The AND Boolean operation takes two inputs, but still has a single output.

AND 布尔运算需要两个输入，但仍然只有一个输出。

For example, another useful boolean operation in computation is called an Exclusive OR - or XOR for short.

例如，计算中另一个有用的布尔运算称为异或 - 或简称 XOR。

The last boolean operation is OR -- where only one input has to be true for the output to be true.

最后一个布尔运算是 OR —— 只有一个输入必须为真，输出才为真。
