The process to control it is intriguing and interesting but the heart of the computer is simply this notion that we build our descriptions, our recipes, on a sequence of primitive instructions.
这个控制它的过程很耐人寻味,很有意思,但是计算机的核心仅仅只是,我们在初始指令序列上,建造描述、方法的一个概念罢了。
And the second thing we're going to need, is we're going to need a way to give instructions to the computer to manipulate that data.
我们需要的第二件事情是,我们需要一种,能给予计算机指令,以操作数据的方式。
Programming in this context boils down to telling the computer what to do.
在该环境下,编程是给计算机发出指令。
So in your mind, if you are now the computer program and you are executing this thing from top to bottom, what just has happened verbally is we are stepping into the line of code that says sort left half of elements.
在你们看来,如果你现在是计算机程序,正在从上到下执行一系列指令,刚才所发生的就是我们现在已执行到了这行代码,它告诉你要对左半部分的元素排序。
So on the left hand side of this particular languages environment I have some puzzle pieces and they are shaped and colored ; in a manner that hints out their functionality; any blocks that tell the Cat as we'll see in a moment, what to do something happen to be orange.
在这个程序语言界面的左手边有一些拼图,他们的形状和颜色代表他们的功能,我们马上就能看到;,任何一个给计算机发出指令的图块,都是橙色的。
Now this is a rain gauge, and it's sitting on a roof of a building, and when the water falls into this gauge, it sends a signal to the logic unit of the computer, which immediately notifies the memory bank of the computer to seek out its instructions for a rainy day.
这是一个雨量测量器,安装在一个楼房的,屋顶上,当水流入到这个测量器,它就给计算机的逻辑部件发送一个信号,计算机立即通知内存条,为下雨天找出相应的指令。
