Answer #1

Dictionary will be used for storing the site addresses that are blocked by school authorities.

In Dictionary as like Map it is in the form of key-value pair. The key will be an immutable type.

If using Dictionary for the purpose of keeping the blocked site's addresses ,it will give a provision to mention whether it is a student or teacher or principal.Can use these profiles as keys and then the addresses can be values.

Mapping between key and value is possible in dictionary.Thus it is used in these kind of applications
