  2. Code-division multiple access - Wikipedia

    en.wikipedia.org/wiki/Code-division_multiple_access

    An example of orthogonal functions is shown in the adjacent picture. These vectors will be assigned to individual users and are called the code, chip code, or chipping code. In the interest of brevity, the rest of this example uses codes v with only two bits. Each user is associated with a different code, say v.

  3. QR code - Wikipedia

    en.wikipedia.org/wiki/QR_Code

    The HCC2D code specification is described in details in Querini et al. (2014), [92] while techniques for color classification of HCC2D code cells are described in detail in Querini and Italiano (2014), [93] which is an extended version of Querini and Italiano (2013). [94] Introducing colors into QR codes requires addressing additional issues.

  4. Cyclic redundancy check - Wikipedia

    en.wikipedia.org/wiki/Cyclic_redundancy_check

    The advantage of choosing a primitive polynomial as the generator for a CRC code is that the resulting code has maximal total block length in the sense that all 1-bit errors within that block length have different remainders (also called syndromes) and therefore, since the remainder is a linear function of the block, the code can detect all 2 ...

  5. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.

  6. Division (mathematics) - Wikipedia

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

    In abstract algebra, given a magma with binary operation ∗ (which could nominally be termed multiplication), left division of b by a (written a \ b) is typically defined as the solution x to the equation a ∗ x = b, if this exists and is unique. Similarly, right division of b by a (written b / a) is the solution y to the equation y ∗ a = b ...

  7. UTF-8 - Wikipedia

    en.wikipedia.org/wiki/UTF-8

    It may though require the user to change options from the normal settings, or may require a BOM (byte-order mark) as the first character to read the file. Examples of software supporting UTF-8 include Microsoft Word, [42] [43] [44] Microsoft Excel (2016 and later), [45] [46] Google Drive, LibreOffice and most databases.

  8. Division algorithm - Wikipedia

    en.wikipedia.org/wiki/Division_algorithm

    Long division is the standard algorithm used for pen-and-paper division of multi-digit numbers expressed in decimal notation. It shifts gradually from the left to the right end of the dividend, subtracting the largest possible multiple of the divisor (at the digit level) at each stage; the multiples then become the digits of the quotient, and the final difference is then the remainder.

  9. Java bytecode - Wikipedia

    en.wikipedia.org/wiki/Java_bytecode

    Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte, hence the name bytecode, making it a compact form of data.
