32 bit vs 64 bit

When downloading a program, we may asked for 32/64 bit system, what is it?

64bit v 32bit
The most fundamental difference is 64 bit handles process faster than 32 bit. To install 64-bit OS version we should have a CPU that is capable to running 64-bit OS versions. 64-bit operating systems can be more responsive when running multiple programs at the same time and often switch between programs.



- The most significant difference is 64 bit OS can handle up to 192 GB of Random Access Memory (RAM) while 32 bit just 4 GB,
- Then, 32 bit OS will have a trouble while handling file larger than 4GB
- 64 bit OS is more secure, because it's driver has certificate from each vendor
- We can run 32 bit software on 64 bit OS, while we can't run 64 bit software on 32 bit OS
- Smallest unit has 32 bit size on 32 bit OS, while on 64 bit OS, smallest unit has 64 bit size
