  "term": "Concatenation",
  "field": "Cybersecurity",
  "definition": "1. The concatenation of bit strings A and B.\n\n2. As used in this Recommendation, the concatenation X || Y of bit string X followed by bit string Y is the ordered sequence of bits formed by appending Y to X in such a way that the leftmost (i.e., initial) bit of Y follows the rightmost (i.e., final) bit of X.\n\n3. The concatenation of two bit strings X and Y.\n\n4. The concatenation of bit strings X and Y.\n\n5. Concatenation; e.g. A || B is the concatenation of bit strings A and B.\n\n6. The concatenation of binary strings A and B.\n\n7. Concatenation\n\n8. Concatenation operation; for example, a || b means that string b is appended after string a.\n\n9. For strings X and Y, X || Y is the concatenation of X and Y. For example, 11001 || 010 = 11001010.\n\n10. Concatenation of two bit strings X and Y.\n\n11. Concatenation of two strings X and Y.\n\n12. Concatenation of two strings X and Y. X andYare either both bitstrings or both byte strings.",
