There is for Windows OS and Linux. Google hasn't yet created a version of Chrome that runs on iOS, unfortunately. Why? Nobody knows really, other than the fact that 64bit isn't significantly better than 32bit. The only reason 64bit is better is due to the fact that it can allocate more memory (RAM) from the computer. Even then, 64bit is not a great improvement to 32.
You're probably wanting a 64bit version of Chrome so you can run JAVA plugins, right? I know it sucks, but in order to run certain plugins you'll need to use a different, 64bit browser.
Sorry I cant help you, but I hope I taught you something :)
You can check in the settings of the Chrome. It will tell the version as well as the bit size of browser.
Yes Google Chrome is available for 62 bit systems as well. It could be downloaded from the Google's website.
no
You can always select the theme which suits you best. All themes are kept keeping the chrome's size in mind.
I believe that will be Opera. Opera beats Google Chrome at speed only a little bit. Try Opera you'll love it.
You can see the speeds of download in the download option. It is present in the menu of the Chrome.
Yes, Google Chrome can work on a desktop/laptop with Windows XP SP3.
sign in to Chrome, and sync your data, Enter a Sync Passphrase if needbe I may be misunderstanding your question, so look around a bit more, maybe check the google forums
Yes. Google offers both 32-bit and 64-bit binaries for Linux on Google Earth's download page.
There are only a few number of browsers specifically for 64 bit computers. I would say the fastest 64 bit browser is Waterfox. Dowload it here: http://www.waterfoxproject.org/ If you have a 64 bit laptop I would still recommend you to use Google Chrome as it's the fastest browser now. Dowload Chrome here: https://www.google.com/intl/en/chrome/browser/
Google Chrome (My personal favourite) and Mozilla Firefox are the two most popular internet browsers. Google Chrome is faster and more simplistic(but still greatly open for customization), but Mozilla Firefox is a bit more tailorable to your own style.
While Google Chrome is a bit faster then FireFox, Google Chrome often renders pages incorrectly and has trouble with some websites, although it at first appears to be cleaner then FF, FF can be customized and icons can be removed or made smaller, however you can't remove the file bar in FF that is considered useless to some people due to the keyboard shortcuts, GC has no file bar and doesn't present this problem and the keyboard shortcuts still work, FF has many add-ons and customizations, while Google Chrome has none.
