Abstraction is the act of representing essential features without including the background details or explanations. In the computer science and software engineering domain, the abstraction principle is used to reduce complexity and allow efficient design and implementation of complex software systems.
1 in computers a hardware abstraction layer hal is a layer of programming that allows a computer operating system to interact with a hardware device at a general or abstract level rather than at a detailed hardware levelwindows 2000 is one of several operating systems that include a hardware abstraction layerthe hardware abstraction layer can be called from either the operating system s kernel or from a device driver in either case the calling program can interact with the device in a more general way than it would otherwiseindows 2000 is one of several operating systems that include a hardware abstraction layer the hardware abstraction layer can be called from either the operating system s kernel or from a device driver in either case the calling program can interact with the device in a more general way than it would otherwise
