Synchronous literally means "at the same time," but in spectrum analysis, synchronous components are defined as spectral components that are integral multiples, or harmonics, of a fundamental frequency They may in some cases exist as multiples of an integral fraction of the fundamental frequency, in which case they are called sub harmonics
"a synchronous set of clocks"; "the synchronous action of a bird's wings in flight"; "synchronous oscillations" (digital communication) pertaining to a transmission technique that requires a common clock signal (a timing reference) between the communicating devices in order to coordinate their transmissions
1) Pertaining to an event that happens, exists, or arises at precisely the same time as another event 2) Pertaining to an operation that occurs regularly or predictably with regard to the occurrence of a specified event in another process; for example the calling of an input/output routine that receives control at a precoded location in a program
A type of message passing where the sending task waits for a reply before continuing processing For more information see the Cogent White Paper: Synchronous & Asynchronous Messages
(adj ) See also "asynchronous " Coinciding in time (Also called "real-time" Synchronous communication technologies require the simultaneous participation of the communicating parties Internet Chat and the bullhorn are two examples of synchronous communication technologies Neither is very effective if no listeners are present at the moment that the speaker holds forth
A method of transmitting data in which the data elements are sent at a specific rate so that start and stop characters are not needed Used by older modems, AmEx PIP terminals, etc Compare to Asynchronous
(digital communication) pertaining to a transmission technique that requires a common clock signal (a timing reference) between the communicating devices in order to coordinate their transmissions
Two-way communication, happening at the same time Internet chat rooms and desktop video conferencing systems are examples of synchronous communication involving computer technology
The transmission of data between a transmitting and receiving device occurs as a series of zeros and ones For the data to be "read" correctly, the receiving device must begin reading at the proper point in the series In synchronous communication, this coordination is accomplished by synchronizing the transmitting and receiving devices to a common clock signal (see Asynchronous)
Synchronous can refer to: (1) A communications method that transmits a group of characters as a block of data rather than as individual characters (2) A reference to the fact that two different data streams are tied, or synchronized, to a single reference clock (3) Data transmitted in a time-division multiplexer
occurring or existing at the same time or having the same period or phase; "recovery was synchronous with therapy"- Jour A M A ; "a synchronous set of clocks"; "the synchronous action of a bird's wings in flight"; "synchronous oscillations"
Occurring at the same time In a synchronous class, learners and the instructor in different locations use such technologies as instructional television or Web-based chat rooms to interact simultaneously
A form of communication transmission with a direct timing relationship between input and output signals The transmitter and receiver are in sync and signals are sent at a fixed rate Information is sent in multibyte packets It is faster than asynchronous character transmission, since start and stop bits are not required It is used for mainframe-to-mainframe and faster workstation transmission
A communication method in which the data flows continuously, without start and stop bits and the receiver must synchronize to the timing of the transmitter
Having a specific relationship to a time base or clock In synchronous communications, data characters are sent according to a timing signal which synchronizes the two communicating devices
in online learning, an event in which all of the participants are online at the same time and communicating with one another For example, an instructor might schedule a guest lecturer to take question at a particular time; all interested people would connect with the lecture when the guest is online Contrast with
This term, meaning 'coinciding in time', refers to communication which is carried out with all parties present at the same time, but not necessarily in the same physical location For example, a face-to-face or telephone conversation, a videoconference, and a chat-room discussion are all forms of synchronous communication
Type of transmission in which the transmission and reception of all data is synchronized by a common clock and the data is usually transmitted in blocks rather than individual characters Can also mean that the data stream has the same capacity in both directions
