Boxing is converting a value type to reference type
Unboxing is an explicit operation.
Eg.
In C# :
int X=1;
Object Y;
int Z;
Y=X; -------------> This is BOXING
Z=(int)Y; ----------------> This is UNBOXING

Boxing is a process of converting value type into reference type while unboxing is vice versa
What happened in backend.
Value type is stored in Stacks
Reference type is stored in Heap
So boxing.
Values shifted Stacks to Heap and vice versa.

Boxing permits any value type to be implicitly converted to type object or to any interface type implemented by value type.
Unboxing is vice verse of boxing operation where the value is copied from the instance into appropriate storage location.
EX:-
Dim X As Integer
Dim Y As Object
X=10<--BOXING PROCESS-->
Y=X<--UNBOXING PROCESS-->
