  2. Error detection and correction - Wikipedia

    en.wikipedia.org/wiki/Error_detection_and_correction

    A checksum of a message is a modular arithmetic sum of message code words of a fixed word length (e.g., byte values). The sum may be negated by means of a ones'-complement operation prior to transmission to detect unintentional all-zero messages.

  3. Block code - Wikipedia

    en.wikipedia.org/wiki/Block_code

    The rate of a block code is defined as the ratio between its message length and its block length: = /. A large rate means that the amount of actual message per transmitted block is high.

  4. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.

  5. Error management theory - Wikipedia

    en.wikipedia.org/wiki/Error_management_theory

    Socially unrestricted male and female high school students were found to report being more subject to sexual harassment as well as sexually harassing others. [5] From this, it is possible that being subject to sexual over-perception may explain the link between socio-sexuality and being subject to sexual harassment .

  6. False positives and false negatives - Wikipedia

    en.wikipedia.org/wiki/False_positives_and_false...

    A false negative error, or false negative, is a test result which wrongly indicates that a condition does not hold. For example, when a pregnancy test indicates a woman is not pregnant, but she is, or when a person guilty of a crime is acquitted, these are false negatives.

  7. ECC memory - Wikipedia

    en.wikipedia.org/wiki/ECC_memory

    One 64 GiB DDR5-4800 ECC 1.1 V RDIMM. Registered, or buffered, memory is not the same as ECC; the technologies perform different functions. It is usual for memory used in servers to be both registered, to allow many memory modules to be used without electrical problems, and ECC, for data integrity.

  8. Error correction model - Wikipedia

    en.wikipedia.org/wiki/Error_correction_model

    ECMs are a theoretically-driven approach useful for estimating both short-term and long-term effects of one time series on another. The term error-correction relates to the fact that last-period's deviation from a long-run equilibrium, the error, influences its short-run dynamics. Thus ECMs directly estimate the speed at which a dependent ...

    en.wikipedia.org/wiki/Quiz_bowl

    Some tournaments, such as College Bowl, are criticized for being insufficiently academic, including using superfluous clues in their questions, and for recycling questions from previous years. [ 4 ] [ 13 ] The use of "hoses," misleading clues that discourage players from buzzing in too early, is also considered a mark of "bad" quiz bowl.
