  2. Ones' complement - Wikipedia

    en.wikipedia.org/wiki/Ones'_complement

    The ones' complement of a binary number is the value obtained by inverting (flipping) all the bits in the binary representation of the number. The name "ones' complement" [1] refers to the fact that such an inverted value, if added to the original, would always produce an "all ones" number (the term "complement" refers to such pairs of mutually additive inverse numbers, here in respect to a ...

  3. Signed number representations - Wikipedia

    en.wikipedia.org/wiki/Signed_number_representations

    Therefore, ones' complement and two's complement representations of the same negative value will differ by one. Note that the ones' complement representation of a negative number can be obtained from the sign–magnitude representation merely by bitwise complementing the magnitude (inverting all the bits after the first). For example, the ...

  4. Method of complements - Wikipedia

    en.wikipedia.org/wiki/Method_of_complements

    In the decimal numbering system, the radix complement is called the ten's complement and the diminished radix complement the nines' complement. In binary, the radix complement is called the two's complement and the diminished radix complement the ones' complement. The naming of complements in other bases is similar.

  5. Serial binary adder - Wikipedia

    en.wikipedia.org/wiki/Serial_binary_adder

    The serial binary subtractor operates the same as the serial binary adder, except the subtracted number is converted to its two's complement before being added. Alternatively, the number to be subtracted is converted to its ones' complement, by inverting its bits, and the carry flip-flop is initialized to a 1 instead of to 0 as in addition. The ...

  6. Internet checksum - Wikipedia

    en.wikipedia.org/wiki/Internet_checksum

    The checksum field is the 16 bit one's complement of the one's complement sum of all 16 bit words in the header. For purposes of computing the checksum, the value of the checksum field is zero. If there is no corruption, the result of summing the entire IP header, including checksum, and then taking its one's complement should be zero.

    Universe set and complement notation The notation L ∁ = def X ∖ L . {\displaystyle L^{\complement }~{\stackrel {\scriptscriptstyle {\text{def}}}{=}}~X\setminus L.} may be used if L {\displaystyle L} is a subset of some set X {\displaystyle X} that is understood (say from context, or because it is clearly stated what the superset X ...

  8. Man's Search for Meaning - Wikipedia

    en.wikipedia.org/wiki/Man's_Search_for_Meaning

    Man's Search for Meaning is a 1946 book by Viktor Frankl chronicling his experiences as a prisoner in Nazi concentration camps during World War II, and describing his psychotherapeutic method, which involved identifying a purpose to each person's life through one of three ways: the completion of tasks, caring for another person, or finding meaning by facing suffering with dignity.

  9. Dunning–Kruger effect - Wikipedia

    en.wikipedia.org/wiki/Dunning–Kruger_effect

    Some researchers include a metacognitive component in their definition. In this view, the Dunning–Kruger effect is the thesis that those who are incompetent in a given area tend to be ignorant of their incompetence, i.e., they lack the metacognitive ability to become aware of their incompetence.
