What Is Hash Computer Science

What Is Hash Computer Science. In a hash table, data is stored in an array format, where each data value has its own unique index value. Hashing functions are used for several applications in computer science, for example, cryptography and document fingerprinting.

Tabulation hashing, more generally known as zobrist hashing after albert zobrist, an american computer scientist, is a method for constructing universal families of hash functions by combining table lookup with xor operations. We have learned the objectives of hashing which include data integrity and authentication.

In Computer Science We Typically Encounter Two Applications Of Hash Functions.
