  2. powercfg - Wikipedia

    en.wikipedia.org/wiki/Powercfg

    powercfg must be run from an elevated command prompt, and, under Windows XP, it requires workstation Administrator or power user rights. Power Schemes are configured on a per-user basis. The most common cause of problems with power saving and hibernation on Windows systems is an incompatible device driver.

  3. Status register - Wikipedia

    en.wikipedia.org/wiki/Status_register

    A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.

  4. Word problem (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Word_problem_(mathematics)

    Note that the rewriting here is one-way. The word problem is the accessibility problem for symmetric rewrite relations, i.e. Thue systems. [27] The accessibility and word problems are undecidable, i.e. there is no general algorithm for solving this problem. [28]

  5. User error - Wikipedia

    en.wikipedia.org/wiki/User_error

    Another similar term used in the United States military is "operator headspace and timing issue" or "OHT," borrowing terminology related to the operation of the M2 Browning machine gun. [ 17 ] "(It's a) carbon based error", indicates a user problem (as humans are a carbon-based life-form), as opposed to a silicon one.

  6. Word problem for groups - Wikipedia

    en.wikipedia.org/wiki/Word_problem_for_groups

    The word problem was one of the first examples of an unsolvable problem to be found not in mathematical logic or the theory of algorithms, but in one of the central branches of classical mathematics, algebra. As a result of its unsolvability, several other problems in combinatorial group theory have been shown to be unsolvable as well.

  7. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    Order of operations. In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations.

  8. Dyscalculia - Wikipedia

    en.wikipedia.org/wiki/Dyscalculia

    Visual-spatial input, auditory input, and touch input will be affected due to these processing errors. Dyscalculics may have a difficult time adding numbers in a column format because their mind can mix up the numbers, and it is possible that they may get the same (wrong) answer twice due to their mind processing the problem incorrectly.

  9. Idempotence - Wikipedia

    en.wikipedia.org/wiki/Idempotence

    Pressing the On button (green) is an idempotent operation, since it has the same effect whether done once or multiple times. Likewise, pressing Off is idempotent. Idempotence ( UK : / ˌ ɪ d ɛ m ˈ p oʊ t ən s / , [ 1 ] US : / ˈ aɪ d ə m -/ ) [ 2 ] is the property of certain operations in mathematics and computer science whereby they can ...
