Hardware abstraction

Definition

Hardware abstraction refers to the process of creating a simplified interface that hides the complexities of the underlying hardware from software applications. This enables developers to write code that can run on different hardware architectures without needing to know the specific details of each one, promoting easier software development and maintenance. By using hardware abstraction, programs can achieve performance portability across various platforms, making them more flexible and efficient in utilizing resources.
