32bit vs 64bit

Okay I know this has been known for like ages but I just actually "know" it. I've encountered these bits before but never really try to understand them and seems like they have no significant benefits for me the last few years.

Just for simple intro, basically there are 2 versions of Windows which is the 32bit and 64bit. Just by the number you can tell that the 64bit handles more memory (the RAM to be exact). And the best thing about it, it works better in handling multiple programs running at the same time - more responsive.

A 32bit version of Windows can only handle RAM up to 3.0 - 3.5Gb. Meaning to say, if you installed a 4Gb RAM on a 32bit Windows, it doesn't utilize the 4Gb capacity fully. The maximum is still 3.0 - 3.5Gb even if you have installed a 10Gb RAM. The 64bit windows can utilize more than 4Gb RAM.

To install a 64bit version of Windows you need to make sure that your processor is capable of running a 64bit version of Windows - very Important!

32bit programs mostly work on a 64bit version of Windows - mostly. But 32bit driver won't work.
64bit programs won't work on a 32bit version of Windows and so as the driver. 64bit driver won't work on 32bit version of Windows.

There's a hell lot more info regarding this bits, so keep updating and sharing ya'll~
