overloading means methods having the same name but with different parameters
overriding means methods having the same method name with same method signature that means having the same parameters also.
overloading means extension of the program.
overriding means replacement of the program

Let me add some thing .....

Overloaded methods
Which overloaded version of the method to call is based on the reference type of the argument passed at compile time.

Overriden methods
Which overriden version of the method to call is decided at runtime based on object type.

overloading is for same class while overriding is for child and parent class.
overloading will have same method name and different paramaeter but in overriding method name and parameter should be same.
