Hello everyone, welcome to CoderGuy (A free platform to learn different programming languages) I am Sadanand, here we'll check the OS bit version of your computer
After completing this article you'll be able to:
The memory is made up of a huge number of Bytes. Each Byte has a unique address. You can think about the memory as a street with houses, where a house represents a Byte and the house number represents the address. Now imagine that somebody decides that house numbers should always have 3 digits. That means that the lowest house number is 000 and the highest is 999. This is simple and easy, but it means that you cannot have more than 1000 houses, simply because you run out of house numbers.
It is the same for your memory: The x Bits is the number of digits you addresses have. The only difference is that the numbers are binary. A 32-bit operating system uses binary numbers with exactly 32 digits (a binary digit = a bit).
Thus on a 32bit system you can have 2^32 possible addresses which is about 4 Billion. 4 Billion Bytes are 4 GB. If your memory has more than 4 GB of space that means that you can only use 4 GB of the available memory, because you simply have no addresses for the rest of the memory.
Nowadays it has become normal to have more than 4 GB RAM and of course we want to use that memory. In this case a solution is needed and the simplest thing we can do is to increase the address space. While any higher bit number would do we'll typically simply double the number of bits from 32 to 64. Thus we have addresses for 2^64 Bytes which is 16*2^60 Bytes or 16 Exabytes.
Note that marketing people sometimes try to make us believe that 64bits operating systems/CPU's are somehow faster than there 32-bit equivalents. However this is not true. Actually increasing the address size makes things slower, because the larger the number, the more time-consuming calculations are and yes, we do calculate addresses. It is totally pointless to use a 64bit CPU/OS if your memory is small enough so you can fully address it with 32 bit.
Step 2: Look for System Type from the available list. just in front of the system type you can see the OS bit version and also on which architecture your CPU supports.
In the below example you can see there is a 32-bit OS version and 64 bit based processor, which means this system can supports up to 64 bit OS.
Method 2. (Moderate)
After completing this article you'll be able to:
- Understand the actual meaning of the OS (Operating System) bit
- Check the bit version of your computer

How to check your OS bit version as well your processor architecture?
Method 1. (Super Easy)
Step 1: Right-click on 'This PC' icon and do left-click on properties from the displayed menu.

| Right-click on This PC |
In the below example you can see there is a 32-bit OS version and 64 bit based processor, which means this system can supports up to 64 bit OS.

| OS bit version and processor architecture |
Step 1: Go to the control panel. To do so move to Start >Windows System > Control Panel
This will open the control panel on your computer
Step 2: Look for System and Security option and click over it
Step 3: Now look for System option and select it.
Step 4: Look for System Type from the available list. just in front of the system type you can see the OS bit version and also on which architecture your CPU supports.
In the below example you can see there is a 32 bit OS version and 64 bit based processor, which means this system can supports up to 64 bit OS.
You're done!
Now you know your OS bit version and it is often used at the time of software installation.
Important Point to Remember: Higher bit processor supports all types of OS for example,
On a 64 bit processor, you can install a maximum of 64 bit OS and in the above-displayed image the processor is 64 bit but the OS installed on it is 32 bit only. So all the software installed or being installed on the machine is a maximum of 32 bit.
If 64 bit OS installed on the same machine then the software installed or being installed on the machine is a maximum of 64 bit.
