A type of computer processing in which the computer responds immediately to user requests. Each request is considered to be a transaction. Automatic teller machines for banks are an example of transaction processing.
The opposite of transaction processing is batch processing, in which a batch of requests is stored and then executed all at one time. Transaction processing requires interaction with a user, whereas batch processing can take place without a user being present.
Short for transmitter-receiver, a device that both transmits and receives analog or digital signals. The term is used most frequently to describe the component in local-area networks (LANs) that actually applies signals onto the network wire and detects signals passing through the wire. For many LANs, the transceiver is built into the network interface card […]
The process of converting a media file or object from one format to another. Transcoding is often used to convert video formats (i.e., Beta to VHS, VHS to QuickTime, QuickTime to MPEG). But it is also used to fit HTML files and graphics files to the unique constraints of mobile devices and other Web-enabled products. […]
A device that is actuated by energy from one system and supplies energy usually in another form to a second system. For example, a microphone is a transducer that transforms sound energy into electrical signals.
(adj.) A type of LCD screen in which the pixels are illuminated from both the front of the monitor��s screen and from behind the screen, combining the illumination characteristics of both transmissive and reflective technologies. Transflective LCDs work under any lighting condition, from complete darkness to bright sunlight.
A device composed of semiconductor material that amplifies a signal or opens or closes a circuit. Invented in 1947 at Bell Labs, transistors have become the key ingredient of all digital circuits, including computers. Today’s microprocessors contains tens of millions of microscopic transistors. Prior to the invention of transistors, digital circuits were composed of vacuum […]
