WebAug 3, 2024 · Difference between Static and Dynamic Hashing. Hashing is a computation technique in which hashing functions take variable-length data as input and issue a shortened fixed-length data as output. The output data is often called a "Hash Code", "Key", or simply "Hash". The data on which hashing works is called a "Data Bucket". http://user.it.uu.se/~kostis/Teaching/DM-05/Slides/association2.pdf
