豆知识 2011-05-22&05-28 带你认识谷歌操作系统

 So, you are on the Internet using a web browser 1. You know that thing with the address bar, and back button, and bookmarks. That thing you are in right now, up there, yeah, that's your web browser. 

If you like me when you’re on your own computer, you spend something like, I don't know, 90 percent of your time on the Internet in a browser. There’s emails, chatting; you’re reading news, watching videos, playing games, buying things, just to name a few, which kind of makes the web browser the most important program on your computer. And if you think about it, it hasn't always been this way. 
You see, web browsers 2 were first designed a long time ago with the old Internet in mind. You know back when it was slow, and mainly just words with links that just send you to more words with links back before all of these innovations. So some guys at Google asked, “What if we redesigned the web browser from scratch with an eye towards the new web?” You know, maps, video, and web apps that are a lot more dynamic. And so they created Chrome, a web browser that’s crazy faster on today's Internet. And it's slick and more secure. But mostly, it's really fast. I mean my biggest question when I boot up my computer is how long till I get on the Internet, right? I mean if there isn't any Internet, I might not even use my computer. Did you know that even the fastest computers will still take like 45 seconds to boot up. 45 seconds! You can make a sandwich in that time. 
So here is what's going on when your computer is booting up. There’s a list of things to do. Stuff I’m sure you don't care about, but it cranks through them one at a time. What you probably notice is that your programs begin loading up slowly and if you like me, as soon as you see your web browser icon 3 appear, you’re double clicking it over and over and over...”Let's go, buddy 4, I got some emails to read.” Well, all this stuff is called your operating system. And over time it gets rusty 5 and you once fresh computer gets slow. 
Well, Google was like, “Wait a second. If your operating system is a hassle, and all you’re really using it for is to get on your web browser, to get online, then maybe we don't need this anymore. What if when you pressed on, you were on internet in seconds? What if your browser was your operating system? So check this out. This means you don't have to deal with managing programs or nagging 6 updates or lost files or confusing settings or blue screens of doom 7. And there’s no nagging updates, just your browser, which means you can still listen to music, you can watch movies, interact with friends, you’re creating documents, you’re playing games, you’re writing your email… You’re doing all this stuff that you’re already doing on the Internet. But here is the thing: none of this is stored on your computer. What? None of it, you asked? Yeah, none of it. Really nothing? Yeah, nothing is stored on your computer. 
Well, where is it? It's on the Internet. You know, like when you access your emails from your computer and your phone, the email isn’t stored on either device. 
So if everything is stored on the Internet, then your phone, your computer, all of these devices are what people call stateless, which is kind of a big word, so maybe just remember this: Chrome is a totally rethought web browser. You can download it right now on your computer. But Chrome OS is a totally rethought computer that lets you stop worrying about your computer, so you can focus on the Internet, which is what most of us use our computers for nowadays, anyways.
