Hashing in a nutshell: apply hash function f() to the keys, bucket the data records accordingly. Where a radix sort would use part of the key directly (like a hash function that just masks bits), hashing picks a more complicated function. So there's a tradeoff. Your data is no longer sorted by the key, but by f(key). On the other hand, you get a flat distribution that makes the bucketing work.

Can you truly not see the similarity between distribution sort and hashing?
