Moving up another layer of abstraction.

向上移动另一层抽象。

With billions of transistors in just your smartphones, computers can seem pretty complicated, but really, they're just simple machines that perform complex actions through many layers of abstraction.

如果只看你手机中那数十亿晶体管的话，计算机可能看起来会相当复杂，但是讲真，它们只是通过许多层的抽象结构表现复杂行为的简单机器。

Ok, now that we've got NOT, AND, and OR gates, and we can leave behind the constituent transistors and move up a layer of abstraction.

好的， 既然我们已经有了 NOT、AND 和 OR 门，我们就可以抛开组成晶体管并向上移动一个抽象层。

Like many things in computing, the fundamental operation is relatively simple.. it’s the layers and layers of abstraction that’s mind blowing -- like a russian doll that keeps getting smaller and smaller and smaller.

就像计算中的许多事情一样，基本操作相对简单。令人兴奋的是层层抽象——就像一个越来越小的俄罗斯套娃。
