Introduction

In a previous episode of the Vectin engineering show, I talked about hash tables and how powerful and very commonly used they are. Given a key, we can find its corresponding value in no time, in zero seek time. It's a single axis in memory retrieving that value. Knowing the array position, the index, you can get the value of the array immediately because how does memory work? If you know the address of the RAM, where your cell exists, where your values exist,. In the CPU, you can fetch the value immediately for you.
