A software driver is a piece of code that enables an operating system to communicate with hardware devices. The operating system makes use of this code to communicate with a given hardware component and perform functions for the user that are appropriate to the device that is being used.
A variety of different kinds of hardware can be connected to computers each one of which requires its own unique software driver to function correctly. This hardware can include external peripherals like keyboards and mice, as in addition to internal components such as a CPU and data ports.
The vast majority of drivers are downloaded from the companies that developed and built the hardware. These companies offer software applications that scan the web for updates available to their device driver. The program will either inform the user that an update is available or allow them to manually download and then install the latest version compatible with their device.
It is important to remember that the most efficient and simplest method to determine if the device driver is outdated is to look up the site of the manufacturer. These companies are typically well-informed about the way their hardware functions and typically offer plenty of assistance and suggestions on the use of their products. These companies will often include a small utility application with their hardware. This software can be used to check for updates and compatibility issues, and then automatically download and update any compatible new releases.
