Most of you may have heard of the 64 bit and the 43 bit options when it comes to your laptop’s operating systems and are probably thinking about upgrading. However, most people do not really understand the difference between the two. Neither do most people generally know which one is better suited for their needs. In most cases, people just opt for what is bigger without knowing why.

Apparently, more and more people are starting to get the 64 bit operating systems installed and are replacing the 32 bit which was previously in their system, thinking that the original is now less capable of functioning. This article will try to explain the very basic differences between 64 bit and 32 bit operating system versions.

The 32 Bit

The first thing that you should know about an operating system with the 32 bit version is that it only has the capacity to store 4096 MB of RAM. Each of the processes are allocated at least 4GB whereas the 2GB is allocated for apps use at any given time. More modern chips allow the use of PAE which extends the capacity of the operating system to 64GB. However, the PAE needs an additional application to function and most of the applications don’t have it.

A lot of people believe that this a problem which is specific to Windows alone but it also affects the Linux and Mac operating systems. In Linux, a special mapping table is used to gain access to additional memory whereas the Mac has a 34 bit kernel by default. Windows have a 4GB limitation in memory storages due to certain licensing technicalities. The motherboards also require access to this allocated 4GB , therebycutting the RAM that the operating system can use.

The 64 Bit

The 64 bit, on the other hand can access about seventeen billion gigabytes of memory in its system which basically means unlimited memory! In the 64 bit version, the video cards or the motherboard is not making use of the memory that applications should be using. In the 32 bit version, only 2GB is allocated per process whereas in the 64 bit version, there is over 8 TB worth of virtual memory for each process stop use. This is a significant difference between the two versions of operating systems. You will require this much RAM if you are doing plenty of video editing on your laptop.

Therefore, the only major difference between the two is the amount of RAM space you can utilise. In order to know if upgrading to the 64 bit is the best way forward for you, consider the kinds of things that you do with your system. If you edit massive amounts of videos and images, you might need the 64 bit version of the operating system. However, if you are only going to do basic computing work on your laptop, there is absolutely nothing wrong with sticking to the 32 bit version.
