32-bit or 64-bit, which to choose?

One questions that I find most users asking these days is that which version of operating system to choose? 32-bit or 64-bit? Well, just like anything else, both versions have their own advantages and disadvantages but as a general rule of thumb, if your device (Laptop, PC or etc.) has 4GB RAM or more you should go for the 64-bit OS. There are mainly two reasons for that:

  1. 32-bit operating systems don’t support more than 4GB RAM.
  2. 64-bit operating systems are good at handling larger amount of RAM.

Now the next question that comes to one’s mind is that does my device even support a 64-bit OS? Well, that depends on how old it is. Almost all of the new devices now support 64-bit OS but this generally depends on the processor (also called CPU) of your device. If you’ve a 64-bit CPU than you can easily run a 64-bit OS. Though, one thing that you might need to check is that does your device manufacturer have 64-bit drives available for you. If not, than you would be able to run the 64-bit OS but not utilize it’s full potential and in that case, it’s better to stick with the 32-bit version of your OS.

Unfortunately, that is not it. Even if you’re device is capable of running a 64-bit OS and it has compatible drivers, another thing that you might want to look into is that if the softwares that you use have 64-bit versions available. In my experience, 32-bit applications run flawlessly on a 64-bit OS but not without a few exceptions (mostly anti-virus programs).

To sum it all up, if you’ve a device with 4GB or more RAM and was manufactured in or after 2013 than you probably should go for a 64-bit OS. Otherwise, you can either stick with your current OS or it’s about time you got a new device.
