电脑的显示系统包括两个部件:显示器和显示卡(也叫适配卡)。显示卡的基本作用是控制电脑的图形输出,它在CPU和显示器间起着“中间人”的作用。通常显示卡是以附加卡的形式安装在电脑主板的扩展槽中,或是集成在主板上的。 The computer’s display system consists of two components: a display and a graphics card (also called an adapter card). The basic function of a graphics card is to control the computer’s graphics output, which acts as a “middleman” between the CPU and the monitor. Usually graphics cards are installed in the form of additional cards in the computer motherboard expansion slot, or integrated in the motherboard.
