  2. QR code - Wikipedia

    en.wikipedia.org/wiki/QR_code

    The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...

  3. Percent-encoding - Wikipedia

    en.wikipedia.org/wiki/Percent-encoding

    Percent-encoding. URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding, it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both ...

  4. Reed–Solomon error correction - Wikipedia

    en.wikipedia.org/wiki/Reed–Solomon_error...

    Being a code that achieves this optimal trade-off, the Reed–Solomon code belongs to the class of maximum distance separable codes. While the number of different polynomials of degree less than k and the number of different messages are both equal to , and thus every message can be uniquely mapped to such a polynomial, there are different ways ...

  5. Query string - Wikipedia

    en.wikipedia.org/wiki/Query_string

    Query string. A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.

  6. Uniform Resource Identifier - Wikipedia

    en.wikipedia.org/wiki/Uniform_Resource_Identifier

    Uniform Resource Identifier. A Uniform Resource Identifier ( URI ), formerly Universal Resource Identifier, is a unique sequence of characters that identifies an abstract or physical resource, [1] such as resources on a webpage, mail address, phone number, [2] books, real-world objects such as people and places, concepts. [3]

  7. QR decomposition - Wikipedia

    en.wikipedia.org/wiki/QR_decomposition

    QR decomposition. In linear algebra, a QR decomposition, also known as a QR factorization or QU factorization, is a decomposition of a matrix A into a product A = QR of an orthonormal matrix Q and an upper triangular matrix R. QR decomposition is often used to solve the linear least squares (LLS) problem and is the basis for a particular ...

  8. QR algorithm - Wikipedia

    en.wikipedia.org/wiki/QR_algorithm

    In numerical linear algebra, the QR algorithm or QR iteration is an eigenvalue algorithm: that is, a procedure to calculate the eigenvalues and eigenvectors of a matrix. The QR algorithm was developed in the late 1950s by John G. F. Francis and by Vera N. Kublanovskaya, working independently. [1] [2] [3] The basic idea is to perform a QR ...

  9. Link-local address - Wikipedia

    en.wikipedia.org/wiki/Link-local_address

    Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
