What is a device driver and its types

What is a device driver? There is also a part of the computer that is always ignored. Yes, you read it right, here we are going to know about such an important part which is also called Computer Driver or Device Driver.

Do you know what is this computer driver and how does it work? If not then this article of today is going to be very interesting for you because today we will know about all those small big things related to computer driver which is very important.

When it comes to drivers, it does not mean the drivers that you see on the roads every day. A device driver is a program in your computer that controls a piece of hardware that is attached to your computer.

Almost everything in a computer requires a device driver so that they can function correctly. If a hardware piece does not have a driver, or does not have the correct driver, then that piece of hardware is completely useless for the remaining parts of the system.

It will be as if you have placed a child in a car and are asking him to drive that car. They have no idea about the car and its driving without any instruction. Device drivers do the same thing in your computer, they give a set of instructions to the computer how to use a device correctly.

A device driver is also called a computer driver, or hardware driver. It is a group of files. This helps in communicating different computer hardware with the operating system.

Without drivers, the computer can never send and receive data. As if sending data to the printer is done.

If an appropriate driver is not installed then the device will not function correctly either.

Computer driver type

Device drivers are basically small computer programs that allow operating systems to communicate with hardwares that are connected to a computer.

By the way, the types of device drivers are very different for different computer hardware. At the same time, according to the basic functionality of a computer, there are some selected drivers that must be present in all computers. Let's know about them.

BIOS

BIOS (basic input / output system), it is the most basic computer driver in existence and it is designed according to the first program which is booted when a PC is turned on.

This BIOS is stored in memory which is built into the motherboard and it is designed to boot the hardwares that are connected with PC, these include hard drives, video display output, keyboard And mouse.

Motherboard Drivers

Motherboard drivers are small programs that are read either by Windows or Linux and allow for basic computer functions within the operating system.

These drivers normally include programs that allow for broadband ports, USB ports and I / O ports, mouse and keyboard. According to the design of the motherboard, these drivers may also have some basic drivers for video and audio support.

BIOS are not at all the same as motherboard drivers.

Hardware Drivers

Hardware drivers are programs that are designed to allow pieces of computer hardware, such as expansion slots, to function in a computer.

Video cards, sound cards, network cards and other expansion cards come with driver discs to ease the installation process of the hardware. Other devices, such as some types of digital cameras and MP3 players, have PC drivers programmed with their software, which make them easy to use in personal computers.

Virtual Device Drivers

Virtual device drivers are very different from most drivers. Where in the majority of drivers, parts of hardwares are allowed to work with a particular operating system, while virtual device drivers emulate a piece of hardware and essentially trick the computer into thinking it read Is doing a piece of actual hardware only.
