Windows Device Driver
Best Embedded System Training Institute in Bangalore | eTech Prowess
What is it?
A device driver is essentially a particular form of software application that is designed to
enable interaction with hardware devices. In the absence of the required device driver, the
corresponding hardware device fails to work.
A device driver typically communicates with the hardware by means of the communications
subsystem or computer bus to which the hardware is connected.
All device drivers are
operating system-specific and hardware-dependent. A device driver functions as a translator
between the hardware device and the programs or operating systems that use it. A device
driver sometimes may also be called a software driver.
What is the purpose of a device driver?
The sole purpose of a device driver is to instruct a computer on how to communicate with
the input/output device (I/O) by translating the operating system's I/O instructions into a
language that a device can understand. There are various types of device drivers for I/O
devices such as keyboards, mice, CD/DVD drives, controllers, printers, graphics cards and
ports.
Types of Drivers
There are device drivers for almost every device analogous with a computer. Device drivers
can be majorly classified into two categories, i.e., Kernel Device Drivers and User device
drivers.
Kernel device drivers are comprehensive device drivers that load with the operating system
into the memory as part of the operating system; not the entire driver but a pointer to that
effect so that the device driver can be implored as soon as it is required. The drivers have a
bearing on BIOS, motherboard, processor, and similar hardware form part of Kernel
Software.
While on the other hand, User Mode Device Drivers are the ones usually stimulated by
users during their session on a computer. Typically, drivers for most of the Plug and Play
devices fall into this category. User Device Drivers can be written to disk so that they don’t
act inflexible on the resources.
Further, device drivers are classified into the following types-
Generic and OEM Drivers
Sometimes, device drivers can be generic, or OEM related. Suppose the device driver comes
with the operating software, it most probably would be a generic device driver. Typically a
generic device driver is one that can be used with different brands of a particular device
type. For example, Windows 10 has a number of generic drivers that work without having to
install any other software manually.
Sporadically, the generic drivers don’t help. Hence, the original equipment manufacturers
create their own device drivers. These are OEM device drivers and have to be installed
separately after installing the operating system.
Virtual Device Drivers
Drivers which are used for virtual devices are called Virtual Device Drivers. Oftentimes, we
use some software to emulate hardware and the software used to run such virtual hardware
is a virtual device driver. For instance, if you are using a VPN, it may create a virtual network
card for connecting securely to the Internet while it is not a real physical card, but one set
up by VPN software. That card also needs a device driver, and the same VPN software will
install the virtual device drivers
Consequently, you can see there are different types of device drivers, and it is a tad bit
difficult to use just one or two categories to explain them. To recapitulate, the device driver
types were explained: kernel and user mode driver; generic and OEM device drivers, and
virtual device drivers.
So how do these drivers work exactly?
Let us be of the view that device drivers are like translators between a program we are using
and a device that program wants to utilize somehow and the software and the hardware
part were created by different people or companies and speak two completely different
languages, so a translator (the driver) allows them to communicate.
Simply put, a software program can provide information to a driver to explain what it wants
a piece of hardware to do, information the device driver understands and then can fulfill
with the hardware. Considering that there is a nearly endless supply of software and
hardware out there this is a pretty good deal.
