Executable files

This question always confuses me :-

Suppose I write a program and compile it on a machine with operating system A and processor B

will the exe file run on a machine

with operating system A2 but processor B
operating system A but processor B2
operating system A2 and processor B2........

In a nutshell, Does the compatibility of a exe file depend on

only operating system ?

only machine architecture ?

or BOTH ?
