Why ORG?

If I write something like that:

_Pila SEGMENT STACK 'PILA'
ORG 0100h
DB 64 DUP('PILA ')
_Pila ENDS

_Datos SEGMENT PUBLIC 'DATOS'
ORG 0300h
CR EQU 0Dh
_Datos ENDS

_Codigo SEGMENT PUBLIC 'CODIGO'
ASSUME CS:_Codigo,DS:_Datos,SS:_Pila
ORG 034Fh

Why _Codigo begins at 034Fh, but _Datos & _Pila doesn't begin at 0300h and 0100h?

Ok, I saw. I am only talking about offset inside segments values that are allocated by the DEBUG program.

Is there any way to allocate my segments freely in the memory?

try something like:

MYSEG SEGMENT AT 0B800H

...
...
...

MYSEG ENDS

this is a kind of EXE program.
Exe can access more than 1 segment.
In your program _Datos & _Pila is actually set in (offset) 300h and 100h but it's in the different segment.
Take a look!
