Hardware Abstraction Layer (HAL) HAL, or hardware abstraction layer, is a thin layer of software at the base of the Microsoft Windows Server that offers a uniform interface between the underlying hardware and the higher layers of the operating system. The leaking abstraction is even lower! We’re Surrounded By Spying Machines: What Can We Do About It? Hardware abstraction is becoming much more common now in current operating systems than it was in the past. This library is not part of the Linux kernel, but rather belongs to the application layer on top of VHDL is used to describe a model for a digital hardware device.
