common situation is an algorithm involving a lookup table: an implementation can include the entire table, which reduces computing time, but increases...

implement a lookup table with constant worst-case access time. A perfect hash function can, as any hash function, be used to implement hash tables, with the...

directly, by hand or using a calculator, or indirectly using a lookup table (or chart). The table displays BMI as a function of mass and height and may show...

though it is never used in queries or reports; it is done by creating a lookup table that contains the warehouse surrogate key and the originating key. This...

The Rijndael S-box is a substitution box (lookup table) used in the Rijndael cipher, on which the Advanced Encryption Standard (AES) cryptographic algorithm...

memory access will continue. The page table lookup may fail, triggering a page fault, for two reasons: The lookup may fail if there is no translation available...

maintain multiple tables, and each lookup must search through each table. Rainbow tables can achieve similar performance with tables that are k times larger...

operations, like traversing iterable data structures (e.g. strings, lookup tables, control tables and tree structures). In particular, it is often much cheaper...

arrays of addresses to functions as used in branch tables Indirect branch Lookup table an array of items to be matched, sometimes holding pre-calculated results...

A distributed hash table (DHT) is a distributed system that provides a lookup service similar to a hash table. Key–value pairs are stored in a DHT, and...
