  • 第2题：

    An 8-bit video card uses(72)bits to store information about each pixel, and thus can display 256 different colors.

    A．8

    B．16

    C．32

    D．1


    正确答案：A
    解析：本题用专业英语的形式考查了与视频卡相关的知识。随着计算机的不断发展，人们对图像效果要求的不断提高，视频卡也随着在进步，先后经历了8位、16位、32位再到更高位。如果是8位的视频卡，其能显示出图像的颜色为28，即共可表现256种颜色。参考译文：一个8位的视频卡使用8位去存储每个像素的信息，因此能显示256种不同的颜色。
