Unlike other modern web browsers, which can only run one process at a time, Google Chrome will give each tab its own process. This speeds up overall performance and saves the entire browser from crashing when one tab causes problems.
The multi-process design requires more memory allocation up front but less memory over time as users tend to multitask. It also prevents your computer from slowing down after you browse for an extended period of time and open/close lots of tabs.

Where is Google heading, and what it wants to achieve with with Chrome? Perhaps best summarized by Sam Schillace from Google ( and mentioned in Next Google [webmasterworld.com] thread [Admin Note - subscription required]):
Prior to Google, everyone said search was done. But the point was that search could have been a lot better. The same is true of browsers today...
The current generation of browsers can already run some pretty sophisticated applications without having to install software, and it's starting to extend to mobile devices too. The next generation of browsers, and the web applications that run on them, will make communication and collaboration even more transparent and let me focus on what I really want to do — connect with the person at the other end and get work done together.
