hardware abstraction layer

A hardware abstraction layer (HAL) is a software component that acts as a bridge between a device's hardware and its operating system. It simplifies interactions by hiding the complex details of the hardware, enabling the OS and applications to communicate with hardware in a consistent way without needing to understand the specific hardware functions. This makes it easier to develop, update, and maintain software across different devices, as the HAL standardizes how hardware features are accessed regardless of hardware variations.
