He´s using the term VM, as a machine abstraction, wich C really is, in the same perspective the OS is a VM.. it will abstract you away, from device drivers, processor assembly, memory, (using files to represent a collection of data blocks in a block device) C is a VM. but not the same way the Java VM is a vm.. cause that is a VM on top of another VM (OS and processor assembly) its a software abstraction of a hardware system? its a VM.
