But, they use raster scanning too, updating the brightness of little tiny red, green and blue pixels many times a second.

但是，他们也使用光栅扫描，每秒多次更新微小的红色、绿色和蓝色像素的亮度。

To pull this off, computers needed an extra piece of hardware that could read characters out of RAM, and convert them into raster graphics to be drawn onto the screen.

为了实现这一点，计算机需要一个额外的硬件来从 RAM 中读取字符，并将它们转换成光栅图形以绘制到屏幕上。

If the graphics card saw the 8-bit code for the letter " K" , then it would raster scan the 2D pattern for the letter K onto the screen, in the appropriate position.

如果显卡看到字母“K”的 8 位代码，它就会将字母 K 的 2D 图案光栅扫描到屏幕上的适当位置。
