Which version of    Windowsdo I have to choose —     Windows    64-bitor    32-bit? What is the     difference between 32-bit and 64-bit?  
  Every newbie face this question when they are planning to install Windows operating system in their computer. And most of the them    choose Windows 64-bitover 32-bit, unaware of the fact – how Windows 64-bit operating system     outperforms 32-bit.

  Today in this article we are going to break down it for you, today you will know :
  
       
  • What is the difference between 32-bit and 64-bit ?   
  • Why you have to choose  Windows 64-bit over 32-bit version ?  
  “Bit” stands for :  

  What is this “    bit” stands for :  
      Wikipediasays –    ” The bit is a basic unit of information in computing and digital communications “. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a    0 or 1. A computer stores data in a collection of such bits known as a    byte.    8 bitsmake up a byte, also called an    octet.  
  The number of bits in a processor refers to the size of the data types that it handles and the size of its registry.
  What is the difference between 32-bit and 64-bit ?  

  A processor or CPU includes a number of    registersand logical circuits. And size of registers in 32-bit (    X86) CPU is 32-bit and similar for 64-bit (    X64).  
  And a 32-bit register can store    2      32    different values. So a processor with 32-bit memory addresses can directly access 2    32bytes =    4 gigabytes of RAM. And in case of 64-bit, register can store    2      64    different values and a processor with 64-bit memory addresses can directly access     16 exbibytes of RAM.

  Why you have to choose Windows 64-bit over 32-bit ?  

  1.          More RAM      

  As we already said 32-bit processors are only capable of handling a limited amount of RAM, and 64-bit processors are capable of utilizing much more.
  In any 32-bit operating system, you are limited to 4 GB of RAM simply because the size of a 32-bit value will not allow any more. And if you want to actually use all of that RAM that you installed, you’ll need to install Windows 64-bit version.
  So when it comes about RAM in    32–    bit vs 64-bit: 64-bit always wins.  
  2.      4 GB RAM = 2 GB in 32-bit      

  Suppose you have 4 GB RAM and 32-bit version is enough for you then think twice because your devices, like your video card and motherboard BIOS take up room in that same 4 GB space, which means the underlying operating system gets access to even less of your RAM.
      Windows expert Mark Russinovichfound that a desktop running 32-bit Windows with 4 GB of RAM and two 1 GB video cards only had 2.2 GB of RAM available for the operating system—so the bigger and better your video cards get, the less of that 4 GB will be accessible on a 32-bit system. (Source :    LifeHacker)  
  3.      Multitasking Capabilities      

  More RAM means that you can quickly switch back and forth between the different applications. So 64-bit version of Windows has more multitasking capabilities than 32-bit.
  4.       64-bit Processor Needs 64-bit OS      

  Almost all the modern PC/laptops are comes with 64-bit processors and you’ll have to install a 64-bit OS on your machine to take full advantage of this 64-bit CPU.
  5.      Prevents Kernel Hijacking      

  Windows 64-bit OS comes with a technology that prevents hijacking the kernel – means prevents unsupported changes to the kernel of the Windows OS – along with support for hardware-enabled data execution protection, and mandatory digitally signed 64-bit device drivers.
  The only drawback of Windows 64-bit version is lack of availability of 64-bit softwares. But the vast majority of 32-bit applications will continue to work just fine on 64-bit Windows, which includes a compatibility layer called    WoW64, which actually switches the processor back and forth between 32-bit and 64-bit modes depending on which thread needs to execute—making 32-bit software run smoothly even in the 64-bit environment.  
  So switch your Windows 32-bit version to 64-bit today and  get most out of your system.
