A driver is a software component that lets the operating system and a device communicate. For example, when an app needs to read data from a device, it calls a function implemented by the operating system. The operating system then calls a function implemented by the driver. The driver, usually developed by the device's manufacturer, knows how to c...
Our explanation simplifies the concept of drivers. Here are some more points to consider:
•Drivers don't always have to be developed by the device's manufacturer. If a device follows a published hardware standard, Microsoft can write the driver, so the device designer doesn't have to provide one.
•Not all drivers communicate directly with a device. Often, several drivers layered in a driver stack take part in an I/O request. The conventional way to visualize the stack is with the first participant at the top and the last participant at the bottom, as shown in this diagram. Some drivers in the stack change the request from one format to another. These drivers don't communicate directly with the device. Instead, they change the request and pass it to drivers that are lower in the stack.
Function driver: The driver that communicates directly with the device is called the function driver.
Filter driver: Drivers that do auxiliary processing are called filter drivers.

Below is a simple breakdown of what unfolds when a hardware device connects to a computer through a device driver: When you decide to use a hardware device, such as a keyboard, a request is sent from your computer's operating system and applications in operation to the device driver.
