The terms 32-bit and 64-bit refer to the way a computer’s processor to handling the information. The 64-bit version of Windows handles large amounts of Random Access Memory (RAM) more effectively than a 32-bit system.

What is Bit?

A bit is the smallest unit of measurement used for information storage in computers. A bit is represented by a 1 or a 0 with a value of true or false, sometimes expressed as on or off. For example: The capital letter “A” is expressed digitally as 01000001.

 32 bit and 64 bit os:


The main difference between a 32 bit and 64 is that 32 bit system has 4 GB of space for addressing means that the 32 bit system has a limit of 4GB RAM to process data whereas 64 bit version can efficiently handle more than 4 GB of RAM.


If we compare 64 bit with 32 bit OS, 64 bit is faster and performs more upgraded silicon processes and have more no of transistors which proves it to be more advantageous than 32 bit.


When using 4GB RAM with a 32bit Windows there will only be 2.7 to 3.2GB available, the rest is reserved for Hardware.


The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer (typically 4 GB of RAM or more). In such cases, a 64-bit operating system can be more responsive when running several programs at the same time and switching between them frequently.

Confusing questions:

Which version of windows should I install?

If you have 2 GB RAM, 32 bit is the best and for 4 GB or higher you should go for 64 bit installation.

How to know the bit installed in my computer?

Right click on computer and then properties.

Can I change my bit of my windows?

Yes, but you need to reinstall OS with windows disk.

 Can I use 32 bit software in 64 bit windows?

Most software are designed for the 32-bit version of Windows will work on the 64-bit version of Windows but some doesn’t.

Can I use 64 bit software in 32 bit windows?

If the software is specifically designed for the 64-bit version of Windows, it won’t work on the 32-bit version of Windows.

I am using 64 bit and I migrated to 32 bit, do I need 32 bit drivers?

Of course, you need to install all the drivers of 32 bit only. So, if you are planning to migrate from 64 bit to 32 bit you must have all the device drivers to work with.
