Understanding devices and drivers

As you know, the hardware and software are the two main components that constitute the personal computer (PC). The hardware represents the physical component of the PC, whereas the software constitutes the logical component of the PC. The hardware is a collection of physical devices, and the software is a collection of programmed instructions. Since the hardware and software are two components of a completely different nature, there is the need for an intermediate component to help establish communication between these components. That need encouraged device driver development. A device driver is a program that acts as a bridge between computer hardware and an operating system. It helps the operating system to recognize and control a certain device (that is, hardware) on the computer. Generally, device drivers are distributed through CD or...
