  2. Data communication - Wikipedia

    en.wikipedia.org/wiki/Data_communication

    Data communication, including data transmission and data reception, is the transfer of data, transmitted and received over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires , optical fibers , wireless communication using radio spectrum , storage media and computer buses .

  3. Signal transmission - Wikipedia

    en.wikipedia.org/wiki/Signal_transmission

    Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or packet of data, a phone call, or an email.

  4. Analog transmission - Wikipedia

    en.wikipedia.org/wiki/Analog_transmission

    Analog transmission is a transmission method of conveying information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that information. It could be the transfer of an analog signal , using an analog modulation method such as frequency modulation (FM) or amplitude modulation (AM), or no ...

  6. Data stream - Wikipedia

    en.wikipedia.org/wiki/Data_stream

    Attributes – each attribute [3] of the data stream represents a certain type of data, e.g. segment / data point ID, timestamp, geodata. Timestamp attribute helps to identify when an event occurred. Subject ID is an encoded-by-algorithm ID, that has been extracted out of a cookie .

  7. Signal - Wikipedia

    en.wikipedia.org/wiki/Signal

    A common example is signal transmission between different locations. The embodiment of a signal in electrical form is made by a transducer that converts the signal from its original form to a waveform expressed as a current or a voltage , or electromagnetic radiation , for example, an optical signal or radio transmission .

  8. Unit interval (data transmission) - Wikipedia

    en.wikipedia.org/wiki/Unit_interval_(data...

    The unit interval is the minimum time interval between condition changes of a data transmission signal, also known as the pulse time or symbol duration time.A unit interval (UI) is the time taken in a data stream by each subsequent pulse (or symbol).

  9. Channel capacity - Wikipedia

    en.wikipedia.org/wiki/Channel_capacity

    Here is the formal definition of each element (where the only difference with respect to the nonfeedback capacity is the encoder definition): W {\displaystyle W} is the message to be transmitted, taken in an alphabet W {\displaystyle {\mathcal {W}}} ;
