Operating systems are a collection of code which helps to execute the instructed work by the hardware or in another language; it is a collection of software which helps computers to execute the required task. The major differences of the operating system are the bit version of them. In general cases there are mainly 32 bit and 64 bit versions are available in the market of an operating system. This is same with windows and Linux also. Here are some of the basic differences between the 32 bits and a 64 bit operating system:
32 bit operating systems can have maximum 4 GB of RAM. In most of the cases these days motherboards comes with the capability of having 32 GB of RAM. Most of the slots remain unused in case of 32 bit version of an operating system. Most of the 32bit version is capable of executing in both versions of the operating system, but an application made for 64 bit operating systems in general cases does not execute in 32 bit operating systems. Most of the processors from the major processor makers AMD and Inter come with the 64bit compatible format which makes them easy to operate with a 64 bit operating system.
