Overview#

Hardware Abstraction Layer (HAL) is is an abstraction layer (Application Programming Interface), implemented in software, between the physical hardware of a computer and the software that runs on that computer which allows hiding differences in hardware from most of the Operating System kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardware.
