程度副詞

That between the mouse click and the video playing,

there was something that captured your intention,

在這之間有樣東西，得知你的意圖

and inject ourselves into a click of a mouse.

you'd see that it's really a very simple machine.

and a system for detecting motion and distance.

that makes these measurements with lights and sensors,

透過光及感應器來完成這些計算

but older ones did this with a hard rubber ball

舊一點的滑鼠有一顆硬硬的橡膠球

it's handled by the basic input/output subsystem.

This subsystem acts like the eyes and ears

Basically, it provides a way for the computer

基本上，這個系統提供電腦一個方法

to keep the CPU from being overwhelmed by distractions.

that your mouse click is pretty important

「嘿，CPU！這東西被點選了。」

Just like your brain doesn't take up your whole body,

the CPU doesn't take up the whole computer,

instructions to move your mouse around on the screen,

to run that clock widget on your desktop,

manage the files you're editing on the hard drive,

處理在硬碟中，你在編輯的檔案

Your computer's CPU is one heck of a multitasker!

CPU就是個超神的多重任務處理王

Let's drop everything now and deal with that!"

先停止所有任務，然後處理那個！」

and for dealing with letters sent by the keyboard.

Each program was initially written by a human

in a human-readable programming language,

But human programs take up a lot of space

但是人類的程式占據了很多空間

and contain a lot of unnecessary information to a computer,

and stored in bits of ones and zeros in memory.

The CPU realizes that it needs instructions

so it looks up the address for the mouse program

and sends a request to the memory subsystem

Each instruction in the mouse device driver

And that's not nearly the end of the story!

Because the CPU learns that the mouse was clicked

and so, the CPU asks memory for the monitor program

CPU會要求記憶體提供顯示器的程式

to show the video associated with the button,

And let's just say there are a lot of programs involved

before you even see the button on the screen

So, just the simple task of clicking your mouse

means visiting all of the critical components
