Device Driver in computing refers to a special kind of software program or a specific type of software application that controls a specific hardware device that enables different hardware devices to communicate with the computer’s Operating System. A device driver communicates with the computer hardware by computer subsystem or computer bus connected to the hardware. Show
Device Drivers are essential for a computer system to work properly because without a device driver the particular hardware fails to work accordingly, which means it fails in doing the function/action it was created to do. Most use the term Driver, but some may say Hardware Driver, which also refers to the Device Driver.  Working of Device Driver: Device Drivers depend upon the Operating System’s instruction to access the device and perform any particular action. After the action, they also show their reactions by delivering output or status/message from the hardware device to the Operating system. For example, a printer driver tells the printer in which format to print after getting instruction from OS, similarly, A sound card driver is there due to which 1’s and 0’s data of the MP3 file is converted to audio signals and you enjoy the music. Card reader, controller, modem, network card, sound card, printer, video card, USB devices, RAM, Speakers, etc need Device Drivers to operate. The following figure illustrates the interaction between the user, OS, Device driver, and the devices: Types of Device Driver: For almost every device associated with the computer system there exist a Device Driver for the particular hardware. But it can be broadly classified into two types i.e.,
Virtual Device Driver: There are also virtual device drivers(VxD), which manage the virtual device. Sometimes we use the same hardware virtually at that time virtual driver controls/manages the data flow from the different applications used by different users to the same hardware. It is essential for a computer to have the required device drivers for all its parts to keep the system running efficiently. Many device drivers are provided by manufacturers from the beginning and also we can later include any required device driver for our system. Updated: 10/11/2021 by More commonly known as a driver, a device driver or hardware driver is a group of files that enable one or more hardware devices to communicate with the computer's operating system. Without drivers, the computer could not send and receive data correctly to hardware devices, such as a printer. What devices need drivers?Hardware devices that are unknown by the operating system or have features unknown by the operating system all require drivers. Below is a list of hardware devices and peripherals that require drivers.
What devices may not need driversToday's operating systems have many generic drivers that allow hardware to work at a basic level without needing drivers or software. However, if that device has features unknown to the operating system, it will not work without drivers. For example, you could plug any keyboard into a computer and expect it to work. However, if that keyboard has any special keys or features, they will not work until the drivers are installed.
Note The operating systems' generic driver may not be updated as often as the drivers from a hardware manufacturer or computer manufacturer. What happens if a driver is not installed?If the appropriate driver is not installed, the device may not function properly, if at all. With some devices, the device may work, but all of its features may not work. For example, a computer mouse usually works without drivers, but if it has more buttons than the traditional mouse, those extra buttons will not work until the drivers are installed. For Microsoft Windows users, missing drivers may cause a driver conflict or an error in the Device Manager. If problems or conflicts are encountered with drivers, the computer manufacturer or hardware manufacturer releases a driver update to fix the problems. If updated drivers are available, those drivers need to be installed to replace the existing driver code. Can a driver make my computer do more?Installing a driver only makes the hardware installed in the computer function properly. If the correct driver is not installed, installing the latest driver for the hardware can take full advantage of the device. However, you cannot install a driver for hardware not installed in the computer and expect it to make your computer faster or more capable. In other words, installing video card drivers for a video card that's not installed in the computer does not give your computer all the capabilities of that video card. In this example, you'd need the video card hardware and the video card drivers to be installed. Are computer drivers free?Almost all computer and hardware manufacturers provide free drivers, updates, and software for their devices. You can find a list of direct links to all company's pages through our computer driver page. However, companies no longer in business or products that are no longer supported may no longer offer free drivers. In this situation, third-party companies may host and offer drivers but charge for them. Are computer drivers safe?As long the driver you're downloading comes from a reputable source, like the manufacturer of the device, it is considered safe. If you have to download a driver from a third party, it's difficult to know if they've modified the driver code. Unfortunately, like any computer software, drivers can also be infected with viruses and other malware. We recommend having an antivirus installed and running on a computer before you download and install a driver from a third party. What if I download the wrong driver?If you mistakenly download the wrong driver and attempt to install it on your computer, it will fail during the install. However, it's possible to install a driver for a device that does not exist. However, even if this is done, you'd only get errors about the device not being detected or see problems with the non-existent device in Device Manager. Installing the wrong driver on a computer that's working would not cause it to stop working. However, if you removed a working device and then installed the wrong drivers, that may cause problems.
