Microsoft has attempted to reduce system instability due to poorly written device drivers by creating a new framework for driver development, called Windows Driver Frameworks (WDF).
Although this information can instead be learned by reverse engineering, this is much more difficult with hardware than it is with software. In such cases, it is important that the hardware manufacturer provide information on how the device communicates. However, in recent years, non-vendors have written numerous device drivers for proprietary devices, mainly for use with free and open source operating systems. Typically, the Logical Device Driver (LDD) is written by the operating system vendor, while the Physical Device Driver (PDD) is implemented by the device vendor. Moreover, it was traditionally considered in the hardware manufacturer's interest to guarantee that their clients can use their hardware in an optimum way. This is because they have better information than most outsiders about the design of their hardware.

The task of writing drivers thus usually falls to software engineers or computer engineers who work for hardware-development companies. These factors make it more difficult and dangerous to diagnose problems. Even drivers executing in user mode can crash a system if the device is erroneously programmed. In contrast, most user-level software on modern operating systems can be stopped without greatly affecting the rest of the system. Because drivers require low-level access to hardware functions in order to operate, drivers typically operate in a highly privileged environment and can cause system operational issues if something goes wrong. Writing a device driver requires an in-depth understanding of how the hardware and the software works for a given platform function.

The commands needed to control a 16550 UART are much different from the commands needed to control an FTDI serial port converter, but each hardware-specific device driver abstracts these details into the same (or similar) software interface. At a lower level, a device driver implementing these functions would communicate to the particular serial port controller installed on a user's computer.
Programmers can write higher-level application code independently of whatever specific hardware the end-user is using.įor example, a high-level application for interacting with a serial port may simply have two functions for "send data" and "receive data". The driver software also relays information back to the computer, so the user can be aware of ink levels, hardware errors, etc.The main purpose of device drivers is to provide abstraction by acting as a translator between a hardware device and the applications or operating systems that use it. It also gives the printer all of the details about the how the document is supposed to be printed, like the colors, paper size, and more. When the "print" button is pressed for the purpose of printing a document, for example, the printer's driver will translate the document into a language the printer can understand. For example, a computer printer needs to be "told" what to do by the computer it is connected to. Driver updates are made available to users through a variety of means, and are available for most computer device drivers.ĭriver updates are downloaded from a manufacturer's website.Ī driver is a computer program that allows a computer system to communicate with a particular hardware component.
What is a driver update update#
Some types of drivers may need constant updates, while others may never need an update at all. Driver updates are computer software updates that are designed to make corrections or add enhancements to existing drivers.
