U
UDP (Users Datagram Protocol)
The user datagram protocol is a communication protocol between two com-
puters and an alternative to TCP (Transmission Control Protocol). As with
TCP, UDP communicates via Internet Protocol, although it is somewhat less
reliable due to its uncontrolled communication method.
URL (Uniform Resource Locator)
Address form for Internet files which are mostly applied within the World
Wide Web (WWW). The URL format makes a unique designation of all
documents on the internet possible. It describes the address of a document or
objects that can be read by a web browser. URL includes the transmission
type (HTTP, FTP), the computer that contains the information and the path
on the computer. A URL has the following format:
Document type://Computer name/List of contents/File name.
UTP (Unshielded Twisted Pair)
The UTP cable is a symmetrical, non-protected cable with twisted colored
wires in pairs. This cable type, either of a two-pair or four-pair design, is the
cable type most used for floor wiring and terminal wiring.
V

velopment, marketing and operation of BACnet components in a standard
