How to Memorize "hashing"

1. visualize
   

   - Imagine a large bucket with a pestle and mortar inside. The data is added to the bucket, and the pestle is used to grind it down into a smaller, fixed size. This is a simplified representation of how a hash function works.

2. associate
   

   - Associate the term 'hashing' with the idea of reducing data to a smaller, fixed size for easier handling and comparison.
   - Think of a hash function as a 'digital pestle and mortar' that grinds down data into a more manageable form.
