value types are stored in the memory.
reference types are stored in the heap.
all implicit datatypes,enums,structs are value types.
delegates,objects are reference types..

in the stack
when we delete a reference type pointer to the heap is
deleted from the stack

Answer / narayansahu
value types are stored on stack whereas reference types are
stored on heap memory.
dim i as integer
or
int i
i here ia a value type and will be stored on stack.
Actually nearly all the basic types are implemented as a
structure.
where as
dim i as new Point()
(assuming point as a class)
i here is a referece variable(pointer) and will be stored
on stack where as The Point object will be created on heap
and i will point to it.

Answer / thirupathi reddy
value refers what is present in the address of the memory
Reference type refers to the address of the memory
Ex:
int a = 10( here the value stores in the address 'a' and the value of that address is 10)
int b = &a (here the variable b refers the address of
the variable a)
here if we print("%d",a) the value prints
here if we print("%d",b) the reference value of a is printed.
this is the difference between "value" and "reference values"
