Universal Product Code. A relatively complex numeric
symbology. Each character consists of two bars and two
spaces, each of which is any of four widths. The standard
symbology for retail food packages in the United States.
User Datagram Protocol. A protocol within the IP protocol
suite that is used in place of TCP when a reliable delivery is
not required. For example, UDP is used for real-time audio
and video traffic where lost packets are simply ignored,
because there is no time to retransmit. If UDP is used and a
reliable delivery is required, packet sequence checking and
error notification must be written into the applications.
A solid state device which produces visible laser light.
Wide-Area Network. A radio network that supports data
communication beyond a local area. That is, information
can be sent across a city, state, or even nationwide.
A warm boot restarts the mobile computer by closing all
running programs. All data that is not saved to flash
memory is lost.
Wired Equivalent Privacy, is specified by IEEE for encryption
and decryption of RF (wireless) communications.
