Hi,
This 32-bit and 64-bit thing baffles me. It's not often that I run across it, but when I do, it baffles me. Like when I want to download software from
http://www.google.com/ime/transliteration/
it asks me which version to download.
I have win XP running on my thinkpad machine. How do I find out if my hardware is 32-bit or 64-bit. Also, how do I find if OS is 32-bit or 64-bit and thus how to know which version to download from this link. Also for any installed application say firefox, how do I know which bit version is installed.
How popular are 64-bit hardware/OSs?. Are all the new CPUs and OSs supporting 64-bit and 32-bit for backwards compatible or 64-bit is still a luxury?
Thanks,
