We made a video a while ago talking about the use of 64 and 32 bit systems, both in Linux and Windows. In today’s post we will take up a little of this idea and discuss when each of them can be used.
Operating systems can be designed to be used on top of 32 or 64-bit processors, whereas a 64-bit system cannot run on a 32-bit processor, but a 32-bit operating system can run on a processor 64. This means that you can use a 32-bit operating system on both 32-bit and 64-bit processors.
However, if using Windows, a 32-bit system will not be able to recognize more than 4gb of RAM (Except in special versions for servers), this means that you may be wasting memory if you have more memory than that. For Linux, on the other hand, we have a resource accessible to practically all distros called “Kernel PAE”, and “PAE” is an acronym for “physical address extension”. The PAE kernel allows more than 4 gigs of RAM to be recognized, but the question remains: when should we use a 32-bit system and when should we use a 64-bit system?
Well, the practical answer is: When your FOR 32-bit processor.
And for that, you may have to go back in time to easily find a processor that is not 64 bits. If you have a 64-bit processor, choose to run a 64-bit system, because if you run a 32-bit system on a 64-bit system, in addition to wasting some of the performance of your processor, you may be playing a little bit of RAM out.
There are people who prefer to put 32-bit systems on low memory machines like netbooks for example, because 64-bit systems end up using a little more RAM than 32-bit systems, although it is still not the best thing to do. because you end up not taking better advantage of CPU processing and the impact on RAM, it ends up not being that big.
If you have not understood what processors have to do with choosing a 32 or 64 bit system, watch the video below, so you can better understand the relationship between them.
