  2. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]

    en.wikipedia.org/wiki/Windows_Calculator

    Windows Calculator is a software calculator developed by Microsoft and included in Windows. In its Windows 10 incarnation it has four modes: standard, scientific, programmer, and a graphing mode. The standard mode includes a number pad and buttons for performing arithmetic operations.

  4. Error correction code - Wikipedia

    en.wikipedia.org/wiki/Error_correction_code

    Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

  5. 32-bit computing - Wikipedia

    en.wikipedia.org/wiki/32-bit_computing

    v. t. e. In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. [1] [2] Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle.

  6. 8-bit computing - Wikipedia

    en.wikipedia.org/wiki/8-bit_computing

    In computer architecture, 8-bit integers or other data units are those that are 8 bits wide (1 octet ). Also, 8-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers or data buses of that size. Memory addresses (and thus address buses) for 8-bit CPUs are generally larger than 8-bit ...

  8. Interdata 7/32 and 8/32 - Wikipedia

    en.wikipedia.org/wiki/Interdata_7/32_and_8/32

    Interdata 7/32 and 8/32. The Model 7/32 and Model 8/32 were 32-bit minicomputers introduced by Perkin-Elmer after they acquired Interdata, Inc., in 1973. Interdata computers are primarily remembered for being the first 32-bit minicomputers under $10,000. [1] [2] The 8/32 was a more powerful machine than the 7/32, with the notable feature of ...

  9. Mingw-w64 - Wikipedia

    en.wikipedia.org/wiki/Mingw-w64

    Mingw-w64 can generate 32-bit and 64-bit executables for x86 under the target names i686-w64-mingw32 and x86_64-w64-mingw32. History [ edit ] In 2005, Mingw-w64 was created by OneVision Software under cleanroom software engineering principles, since the original MinGW project was not prompt on updating its code base, including the inclusion of ...

    en.wikipedia.org/wiki/8-bit_color

    RGB color model. Web-safe color. v. t. e. 8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte ). The maximum number of colors that can be displayed at any one time is 256 per pixel or 2 8. [1]
