To study a different star the astronomer moves his telescope. To study a different bacterium the biologist moves his microscope slide. In the case of the astronomer, it is the viewing instrument that is being moved, while in the case of the biologist it is the viewed object that is being moved. These scientists have no choice, the nature of their equipment requires that they operate in a pre-defined way. The user of a video display terminal (VDT), however, can be given a choice. The VDT user views a representation of an area of computer memory. In most cases the portion of memory the user wishes to examine is much larger than that which will fit on the screen at one time. For this reason almost all VDT's are equipped with some sort of "scroll function" that allows the user to display data that is located beyond the limits of the screen.
为了研究另一颗恒星,天文学家移动了他的望远镜。为了研究另一种细菌,生物学家移动了他的显微镜载玻片。在天文学家的情况下,正在移动的是观察仪器,而在生物学家的情况下,正在移动的是被观察物体。这些科学家别无选择,他们设备的性质要求他们以预定的方式运行。但是,可以给视频显示终端(VDT)的用户一个选择。 VDT用户查看计算机内存区域的表示。在大多数情况下,用户希望检查的内存部分远大于一次可显示在屏幕上的部分。因此,几乎所有的VDT都配备了某种“滚动功能”,使用户可以显示超出屏幕限制的数据。 P>
