Hash
Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,
Hash table, also known as the hash table, is based on a fast access point of view design, but also a typical " space-time " approach. As the name implies, the data structure can be understood as a linear table, but the elements are not tightly
a hash table, also known as a hash table, is a data structure that is accessed directly from a key value. That is, it accesses records by mapping key code values to a location in the table to speed up lookups. This mapping function is called a hash

In the computational theory, there is no hash function, only one-way function is said. The so-called one-way function, is a complex definition, you can see the computational theory or cryptography data. The "Human" language describes the one-way
