Operating SystemComputer ProgrammingWindows Server

In computing, a byte is the unit of data and processing of data is generally denoted as bit processing. In general, there exist two types of processors namely a 32-bit processor and a 64-bit processor.

Sr. No.Key32-bit OS.64-bit OS.
1Data and storage handling.As the name suggests 32 bit OS handle and store less data as compared to 64 bit OS. More specifically 32-bit OS can address a maximum of 4 GB 4,294,967,296 bytes) of RAMOn the other hand, 64 bit OS can handle more data than 32 bit OS, in numbers, it can address 264 memory addresses, i.e actually 18-Quintillion GB of RAM.
2System compatibility.A system with a 64-bit processor can run either of a 64-bit or 32-bit version of an operating system installed.On the other hand systems with a 32-bit processor could run 32 bit OS properly but 64-bit OS would not run at its full capability.
3PerformanceThe 32-bit processor as compared to the 64-bit processor is less efficient in a factor of performance.On the other hand, a 64-bit processor is more recommended for multitasking and other heavy application execution due to its high performance as compared to a 32-bit processor.

Check the version of Operating System

In windows

Click on Start icon-search/type system in the Start Search box, and then click system in the Programs list. The operating system is displayed as follows: For a 64-bit version operating system, 64-bit Operating System appears for the System type under System. For a 32-bit version operating system, 32-bit Operating System appears for the System type under System.
