Nothing else is the best and most suitable.

Next drive first, then install.

Yours first talk about what system yours is.

It is a program that allows high-level computer software to interact with hardware.

This program creates a hardware-to-hardware, or hardware-to-software interface, which is connected to the hardware via a bus or other communication subsystem on the motherboard, which makes it possible to exchange data on the hardware device.

Depending on the computer architecture and operating system platform, the driver can be 8-bit (8-bit bit (16-bit bit (32-bit (64-bit), which is to reconcile the dependencies between the operating system and the driver, for example, in the era of the 16-bit operating system of Windows, most of the drivers are 16-bit.

For 32-bit Windows XP, 32-bit drivers are used (Microsoft provides Windows Driver Model to implement drivers), while 64-bit Linux or Windows platforms must use 64-bit drivers (both WDM and WDF can implement 64-bit drivers).

A driver, which stands for Device Driver, is a special program added to the operating system that contains information about the hardware device. This information enables the computer to communicate with the appropriate device.

A driver is a configuration file written by a hardware manufacturer based on the operating system, and it can be said that without the driver, the hardware in the computer cannot work. Different operating systems have different hardware drivers, and various hardware manufacturers will continue to upgrade drivers in order to ensure hardware compatibility and enhance hardware functions. Such as:

On average, NVIDIA graphics chip companies upgrade their graphics drivers2 3 times a month. Drivers are part of the hardware, and they are an indispensable and important component when you install new hardware. Whenever you install a hardware device that is not originally part of your computer, you will be asked to install a driver to connect the new hardware to your computer's system.

The driver plays the role of communication, telling the computer system what the hardware is capable of, and also communicating the system's instructions to the hardware to get it to work. When you're installing new hardware, you're always asked to put in "drivers for this hardware", and a lot of people start to have a headache. You either can't find the driver's platter, you can't find the location of the file, or you don't know what the driver is.

For example, installing hardware peripherals such as printers is not complete by connecting the cables, and if you start using them at this time, the system will tell you that you can't find the driver. What to do? Referring to the manual may not be able to install it smoothly.

In fact, there are still certain conventions and general rules to be found in terms of installation, which can help you achieve barrier-free installation.

What is Drive?

Although the driver is constantly serving you after you turn on the computer and enter the system, it is not as accessible as the computer hardware, nor is it as clear as the operating system, nor is it as eye-catching as the game or multi-** application, it is just doing what it should do in the background in obscurity, so it is always ignored by many friends.

So what is the drive? Simply put, the driver is used to provide an interface to the operating system to access and use the hardware device, and realize the communication program between the operating system and all the hardware devices in the system, which can tell the system the functions contained in the hardware device, and when the software system wants to achieve a certain function, mobilize the hardware and make the hardware complete it in the most efficient way.

Speaking of the image, the driver is the "herald" between the software and the hardware, this link is very important, once there is a problem, then the software requirements will be no one to respond, and the hardware has no strength but can not play, in that situation friends will find that their original powerful and colorful computer is like a puddle of stagnant water, nothing can be done. Therefore, it is not an exaggeration to say that the driver is the soul of hardware.

A computer is composed of a lot of hardware, and these hardware have their own corresponding drivers, only when the drivers are installed, the hardware can play its most advantage. A driver is software that makes good use of the hardware performance. Motivation and source.

The driver is the guarantee for the maximum performance and stable operation of the hardware.

The drive acts like a lubricant.

It can make the performance of the hardware better.

At the same time, it also improves the compatibility and coordination with other hardware and software.

A driver is a program that lets the computer know the device you have installed and makes the device work properly on your computer.

The driver can be regarded as a translation, the operating system cannot communicate directly with the hardware, the operating system calls the functions provided by the driver, the driver encapsulates the process of operating the hardware, and the driver is the middleman.

Programs that are directly geared towards hardware.

To put it simply, it is to tell your CPU how to use your computer's hardware. So if you don't have a driver, the hardware won't work.

Some of the applications on your computer are drivers.

Generally, economical cars are front-wheel drive, because the cost is low. But since all the things of the car's drive mechanism and steering mechanism are placed in front of the car, the engine cannot be very large, which limits the displacement of the engine.

Generally, high-end cars (such as Mercedes-Benz, BMW, and Audi) will choose front-rear-wheel drive or four-wheel drive, so that the engine may increase displacement. After the displacement is large, the speed is higher, the comfort is also higher, and the cost is also higher.

Everyday cars don't have much horsepower, so it's enough to use front-wheel drive. Imported off-road vehicles are generally four-wheel drive, and domestic off-road vehicles have also launched two-wheel drive versions for low cost.
