  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. Coding theory - Wikipedia

    en.wikipedia.org/wiki/Coding_theory

    "The fundamental problem of communication is that of reproducing at one point, either exactly or approximately, a message selected at another point." With it came the ideas of the information entropy and redundancy of a source, and its relevance through the source coding theorem;

  5. 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}}} ;

  6. Data stream - Wikipedia

    en.wikipedia.org/wiki/Data_stream

    Fraud detection & scoring – raw data is used as source data for an anti-fraud algorithm (data analysis techniques for fraud detection). For example, timestamps, cookie occurrences or analysis of data points are used within the scoring system to detect fraud or to make sure that a message receiver is not a bot (so-called Non-Human Traffic [5]).

  7. 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 ...

  8. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    One example is the Linux kernel's EDAC subsystem (previously known as Bluesmoke), which collects the data from error-checking-enabled components inside a computer system; besides collecting and reporting back the events related to ECC memory, it also supports other checksumming errors, including those detected on the PCI bus.

  9. Network throughput - Wikipedia

    en.wikipedia.org/wiki/Network_throughput

    To determine the actual data rate of a network or connection, the "goodput" measurement definition may be used. For example, in file transmission, the "goodput" corresponds to the file size (in bits) divided by the file transmission time. The "goodput" is the amount of useful information that is delivered per second to the application layer ...
