to distribute information on the world wide web. Web server is used to refer either the entire system, or specifically to the software that accepts and supervises the HTTP requests.

X.400 was originally published in 1984 by CCITT and later re-written in 1988 jointly by ISO and CCITT. X.400 is a standard that conforms to layer 7 of the osi and is a standard used for transporting e-mail messages. X.400 is an alternative standard to the commonly used SMTP and includes support for several transport connections including ethernet, TCP/IP, and dial-up.

XNS is short for Xerox Network Services, XNS is a proprietary network communications protocol developed by Xerox. XNS is no longer used and has been replaced by transmission control protocol / interface program (TCP/IP).
