Difference Between 32-Bit vs 64-Bit


32-Bit vs 64-Bit : So here is the difference between 32 bit vs 64 bit

In the computer world, 32-bit and 64-bit refer to the type of central processing unit, operating system, driver, software program, etc. that utilizes that particular architecture. You’ve probably seen the option to download a piece of software as a 32-bit version or a 64-bit version. The difference does in fact matter because the two were programmed for separate systems.

What bit you have??

go to start menu and search for system . you will see the bit which you have.so let’s talk about differences.

Same but different 32-Bit vs 64-Bit :

The best example of this distinction is right inside your document system. If you are a Windows user, you have probably noticed that you’ve got two Program Documents folders: One tagged only Program Documents and the other tagged Program Files (x86).

Programs use shared resources on a Windows system (known as DLL files), which can be structured differently based on if it is used for 64-bit programs or 32-bit software. If, for example, a 32-bit program reaches out to get a DLL and finds out that a 64-bit edition, it is only going to quit functioning. That is the problem.

32-bit (x86) architecture has existed for a lengthy period, and there are still a range of programs that use 32-bit structure — though that is changing on several platforms. Modern 64-bit systems may operate 32-bit and 64-bit applications due to an extremely straightforward and effortless solution: 2 different Program Files directories. When 32-bit programs are sequestered into the proper x86 folder, Windows understands to serve the ideal DLL – the 32-bit edition.

Architecture and Software Description 32-bit architecture is based on registers, address or data buses 32 bits (4 octets) wide. For software, 32-bit typically means the use of 32-bit linear address space. 64-bit architecture is based on registers, address or data buses 64 bits (8 octets) wide. For software, 64-bit means code to use with 64-bit virtual memory addresses.
Compatibility 32-bit operating systems (OS) and applications require 32-bit CPUs 64-bit OS requires 64-bit CPU, and 64-bit applications need a 64-bit OS and CPU
Systems Available All editions of Windows 8, Windows 7, Windows Vista, and Windows XP, Linux XP Professional, Windows Vista, Windows 7, Windows 8, as well as Mac OS X and Linux
Memory Limits 32-bit systems are limited to 3.2 Gigabytes (GB) of RAM 32 bit Windows with address limitation do not attain to a full 4GB. It’s hardware dependent, typically 3.25GB. 64-bit systems allow up to 17 Billion GB of RAM.
Pros Fewer issues, more widely compatible • More RAM access • More efficiency • More virtual memory allocation • More security features
Cons Less RAM access, less memory, less efficiency, fewer security features • Possible driver compatibility • Some motherboard RAM limits • Legacy issues


One thing to remember is that a 64-bit processor can support both 32 bit vs 64 bit OS but a 32-bit processor can only run 32 bit OS.


SO What Do They Mean?

  • 32-bit hardware and software is often referred to as x86 or x86-32.
  • 64-bit hardware and software is often referred to as x64 or x86-64.
  • 32-bit systems utilize data in 32-bit pieces while 64-bit systems utilize data in 64-bit pieces.
  • In general, the more data that can be processed at once, the faster the system can operate.32-bit vs 64-bit


If you are installing any working OPERATING SYSTEM it’s far very important to know what kind of processor your pc has and ensure which you deploy the right one. With this, it is also essential which you recognize the type of operating system your computer is running. modern-day systems have 64-bit processors which provide better overall performance from many aspects. They provide higher memory utilization, rapid functioning of the system. They also have greater memory utilization when compared to 32-bit processors. So It is the best option to buy a 64-bit operating system with 64-bit applications which help in providing the best performance.

So now, you have learned these few things:

  • Your computer can have either 32-bit or 64-bit processor
  • Your operating system can be 32-bit or 64-bit
  • A computer with 64-bit processor can run both 32-bit and 64-bit operating system
  • A computer with 32-bit processor cannot run 64-bit operating system.32-bit vs 64-bit
