You put your horizontal " X" coordinate here, vertical " Y" coordinate here.

你把横坐标" X" 值输在这里纵坐标" Y" 值输入这里。

But it wasn't too restrictive -- you could still put any value, any formula, in any cell.

Behind the scenes, this operating system uses buffers for storing the text values that are entered.

在幕后，该操作系统使用缓冲区来存储输入的文本值。

They look something like this: Now, let's put in some real values.

它们看起来像这样： 现在，让我们输入一些实际值。

We can write out a little logic table that shows the original value under Input, and the outcome after applying the operation under Output.

我们可一个小逻辑表，在输入下显示原始值，在输下显示应用操作后的结果。

So it takes some time for the input values to travel through all these things to the output value until the signal is stable on the output.

因此，输入值需要一些时间才能通过所有这些东西到达输值，直到信号在输端稳定为止。
