The HAL (hardware abstraction layer) is the layer between the OS and the hardware
The purpose of a driver on any computer (not just Dell brand computers) is to serve as a communicator between your computer's operating system and computer hardware. For example, when you install a printer (hardware) the driver helps you to inform your operating system that the printer is there so it can be used.

the HAL
Operating systems software manages the hardware on your computer, and provides an interface between the user- or application software, and the computer hardware.
An operating system (OS) is software, consisting of programs and data, that runs on computers, manages computer hardware resources, & provides common services for execution of various application software. For hardware functions such as input & output and memory allocation, the operating system acts as an intermediary between application programs & the computer hardware. Operating systems are found on almost any device that contains a computer from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems for personal computers are: Mac OS X, Microsoft Windows & Linux.
