evership act ii reviewA hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used to index a hash … Visa mer A hash function is any function that can be used to map data of arbitrary size to fixed-size values, though there are some hash functions that support variable length output.
