Google also says that Chrome increases security in another way, by essentially running each tab in an individual sandbox. The sandbox is closed off from the rest of your PC, Google claims. It can't write to your hard drive, or read files from certain areas of your PC such as your Desktop. According to Google, this will help eliminate malware infections.

Application windows: Building a browser for Web 2.0

If you need any evidence that Chrome has been built for AJAX and for applications delivered via the Web, look no further than what Google calls application windows. An application window is a special Chrome mode designed for Web-based applications such as Gmail, Google Calendar and any other Web-based application.

Create a desktop shortcut to an application window by running the Web-based application, clicking Chrome's Page icon and choosing "Create application shortcuts..." That creates a shortcut on your Desktop, Start menu or Quick Launch bar to the application. Double-click the icon, and the Web-based application runs in a browser window with no browser controls -- no tabs, buttons, address bar, etc. All you see is the application itself, although there is a small drop-down menu in the header that offers various browser functions such as back, forward, print and duplicate. Right-clicking also gets you to functions such as back and forward.

In this way, you could have your desktop full of shortcuts to all of your Web-based applications -- word processing, spreadsheets, CRM and so on. When they run, they appear to be an application running on your PC.

This feature still needs a bit of fine-tuning, because different Web-based applications work differently in it. In Gmail, for example, when you click a mail message, it opens directly inside the application window, which is how you expect it to work. But in Google Docs, when you click on a document, the new document instead opens in a new browser instance, complete with the normal browser interface.

A lot of nifty extras

Buried beneath Chrome's bare-bones exterior are hidden some very nice extras, many of them for self-described nerds and techies. One of the niftier features is the Task Manager, an applet similar to Windows' Task Manager. It shows each separate process being used by Chrome and displays memory use for each, as well as the CPU use each takes up. And it also shows which are currently accessing the Internet or network, and the current access speed.

If you want to free up RAM or CPU, click any process, click "End process" and voila — the process is gone. It's a great tool that offers sometimes surprising information. For example, it showed me that a Shockwave Flash plug-in took up 31MB of RAM and quite a bit of my CPU, even though I wasn't watching any Flash videos or content. I used the Task Manager to shut it down and freed up both RAM and CPU usage.
