UARTUniversal Asynchronous Receiver/Transmitter, is a computer component that handles asynchronous serial communication. Every computer contains a UART to manage the serial ports. As modems have become increasingly fast, the UART has come under greater scrutiny as the cause of transmission bottlenecks, therefore make sure your PC has a 16550 UART if you have a fast external modem. UATUser Acceptance Testing, also called application testing or end-user testing, is a phase of software development in which the software is tested in the real world by its intended audience. UAT is often the last phase of the software testing process and is performed before the tested software is released to its intended market. UAVUnmanned Aerial Vehicle. UDDIUniversal Description, Discovery and Integration. A Web-based distributed directory that enables business to list themselves on the Internet and discover each other, similar to a traditional phone book's yellow and white pages. UDPUser Datagram Protocol, a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It's used primarily for broadcasting messages over a network. UGCUser Generated Content. UMLUnified Modeling Language, a general-purpose notational language for specifying and visualising complex software, especially large, object-oriented projects. UMTSUniversal Mobile Telecommunications System. UNCUniversal Naming Convention or Uniform Naming Convention, a PC format for specifying
the location of resources on a LAN. UNC uses the following format:
\\server-name\shared-resource-pathname So, for example, to access the file test.txt
in the directory etc on the shared server gray, you would write:
\\gray\etc\test.txt UnicodeStandard character set compatible with many languages. UNIXA multi-user, multi-tasking, operating system developed in the 70's. It was able to run on any computer that had a C compiler. It is still very much used by today's web developers. unsubscribe rateAn unsubscribe rate indicates the percentage of customers who have unsubscribed or opted out of a mailing list after an email campaign. UploadingTransfering files to the Internet or network so to be accessed via a web browser. UPSUninterruptible Power Supply or Uninterruptible Power Source, is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. URIUniform Resource Identifier. URLUniversal Resource Locator - most commonly seen in the form of a web page address, but can point to any usable resource on the internet, e.g. graphics files and other media. USBUniversal Serial Bus, is an external bus standard that supports data transfer rates of
480Mbps. A single USB port can be used to connect up to 127 peripheral devices, such as
mice, modems, and keyboards. USB also supports Plug-and-Play installation and hot
plugging. USENETA Bulletin Board system where each collection of posted notes is known as a newsgroup. Utility ComputingA service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Similar to On Demand Computing . USSDUnstructured Supplementary Service Data, is a GSM communication technology that is used to send text between a mobile phone and an application program in the network. USSD is similar to Short Messaging Service, but, unlike SMS, USSD transactions occur during the session only. UTPUnshielded Twisted Pair. Copper wiring used in small-to-large networks to connect host devices to hubs and switches. UUCPUNIX-to-UNIX Copy Protocol. A method of communicating between different UNIX systems for the copying of files and sending commands to be executed on another system. UXGAUltra Extended Graphics Array, a display specification that is capable of displaying 1600 x 1200 resolution, or approximately 1.9 million pixels. |
