Basically, the operation code tells the ALU what operation to perform.

基本上，操作码告诉算术辑单元执行什么操作。

Over the course of this series, we're going to go from bits, bytes, transistors and logic gates, all the way to Operating Systems, Virtual Reality and Robots!

在这个系列中，我们会了解bits，bytes，晶辑门一直到操作系统，虚拟现实机器人！

The third stage is the concrete operational stage, and this is when a child becomes capable of performing logical operations, but only in the presence of actual concrete objects.

第三阶段是运算阶段，此时儿童能够进行辑操作，但仅限于实际存在的在场的情况下。

Just as a logical process, as a practice, I can't pick it apart in the way that we were just talking about a moment ago about thousands of drones being like sent up in very tricky manners, right?

作为一个辑过程和实践操作，我无法像刚才讨论的那样， 将数千架无人机以极其复杂的方式升空的情况拆解开来，对吧？

Thus although a valid inference from the-letters to their meaning is possible, and could be performed by the reader, it is not in fact performed, since he does not in fact perform any operation which can be called logical inference.

因此，尽从字母到它们的含义的有效推理是可能的，并且可以由读者执行，但实际上并没有执行，因为他实际上没有执行任何可以称为辑推理的操作。
