UDP is a communications protocol that offers limited service for exchanging data in a
network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control
Protocol (TCP). The advantage of UDP is that it is not required to deliver all data and may drop
network packets when there is e.g. network congestion. This is suitable for live video, as there is
no point in re-transmitting old information that will not be displayed anyway.
Universal Plug and Play (UPnP) is a set of networking protocols for primarily residential
networks without enterprise class devices that permits networked devices, such as personal
computers, printers, Internet gateways, Wi-Fi access points and mobile devices to seamlessly
discover each other's presence on the network and establish functional network services for data
sharing, communications, and entertainment.
Uniform Resource Locator or Unified Resource Locator (URL) is a character string that
specifies where a known resource is available on the Internet and the mechanism for retrieving it.
Wireless Application Protocol (WAP) is a technical standard for accessing information
over a mobile wireless network. A WAP browser is a web browser for mobile devices such as
mobile phones (called "cellular phones" in some countries) that uses the protocol.
Web server is a program, which allows Web browsers to retrieve files from computers
connected to the Internet. The Web server listens for requests from Web browsers and upon
receiving a request for a file sends it back to the browser.
The primary function of a Web server is to serve pages to other remote computers;
consequently, it needs to be installed on a computer that is permanently connected to the Internet.
It also controls access to the server whilst monitoring and logging server access statistics.
Wireless LAN is a wireless local area network that uses radio waves as its carrier: where
the network connections for end-users are wireless. The main network structure usually uses
cables.
