What Are Computer Drivers? Applications and Features

A computer driver is a collection of files that allows your computer’s operating system to communicate with different types of hardware, such as a graphics card, computer driver is a component of software that also instructs your device how to interact with the hardware.

What is a Computer Driver?

A computer driver is software that tells your device how to interact with the hardware like graphics cards, printers, keyboards, and monitors connected to it. They act as a link, ensuring the computer and the hardware understand each other to work smoothly. The role of drivers is important because they ensure the hardware works properly with your computer. Drivers are key in boosting the hardware’s performance and reliability, helping it to work at its peak.

Why do Computer Drivers need Updates?

Computer drivers act as a link between the hardware of your computer and its operating system. Updating drivers can lead to significant improvements in the performance of the hardware. For example, a graphics card driver update might include enhancements that increase the card’s speed and efficiency, leading to better video playback or more detailed and smoother graphics in games. Moreover, as technology evolves, new standards and protocols are developed. Driver updates ensure that the hardware stays up-to-date with these changes, maintaining its compatibility with newer technology. For instance, an update might allow a piece of hardware to work with the latest version of an operating system or ensure that it can communicate effectively with newer types of devices. Bugs and security issues are also reasons for driver updates. Sometimes, vulnerabilities are discovered that could potentially allow malicious actions or cause the hardware to malfunction. Updates can address these vulnerabilities, fixing the bugs and ensuring that the hardware remains secure and functions correctly.

How to Know if Computer Drivers Are Up to Date?

To see if your computer’s drivers are up to date, you can use the device manager, which shows all the hardware like graphics cards and printers. Right-click on any device listed there and choose to update the driver to find new updates. Your computer might also have a feature that checks for updates automatically, so make sure that’s active in your system settings. You can also go to the website of the hardware maker, where you can type in your device’s model and download the latest driver updates directly. This way, your computer stays in good shape, working well with the latest software and devices.

How do Computer Drivers Work?

Computer drivers often have a high level of privilege within the operating system (OS) runtime environment. Some device drivers, in reality, may be linked directly to the operating system kernel, a part of an operating system such as Windows, Linux, or macOS that remains in memory and executes all other code, including device drivers. Device drivers send requests for device access and actions from the operating system and its active programs to the hardware devices they support. They also transmit outputs or status messages from hardware devices to the operating system, and therefore to applications.

Types of Computer Drivers

• Device drivers: Device drivers are software that lets your computer work with different devices like printers or cameras. They translate your computer’s basic commands into specific actions the device understands. Each driver is made for a certain devices, ensuring it works right. They usually install automatically and get updates to fix bugs or improve how they work. Good drivers keep your computer stable and help devices run smoothly, while bad ones can cause problems or make devices stop working.
• Kernel drivers: Kernel drivers are core parts of a computer’s system that talk directly to the operating system and hardware. They manage important tasks like memory handling and device operations. Because they work so closely with the system’s core, they’re crucial for the computer’s stability and performance.
• User-mode drivers: User-mode drivers run in a separate space from the main operating system, which means they’re less likely to crash the whole computer if something goes wrong. They handle tasks related to specific user applications and are easier to manage and safer in terms of system stability.
• Virtual device drivers: Virtual device drivers create a fake, or virtual, device on your computer. They let software interact with this virtual device as if it were real hardware, useful for testing or running different systems within your main computer.
• Network drivers: Network drivers are software that helps your computer connect to the internet and other networked devices. They manage the communication between your computer and its network hardware, like Wi-Fi cards or Ethernet cables, making sure you can access the network and internet properly.
• Storage drivers: Storage drivers are the software that lets your computer talk to storage devices like hard drives, SSDs, and USB flash drives. They make sure your computer can read and write data to these devices, storing and accessing your files correctly.

Functions of Computer Drivers

• Enable communication: Drivers allow your computer’s operating system to talk to and control hardware devices, like printers and video cards.
• Manage devices: They give your computer the ability to use the hardware’s features, like sending a document to a printer or displaying images on a screen.
• Ensure compatibility: Drivers make sure that hardware works well with different versions of operating systems, helping devices to function correctly no matter the system they’re connected to.
• Boost performance: They are tailored to the specific needs of the hardware, helping devices to work at their best, often getting updates to improve how they function.
• Troubleshoot problems: When something goes wrong with a device, drivers help figure out the issue and can sometimes correct it.
• Organize resources: They manage how the hardware uses the computer’s memory and processing power, ensuring that devices don’t hog resources and slow everything down.

How can I Reinstall a Driver?

• Locate the search box in the lower corner of the Windows taskbar and type “Device Manager”
• Select Device Manager, and choose your device from the list provided. You may have more than one device to choose from in each category
• Right-click on the device you wish to update and select Uninstall
• Restart your computer using the Start menu; do not do a hard restart by pushing the power button
• Your computer will attempt to reinstall the driver upon restart.

Frequently Asked Questions on Computer Drivers – FAQs

What are drivers and their types?

Device drivers are broadly split into two categories; generic and specific. Generic device drivers are used for broad purposes such as keyboard control and mouse interaction. These are generally included as part of an operating system and can be used for basic functionality without any additional input from the user.

What are the drivers and examples?

A driver is software that lets a computer’s operating system communicate with hardware devices. Examples include a printer driver that allows your computer to print documents, and a graphics card driver that enables video and images to display on your screen.

How many drivers are there?

There are two basic types of Microsoft Windows drivers: User-mode drivers execute in user mode, and they typically provide an interface between a Win32 application and kernel-mode drivers or other operating system components. For example, in Windows Vista, all printer drivers execute in user mode.
