Explanation

Relative clause is a kind of dependent or subordinate clause that gives more information about a noun or subject in the same sentence. There are two types of relative clauses. First type is Defining Relative Clause and the other type is Non-Defining Relative Clause.  

Defining relative clause functions or identifies which person or thing you are talking about. If left out, the sentence would appear incomplete. However, Non-defining relative clause only describes and adds extra information about somebody or something.  If left out, the sentence would still make sense. A non-defining relative clause is usually put in commas.
