The Short Answer
Software developer here, There is a thing called a system call, and this is basically the program asking the operating system to perform some work, for example, reading data from a file. A program doesn't know how to do this, it's not part of its program to know what a hard drive is, or how different manufacturer hard drives work, or what a file system is – all that is abstracted away. Most operating systems offer a fairly standard complement of system calls, but there are minor variations and different conventions behind how they are called. The majority of the binary instructions in a program from one OS platform to the next will mostly be the same for a given hardware architecture, but program setup, tear down, and when the program has to reach outside itself for resources, these things are different between operating systems.
