• Asynchronous serial communication — describes an asynchronous, serial transmission protocol in which a start signal is sent prior to each byte, character or code word and a stop signal is sent after each code word. The start signal serves to prepare the receiving mechanism for the… …   Wikipedia

• Asynchronous serial interface — Asynchronous Serial Interface, or ASI, is streaming data format which often carries an MPEG Transport Stream (MPEG TS).It is electrically identical to an SDI signal and is always 270Mbit/s. There are two transmission formats commonly used by the… …   Wikipedia

• Serial communication — In telecommunication and computer science, serial communication is the process of sending data one bit at one time, sequentially, over a communication channel or computer bus. This is in contrast to parallel communication, where several bits are… …   Wikipedia

• Asynchronous communication — In telecommunications, Asynchronous communication is transmission of data without the use of an external clock signal. Any timing required to recover data from the communication symbols is encoded within the symbols. The most significant aspect… …   Wikipedia

• Universal asynchronous receiver/transmitter — A universal asynchronous receiver/transmitter (usually abbreviated UART and pronEng|ˈjuːɑrt) is a type of asynchronous receiver/transmitter , a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly… …   Wikipedia

• serial communications —    The transmission of information from computer to computer or from computer to peripheral device one bit at a time.    Serial communications can be synchronous and controlled by a clock, or they can be asynchronous and coordinated by start and… …   Dictionary of networking

• Parallel communication — In telecommunication and computer science, parallel communication is a method of sending several data signals simultaneously over a communication link (comprising of several wired channels in parallel) at one time. It contrasts with serial… …   Wikipedia

• Comparison of synchronous and asynchronous signalling — Synchronous and asynchronous transmissions are two different methods of transmission synchronization. Synchronous transmissions are synchronized by an external clock, while asynchronous transmissions are synchronized by special signals along the… …   Wikipedia

• Asynchrony — Asynchrony, in the general meaning, is the state of not being synchronized. * Asynchronous learning * Collaborative editing systemsIn specific terms of digital logic and physical layer of communication, an asynchronous process does not require a… …   Wikipedia
