What is the difference between String and StringBuilder?

 What is difference between String and StringBuilder?

String:-                                                    
          In simple word we can say that String is Immutable. We cannot insert, replace and append in String. When we replace value in String a new instance is created and new value is assigned to this new instance and old instance is deleted.
The Namespace for String is System.
Performance of String is low instead of StringBuilder.

StringBuilder:-
          It is mutable and we can insert, replace and append in StringBuilder. When we replace in StringBuilder append method is used. No new instance is created and no new value is assigned to StringBuilder.
The Namespace for StringBuilder is System.text
Performance of StringBuilder is High instead of String
