What is the Difference between 32-bit and 64-bit Processors


There are many things to consider while buying a laptop or a computer, we look for Ram size,Processor, CPU, GPU, Hard disk and Display etc; But when it comes to select a processor category we generally prefer a 64-Bit processor. Many people want a 64-bit processor even without knowing what it means to have a 64 bit processor and what is the difference between a 32-bit and 64-Processor.

It is good to have knowledge of many terms which we use daily but people don't give much attention in this article lets see the difference between 32-bit and 64-bit processors and what it means to your PC.

Difference between 32-bit and 64-bit Processors:

whenever you buy an operating system, a game,a software you probably see 32-bit and 64-bit options available if you are a windows user you must have observed two program files folders one simply labelled as :- "Program files" and the other labelled as "Programfiles(x86) " .This folder
"Program files" contains DLL files of  64-bit applications. While "Programfiles(x86)" contains DLL files of the 32-bit applications.

To install a 64-bit version of windows you need a CPU that is capable of running a 64-bit version of windows. The benefits of using a 64-bit operating are most apparent when you have large amount of RAM installed on your PC, Typically 4 GB or more.


In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, and a 64 bit operating system will be more responsive while running several programs at the same time and switching between them frequently.

A computer with a 64-bit processor can have a 64-bit or 32-bit versions of operating system. However,when running a 32-bit operating system the processor would not run at its full capacity.

How does a 64-Bit processor handle more RAM efficiently :

The computer system supports only binary system which comprises of the digits "0" and "1", Each one is considered as a bit . That means for 1-bit computing there are two possibilities, 2-bit means 4 values , Then at 3-bit it will be 8 values.

If we keep going exponentially we will eventually get 32-bit (2 to the 32nd power) worth 4,294,967,296 and 64-bit ( 2 to the 64th power) worth 18,446,744,073,709,551,616 values.

That's a lot of bits and this shows how much more powerful a chip that supports higher bit computing can be. It's a lot more than double . So it's quite obvious that 64-bit processor is capable of doing more computing than 32-bit in a given time.

Things you must note before buying Laptop

There are several things we should keep in mind while buying a laptop. You might have seen people regret about what they have bought believing in the words of sales persons So these are certain things one needs to observe  RAM and Storage:  R am would be the First thing anyone would probably ask about while buying a lappy .Generally we see 4 GB ram in most low cost laptops , but it is always preferable to take one with a minimum of 8 GB's of RAM The next thing is the Permanent storage device, it is common to buy a laptop with a hard disk of  1 TB and there is no chance of getting fooled around in this matter. 2.Processor : M any are aware of these processors but the thing you need to know  is the generation of  these processors currently 7th gen processors are the latest ,we need be aware of this as 6th gen processor may vary some thousands of rupees in cost and will be a bit slow compared to the latest ones  We should also be aware that a i
