device driver

Author: 王欣 Date: 1996-01-12

        A small program that allows a computer to communicate with and control a device.
        Each operating system contains a standard set of device drivers for the keyboard,the monitor,and so on,but if you add specialized peripherals such as a CD-ROM disk drive,or a network interface card,you will probably have to add the appropriate device driver so that the operating system knows how to manage the device. In DOS,device drivers are loaded by the DEVICE or DEVICEHIGH commands in CONFIG.SYS
        设备驱动程序
        这是一个能使计算机连接并控制某一设备的小程序，每个操作系统中都包含有为键盘、显示器等设置的一套标准设备驱动程序，但是如果你要外加专门的外设，如光盘驱动器、或网卡，则可能需加入适当的设备驱动程序，以便让操作系统知道如何管理该设备，在DOS操作系统中，CONFIG.SYS文件中的DEVICE或DEVICEHIGH命令用以装载设备驱动程序。
