What are Device Drivers?
Driver in English:
A device driver is a software that allows your computer to communicate with hardware or devices. The device driver operates or controls a device attached to the computer. Without drivers, any hardware connected to your computers such as a video card or printer will not work properly.
When you buy a branded PC or laptop, there are many device drivers in-built in this product. But when you buy a chord device later, you have to install the driver for this device.
Typically, device drivers communicate with a hardware bus or communication subsystem from a hardware-connected device. It sends commands to the device from application software or operating system or receives data from this device.
Why is a device driver required?

Computers and their operating systems are not able to know how to control every device. This is why every device comes with its own driver. The operating system "calls" the driver and the driver "drives" the device.
When a new hardware device is connected to a computer, such as a CD-ROM drive, printer or sound card, it is necessary to install the driver to make it work properly. If the peripheral device changes, its driver must also be changed. The device drivers depending on your operating system are also 8-bit, 16-bit, 32-bit, and 64-bit. New versions of these drivers are written and released by the manufacturer of the device.
What is a peripheral device?
Peripheral devices are devices that are connected to a computer. They are not part of the computer system (motherboard, processor) but are necessary to increase the functionality of the computer.
Device Driver Explanation:
A device driver is basically a translator. Its inputs are high-level, and its outputs are low-level, hardware-specific instructions used by hardware controllers and interfacing the input-output devices to the operating system.
