What is the difference between 32 bit operating system and 64 bit operating system

Microsoft Windows operating system is most popular operating system in the world.Windows operating system comes in two flavors.

i. 32-bit operating system

ii. 64-bit operating system.

In today's topic iam going to explain what is the difference between 32 bit and 64 bit operating system and what are the advantages and disadvantages of the 32-bit and 64-bit operating system. First of all check is your system supports 64 bit or not... check out my previous article... IS Your System Supports 64 bit operating system or not




Difference between 32 bit operating system and 64 bit operating system

1. The main difference between 32 bit operating system and 64 bit operating system is support for the RAM. A 32 bit windows operating system cannot support more than 4 GB RAM and a 64 bit windows operating system supports  up to 128 GB RAM. So if you are using more than 4 GB RAM with 32 bit windows operating system then it useless..

2.A 64-bit windows operating system is more protected and having more security features compared to 32-bit windows operating system.

3. In 32 bit operating system each and every program can use only 2 GB of memory  but now a days games, video editing softwares and programs requires more than 2 GB.  A 64 bit operating system attaches upto 8 TB memory to each and every program or game...

4. A 64 bit operating system can perform the data processing more fastly compared to 32-bit  operating system.

Disadvantages of 64 bit operating system


1. To install 64 bit operating system in your system you need to have 64 bit CPU.

2. A 64 bit operating system takes more amount of Hard Disk Space and memory.

3. A 32 bit Operating system and software's will run on 32 bit operating system as well as 64 bit operating system but a 64 bit operating system will run only on 64 bit CPU.

4. Having the issues such as not all the hardware devices in the system having the compatibility with 64 bit operating system.


When to choose 32- bit operating system and 64 - bit operating system


1.  If you are using more than 4 GB of RAM then you must install 64-bit operating system instead of 32-bit one.

2.  If your processor having 64 bit support then you can install 64 bit operating system.

3. If you are using Video editing softwares or Adobe PhotoShop CS6 or playing 3D Games then install 64-bit operating system .

4.If you are using hardware devices such as printers and scanners then you must check the driver support for 64 bit operating system before installing.

5. If a device driver designed specially for 32-bit operating system then it will not work with 64-bit operating system..
