Even if you are not an IT geek, you must know about the bit version of your Processor, Operating System and lots more. If you are unaware about the versions lets know something simple about that. Currently there are two bit versions which are easily available in the market. They are 32-bit version and 64-bit version. 64-bit version of hardware and software is built with the improvement in 32-bit systems. You may have lots of questions about the differences in 32-bit and 64-bit, let’s see some of it.
What is the Difference?
The way a CPU handles information is referred by the 32-bit and 64-bit terms. A large amount of RAM can be handled more efficiently by 64-bit version of Processors and Windows which is impossible with 32-bit version.
Can I use 32-bit OS in 64-bit processor and vice-versa?
You can use both 32-bit and 64-bit OS in your 64-bit processor and will work fine, but the 64-bit OS in 32-bit may not work. If you have 64-bit processor then I recommend you to use 64-bit OS by which your resources will be fully utilized.
If You Are Using Windows
If you want to know about the bit version of your Processor, To look about the required information you have to open System information.
You can go through the following steps:
Step 1: Open Start menu.
Step 2: Click on programs.
Step 3: Click on Accessories.
Step 4: Click on System Tools.
Step 5: Click on System Information and under System Summary look for System type.
If there is X86-based PC then it’s a 32-bit computer and if there is X64-based PC then it’s a 64-bit computer.
And if you want to know about the bit version of your Operating System then
Step 1: Open Start menu.
Step 2: Click on Control Panel.
Step 3: Under System and Security Click on view amount of RAM and Processor Speed. Under the System there is the bit version of your OS.
If You Are Using Linux
If you want to know about the bit version of your Linux
If you want to know about the bit version of your Linux distribution then you can use a command line program named uname. It will tell you exactly the bit version of your OS. To use uname go through the following steps:
Step 1: Go to Applications
Step 2: Select Terminal which is under Accessories. A black terminal window like DOS will be opened.
Step 3: Type uname –m in the terminal window and hit enter.
- If i686 is the response then you have 32-bit version Linux.
- If x86_64 is the response then you have 64-bit version Linux.
What about the Processor?
If you want to know about your processor then open Terminal going through the above Steps (Step 1 and Step 2). After opening the Terminal type: cat /proc/cpuinfo or you can type: grep flags /proc/cpuinfo. Both will give you the same result.
There you can find three modes:
- Lm flag, which denotes Long mode and says your CPU is of 64-bit.
- Pm flag, which denotes Protected mode and says your CPU is of 32-bit.
- Rm flag, which denotes Real mode and says your CPU is of 16-bit.
