Bit manipulation is the act of algorithmically manipulating bits or other pieces of data shorter than a word. Programming tasks that require bit manipulation include low-level device control, error detection and correction algorithms, encryption algorithms, and optimization. For most other tasks, modern programming languages allow the programmer to work directly with abstractions instead of bits that represent those abstractions.

  • Bit manipulation is the act of algorithmically manipulating bits or other pieces of data shorter than a word. Programming tasks that require bit manipulation include low-level device control, error detection and correction algorithms, encryption algorithms, and optimization. For most other tasks, modern programming languages allow the programmer to work directly with abstractions instead of bits that represent those abstractions. Source code that does bit manipulation makes use of the bitwise operations: AND, OR, XOR, NOT, and bit shifts. Bit manipulation, in some cases, can obviate or reduce the need to loop over a data structure and can give many-fold speed ups, as bit manipulations are processed in parallel, but the code can become rather more difficult to write and maintain.
  • La manipulation de bit est l'action de manipuler algorithmiquement des bits ou toute forme de données inférieur à un octet. En informatique, la manipulation de bit est utilisée pour le contrôle bas niveau de périphériques, dans les algorithmes de détection et de correction d'erreur, de cryptage et pour l'optimisation. Pour la plupart des autres tâches, la plupart des langages de programmation moderne permettent au programmeur de travailler directement avec des abstractions plutôt qu'avec les bits qu'elles représentent. La manipulation de bit se fait à l'aide des opérations unaires: ET (AND), OU (OR), OU exclusif (XOR) et NON (NOT).
