Our [mainframe computer] was installed with the maximum amount of solid-state RAM [random access memory] that could be addressed by the IOM [input/output module] and CPM [central processor module], and that was a massive 8 megabytes. This was a hard limitation as memory addresses were included in fixed length bit fields in the instructions and this limitation was architected into the machine design. 2, record 1, English, - fixed%2Dlength%20bit%20field

Security in cryptography comes from the fact that, even if the algorithm is publicly known, there are millions or trillions of possible "keys" that could have been used for encryption. For example, a bit-length of 56 bits makes possible roughly 72 quadrillion keys. 1, record 3, English, - bit%2Dlength%20of%2056%20bits

En cryptographie, la sécurité est liée au fait que, même si l'algorithme est connu de tous, il existe des millions, voire des trillions de «clés» possibles qui auraient pu servir au chiffrement. Par exemple, si la longueur est de 56 bits, il existe environ 72 quadrillions de clés possibles. 1, record 3, French, - longueur%20de%2056%20bits

All other things being equal, cryptographic strength is defined by the length of the cryptographic key (or "bit-length"), which establishes the number of possible permutations. With each bit added to the length of the key, the strength is doubled. 1, record 4, English, - bit%2Dlength

Toutes choses étant égales, la solidité du cryptogramme est proportionnelle à la longueur de la clé de chiffrement (ou la longueur en bits), qui détermine le nombre de permutations possibles. La solidité du cryptogramme double chaque fois que l'on ajoute un bit à la longueur de la clé. 1, record 4, French, - longueur%20en%20bits
