  3. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    This is sometimes called an inverse mask or a wildcard mask. When the value of the mask is broken down into binary (0s and 1s), the results determine which address bits are to be considered in processing the traffic. A 0-bit indicates that the address bit must be considered (exact match); a 1-bit in the mask is a "don't care". This table ...

  4. Wildcard mask - Wikipedia

    en.wikipedia.org/wiki/Wildcard_mask

    A wildcard mask can be thought of as an inverted subnet mask. For example, a subnet mask of 255.255.255.0 (11111111.11111111.11111111.00000000 2) inverts to a wildcard mask of 0.0.0.255 (00000000.00000000.00000000.11111111 2). A wild card mask is a matching rule. [2] The rule for a wildcard mask is: 0 means that the equivalent bit must match

  5. Bit field - Wikipedia

    en.wikipedia.org/wiki/Bit_field

    Most also support the use of the AND operator (&) to isolate the value of one or more bits. If the status-byte from a device is 0x67 and the 5th flag bit indicates data-ready. The mask-byte is 2^5 = 0x20. ANDing the status-byte 0x67 (0110 0111 in binary) with the mask-byte 0x20(0010 0000 in binary) evaluates to 0x20. This means the flag bit is ...

  6. Higher-order singular value decomposition - Wikipedia

    en.wikipedia.org/wiki/Higher-order_singular...

    In multilinear algebra, the higher-order singular value decomposition (HOSVD) of a tensor is a specific orthogonal Tucker decomposition. It may be regarded as one type of generalization of the matrix singular value decomposition. It has applications in computer vision, computer graphics, machine learning, scientific computing, and signal ...

  7. Church encoding - Wikipedia

    en.wikipedia.org/wiki/Church_encoding

    This list representation can be given type in System F. The evident correspondence to Church numerals is non-coincidental, as that can be seen as a unary encoding, with natural numbers represented by lists of unit (i.e. non-important) values, e.g. [() ()], with the list's length serving as the representation of the natural number.

  8. Short-circuit evaluation - Wikipedia

    en.wikipedia.org/wiki/Short-circuit_evaluation

    Short-circuit evaluation, minimal evaluation, or McCarthy evaluation (after John McCarthy) is the semantics of some Boolean operators in some programming languages in which the second argument is executed or evaluated only if the first argument does not suffice to determine the value of the expression: when the first argument of the AND function evaluates to false, the overall value must be ...

  9. Boolean expression - Wikipedia

    en.wikipedia.org/wiki/Boolean_expression

    In computer science, a Boolean expression (also known as logical expression) is an expression used in programming languages that produces a Boolean value when evaluated. A Boolean value is either true or false. A Boolean expression may be composed of a combination of the Boolean constants True/False or Yes/No, Boolean-typed variables, Boolean ...
