Boxing is the process of converting value type to reference
type.

Unboxing is the process of converting from a reference type
to a value type.

Both are slow and should be avoided when possible or
unneeded.

Dim st AS String
Dim obj As Object
Dim n As Integer = 5
st = n ' Boxing happens
obj = n ' Boxing happens

n = st ' Unboxing happens
n = obj ' Unboxing happens
