device drivers Windows Device DriverBest Embedded System Training Institute in Bangalore | eTech ProwessWhat is it?A device driver is essentially a particular form of software application that is designed toenable interaction with hardware devices. In the absence of the required device driver, thecorresponding hardware device fails to work.A device driver typically communicates with the hardware by means of the communicationssubsystem or computer bus to which the hardware is connected. All device drivers areoperating system-specific and hardware-dependent. A device driver functions as a translatorbetween the hardware device and the programs or operating systems that use it. A devicedriver 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 withthe input/output device (I/O) by translating the operating system's I/O instructions into alanguage that a device can understand. There are various types of device drivers for I/Odevices such as keyboards, mice, CD/DVD drives, controllers, printers, graphics cards andports.Types of DriversThere are device drivers for almost every device analogous with a computer. Device driverscan be majorly classified into two categories, i.e., Kernel Device Drivers and User devicedrivers.Kernel device drivers are comprehensive device drivers that load with the operating systeminto the memory as part of the operating system; not the entire driver but a pointer to thateffect so that the device driver can be implored as soon as it is required. The drivers have abearing on BIOS, motherboard, processor, and similar hardware form part of KernelSoftware.While on the other hand, User Mode Device Drivers are the ones usually stimulated byusers during their session on a computer. Typically, drivers for most of the Plug and Playdevices fall into this category. User Device Drivers can be written to disk so that they don’tact inflexible on the resources.Further, device drivers are classified into the following types-Generic and OEM DriversSometimes, device drivers can be generic, or OEM related. Suppose the device driver comeswith the operating software, it most probably would be a generic device driver. Typically ageneric device driver is one that can be used with different brands of a particular devicetype. For example, Windows 10 has a number of generic drivers that work without having toinstall any other software manually.Sporadically, the generic drivers don’t help. Hence, the original equipment manufacturerscreate their own device drivers. These are OEM device drivers and have to be installedseparately after installing the operating system.Virtual Device DriversDrivers which are used for virtual devices are called Virtual Device Drivers. Oftentimes, weuse some software to emulate hardware and the software used to run such virtual hardwareis a virtual device driver. For instance, if you are using a VPN, it may create a virtual networkcard for connecting securely to the Internet while it is not a real physical card, but one setup by VPN software. That card also needs a device driver, and the same VPN software willinstall the virtual device driversConsequently, you can see there are different types of device drivers, and it is a tad bitdifficult to use just one or two categories to explain them. To recapitulate, the device drivertypes were explained: kernel and user mode driver; generic and OEM device drivers, andvirtual 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 usingand a device that program wants to utilize somehow and the software and the hardwarepart were created by different people or companies and speak two completely differentlanguages, so a translator (the driver) allows them to communicate.Simply put, a software program can provide information to a driver to explain what it wantsa piece of hardware to do, information the device driver understands and then can fulfillwith the hardware. Considering that there is a nearly endless supply of software andhardware out there this is a pretty good deal.Why choose us?eTech Prowess, the Best Embedded System training institute in Bangalore offers a 16-WeeksWindows device driver job oriented course in bangalore to cater to the specificrequirements of the clients.
