Answer 5

Well, you can think of it like a real life dictionary. A dictionary item contains of a pair of key and value. In real life dictionary, let's assume an English ~ German dictionary, the keys are words in English, and the values are the respective translation in German.

In real life dictionary we search a word by looking at the markers (marked with letters usually). In programming, the technique is so called "hashing", a way to convert the key to a form that can be searched quickly (technical details are far beyond my league).

A dictionary's item key is unique, but an item's value may not be. That means if you add a new item having a key whose value can be translated equal to an existing item, the existing item value will be overwritten by the new value, but the key remains.

I hope you now get a rough idea of it. If you have another doubt more specific to dictionary, you are welcome to ask.
