Chrome OS和Android的三大不同点By Steven J. Vaughan-Nichols | December 5, 2010, 8:15pm PST发表于：2010-12-5
On December 7th, Google is expected to announce the release of a laptop with the first version of the Chrome operating system. Concurrently, Google is going great guns with Android. Does Google really need two operating systems? So what’s going on here?12月7日，谷歌有望宣布一个载有第一版Chrome操作系统的便携电脑发行。与此同时，Google正带着Android大力前行。Google真的需要两个操作系统吗？这里发生着什么？
Here’s what Google is up to. Yes, both Android and Chrome OS are Linux-based operating systems. Neither, at the application level, uses the common Linux desktop application programming interfaces (API) that are used by the GNOME or KDE desktops and their applications.以下便是Google的现状。是的，Android和Chrome OS都是基于Linux的操作系统。并且，在应用层，都没使用为GNOME或KDE桌面以及它们的应用所采用了的流行的Linux桌面应用编程接口（API）。
They’re also similar in that both use a common set of techniques to make them more secure. The most important of these is process sand-boxing. What this means is that any Chrome or Android application has just enough access to the system to do its job.他们还都使用着同一个使之更为安全的技术。其中最重要的一个环节是沙盒技术。沙盒技术这里指，任何Chrome或Android应用都只能拥有刚刚好能完成其本职工作的系统访问权限。
Once you’re past this, the two look and act in very different ways. Here are their main points of difference:以上这些都撇开之后，二者的外形和行为方式就很不相同了。以下是它们主要的差异点：
1) Android is for Phones & Tablets; Chrome OS is for Netbooks1) Android是用于手机和平板电脑的；Chrome OS是用于上网本的
Google said at the start that “Google Chrome OS is being created for people who spend most of their time on the Web, and is being designed to power computers ranging from small netbooks to full-size desktop systems.” Google hasn’t always been on message with this.Google一开始就说，“Google Chrome OS是创造给把他们大部分时间花在网上的人们，并被设计用来驱动从小小上网本直到完整桌面系统之间所有类型的计算机的。”Google对此再没有过过多的信息。
Google also took its time getting even a Chrome beta out the door. Now that Chrome OS is about to be unveiled, we know that it is going to be Google’s “desktop” operating system, while Android is for smart phones and tablets.Google在放出其Chrome测试版时也是从容不迫的。现在Chrome OS要揭晓了，我们便知Google“桌面”操作系统将要问世了；而Android只是给智能手机和平板电脑用的。
The Android interface is designed foremost for touch. Google Chrome OS looks and acts just like the Chrome Web browser.Android界面主要是为触摸屏而设计的。Google Chrome OS外形和行为就像Chrome Web浏览器一样。
2) Chrome OS won’t run Linux desktop or Android Apps2) Chrome OS运行不了Linux桌面或Android的应用
I use quotes around “desktop” with good reason. While Chrome OS will be used like a desktop operating system, it’s not a traditional fat-client desktop like Windows or even a Linux desktop such as Mint. Instead, all of its “applications” will be cloud-based. To see what I mean, just look at the Chrome browser and Google Apps. You’re looking at a sketch of the Google Chrome OS.我给“桌面”一词加引号，是有充足理由的。虽然Chrome OS会像一个桌面操作系统一样被使用，但它不是一个传统的胖客户端桌面，像Windows，或像Mint等Linux桌面。相反，它所有的“应用程序”都将是基于云的。要理解我所说的，就请看Chrome浏览器和Google Apps吧。你其实已经看到了Google Chrome OS剪影。
There will be just enough Linux in Chrome OS–thanks, in part, to Ubuntu– to support the browser and Web-based applications. You will also likely be able to run some traditional desktop applicationsusing a remote-client computing technology called “Chromoting.”Chrome OS将会有足够的应用，部分原因是Ubuntu支持了其浏览器和网络应用。你也很可能可以运行传统的桌面应用程序，通过使用叫作“Chromoting”（远程Chrome）的远客户端计算技术。
As for Android applications, where all the applications are Java-based and depend on Dalvik, I don’t see any way that those applications will run on Chrome OS.而对于Android应用程序，因为所有这些应用都是基于Java并依赖于Dalvik虚拟机的，我不认为它们可以在Chrome OS上运行。
3) Chrome OS Constantly Updated3) Chrome OS会持续不断地更新
Like the Chrome browser, you can expect Chrome OS to be patched and improved constantly. This instead of being patched to fix problems or having features added in service packs, Chrome OS, for better or worse, will continually evolve. With Chrome OS, there won’t be any wait for different versions a la Android 2.3 Gingerbread.就像Chrome浏览器一样，Chrome OS会如愿不断地打补丁与被提升。这不同于修复漏洞的补丁或为服务包加上的新特性，Chrome OS，不论好还是不好，都会不断地更新，发展。Chrome OS下，你应用软件的版本始终会是最新的。
Still having trouble visualizing it? Well, don’t worry too much. Within the next few days, we’ll have the opportunity to see Chrome OS and see how it differs from Android and other desktop operating systems.理解它仍然存在问题？不过不要太着急了。在接下来的几天里，我们会有机会亲见Chrome OS，看看它是如何不同于Android和其他桌面操作系统的。
