# 什么是驱动？

Devices are the physical “parts” of your computer. They may be external like printers and monitor or internal like graphics and audio cards.

为了能使用这些设备，需要知道如何跟它们沟通，这样的程序称作设备驱动。

When you attach a device to your computer, you must have the correct driver installed for that device to work. For example, if you plug in a printer but the correct driver is not available, you will not be able to use the printer. Normally, each model of device uses a driver that is not compatible with any other model.

在 Linxu 上，绝大多数设备默认就安装好驱动，因此一般都会正常工作。有些设备没有驱动，当然也就不能工作，您可能需要手动安装正确的驱动程序，或者有时正确的驱动仍然不能使用。

In addition, some existing drivers are incomplete or partially non-functional. For example, you might find that your printer cannot do double-sided printing, but is otherwise completely functional.
