Windows 32 bit or 64 bit - Tech Naandi Solutions


In this article, I will explain which is best among Windows 32 bit or 64 bit and also the difference between windows 32 bit and 64 bit.

Every new user will have this question when they are thinking to install a Windows operating system on their computer. And most of them will choose windows 64-bit over 32-bit.Without knowledge of how Windows 64-bit operating system operates and how a 32-bit operating system operates.

Today in this article you will know the actual difference between 32-bit and 64-bit operating systems. And also why you have to select Windows 64-bit over a 32-bit version.

What is Bit?

Before going into the topic lets us discuss a few things. According to Wikipedia  “A 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 described as either a 0 or 1. A computer saves your data in a collection of such bits called a byte.8-bits make up a byte.

The number of bits in a processor applies to the size of the data types that it manages and the size of its registry.

Difference between windows 32 bit and 64 bit.

A processor or CPU includes a number of registers and logic circuits. And the capacity of registers in 32-bit (x86) CPU is 32-bit and the same for 64-bit (x64).

However, a 32-bit register can store 232  separate values. So the processor with 32-bit memory locations can quickly access 232 bytes = 4 gigabytes of RAM. In the case of 64-bit, the register can store 264 different values and a processor with 64-bit memory addresses can quickly access 16 exbibytes of RAM.

Why we have to Choose Windows 64-Bit Over 32-Bit?

More RAM 

As we previously discussed 32-bit processors are only used only handling a restricted amount of RAM, and 64-bit processors are able of utilizing more RAM.🥰

In any 32-bit operating system, you can only use up to 4 GB of RAM simply because the size of a 32-bit value will not allow any more.😥 And if you want to really use all of that RAM that you installed, you’ll need to install Windows 64-bit version.😋

4 GB RAM = 2 GB In 32 Bit

Assume that you have 4 GB RAM and the 32-bit version is sufficient for you then think twice because your devices, like your video card and motherboard BIOS, take up 4 GB space, which indicates that the operating system gets access to even smaller of your RAM.

Windows specialist Mark Russinovich found that a desktop operating with 32-bit Windows with 4 GB of RAM and two 1 GB video cards only had 2.2 GB of RAM free for the operating system. So the higher and more reliable video cards get, the less of that 4 GB will be available on a 32-bit system.

Multitasking Capabilities

More RAM means that you can immediately switch between the various applications. So 64-bit version of Windows has more multitasking features than the 32-bit.🥰

64-Bit Processor Needs 64-Bit OS 

However, almost all the latest PC/laptops come with 64-bit processors and you’ll have to install a 64-bit OS on your computer to take full advantage of this 64-bit CPU.

Prevents Kernel Hijacking

Windows 64-bit OS arrives with a technology that blocks hijacking. The kernel -means prevent 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 disadvantage of the Windows 64-bit version is the shortage of availability of 64-bit software. But the vast majority of 32-bit applications will continue to work just fine on 64-bit Windows. Which involves the compatibility layer called WoW64.


This is all about which is best among Windows 32 bit or 64 bit. And also the difference between windows 32 bit and 64 bit.
