32-Bit Vs 64-Bit Windows OS: What Is The Difference? How To Choose?

Short Bytes: A common confusion occurs when we have to choose between a 32-bit Windows and a 64-bit OS because many of us have no idea about what is the difference between them. After reading this article, you get an upper hand while choosing one of them.

Microsoft Windows comes in many variants with barely visible feature differences. A noticeable variation is observed when we have to choose between a 32-bit or a 64-bit version. Lack of knowledge regarding the basic difference between a 32-bit and a 64-bit operation system adds to the puzzlement when it comes to deciding the appropriate version.

Microsoft started releasing 64-bit versions shortly after the launch of their well-liked and fantasized Windows XP, which had the longest product lifespan of around 14 years. Time-traveling into the history reveals that the very first implementation of the 64-bit operating system was a Unix-like UNICOS created by the supercomputer-maker Cray Inc. in 1985. The development continued and many operating systems — Mac OS X, Windows, Solaris, and the most recently Google’s Android — were baked into their 64-bit versions.

The operating system variants are designed to utilize a kind of processor architecture and named so accordingly. A 32-bit OS is designed to take advantage of the resources facilitated by a 32-bit processor (like Intel’s x86) and same is the case for a 64-bit OS. So, the topic that should be discussed first is the processor.

A ‘bit’ of knowledge

What does a bit stand for? The smallest piece of data in a computer is known as a bit or binary digit. We know that computer only understands binary language (the 0s and 1s), so, each and every bit can have only one binary value, either 0 or 1. A computer stores data in a collection of such bits known as a byte. 8 bits make up a byte, also called an octet.

Something about the 32-bit vs 64-bit processors

A processor or CPU includes a number of registers and logical circuits. Also called the brain of the computer, people often confuse CPU with the cabinet of a desktop computer. The size of the register is 32-bit in a 32-bit CPU and similar for 64-bit. The number of values that can be stored in its register are 2^32. These values are used to map the address of the memory locations present in the physical memory. So, 2^32 = 4 gigabytes is the amount of memory or RAM a 32-bit processor can access during its operation.

In the case of 64-bit, the register can store 2^64 values that amount to 16EB (exabytes) of RAM. A grand figure when to compared to 4 GB memory that could be accessed by its 32-bit older counterpart.

A 32-bit CPU can process 4 bytes of data in one CPU cycle as 8 bits are equal to 1 byte. So, if the size of the data to be processed is greater than 4 bytes, it would require the CPU to go for another cycle to process the remaining data. In the case of a 64-bit CPU, the whole data, if less than 8 bytes, could be processed in a single go. Even if the data is more than 8 bytes, the 64-bit processor would require less time than the other one. You’ll not be able to notice much difference in normal day usage, except that you are the one who likes to multi-task between heavy applications. A 64-bit processor comes in multi-core options enabling more processing power without increasing the size of the hardware.

The difference: 32-bit vs 64-bit Windows OS

The 64-bit operating systems are designed to support more RAM than the 32-bit ones. Heavy applications like image editing software, AutoCAD, and games could have a considerable performance boost after your machine is packed with 16 exabytes of RAM, at least theoretically. The limit of physical memory that can be used, depends on the fact whether your motherboard will accept it or not. Practically, you don’t need hundreds of gigs of RAM for gaming sessions. Read here about how much RAM do you need for gaming.

The minimum amount of RAM required for a 64-bit OS is 2 GB in comparison to 32-bit Windows which requires 1 GB RAM. It’s somewhat obvious because with large-sized registers more memory will be required. You should pack a memory chip of size 4 GB if you wanna experience the 64-bit Windows in action. The Home edition of Windows 10 can deal with 128 GB while the Pro has some serious limits, up to 2048 GB. You can stuff your machine with as much RAM you like.

Another reason that accounts for its widespread adoption is that it has now become more difficult to map files in the physical in memory. This is because the average size of the files is rocketing by the tick of the clock, usually more than 4 gigabytes.

One thing that you need to keep in mind is that a 32-bit OS works fine with a 64-bit processor but it won’t do any wonders. You’ll have to install a 64-bit OS on your machine to take full advantage of the 64-bit CPU. Also, the drivers and applications used should be designed for 64-bit processors.

Windows 64-bit version offers Kernel Patch Protection which prevents unsupported changes to the kernel of the Windows OS along with Data Execution Prevention at the hardware level. A digital signature for all the drivers is a must in order to prevent installation of modified drivers which may be used to inject malware on the machine.

The lack of software availability is a major downside for the higher bit operating system. Most of the older legacy software and drivers may not run on the 64-bit Windows. Many developers and companies are coming up with newer versions of their software products with improved compatibility. Mozilla released the 64-bit version of their Firefox browser back in December. Its adoption rate has made a considerable jump in the last decade as various manufacturers and the Windows-maker have made continual efforts to ship the 64-bit Windows either pre-installed or along with the 32-bit Windows if bought separately.

On a conclusive note, I would recommend you to go for 64-bit Windows because you need to keep in mind the future scenarios for your machine. As of now, almost every computer comes with a 64-bit processor packed in. If you’re using the older 32-bit operating system, you’re wasting the computing resources you have paid for. As far as the software availability is concerned, it is not a deal-breaker, be assured there will be plenty of them.

CMD Tricks to Boost Your Internet Speed Using CMD (Command Prompt)

Today i'm going to present a blog over “How to boost your internet speed”. As we all are aware with the vast use of Internet in today’s life. But what happens when your internet speed is very low? Yes, I too well know how much I feel aggressive when my internet speed is as lower as 2G. So in order to resolve the problem of Internet speed, I am going to give you a trick to increase internet speed on Windows (7,8,8.1) by using a command prompt. So have a look on complete guide discussed below to proceed.

How to Boost Internet Speed Using Command Prompt 2016

The method is quite simple and easy and you just need to use some commands that will boost up your internet speed to some extent. So follow up some simple steps below.

Commands to Execute To Speed Up Internet Using Command Prompt:

First of all in your windows PC click on Start and Type “cmd” in Search program and files box (right click and select Run as Administrator). Now command prompt will appear and in command prompt go to root directly “C:\” by typing “cd C:\“.

Make Your Internet Connection 4G Using Command Prompt

Now you need to execute the below commands to speed up internet in your PC.

#1 Checking the Internet Speed Using Default Gateway Ping

First of all you will need to check the internet speed from the default gateway that your PC had currently connected to and for that firstly you need to find the default gateway address and then checking the connection speed at that IP address.

-> First of all find the default gateway by entering the command ipconfig /all in the command prompt. And there note down the default gateway address.

-> Now you need to ping the connection on default gateway and for that enter the command ping -t <your default gateway address>.

And with this you will see the time periods of the packet thats acknowledgement is received and lesser the time period more is the internet speed. Now our target will be to minimize this time period.

#2 Releasing The Allocated IPs

When your device has connected to the internet connection the IP address are allocated to the devices and the speed got limits to that IP connection and you can release that and can renew it by entering the command:

ipconfig /renew

#3 Flushing The DNS

In most of the operating systems and DNS clients will automatically cache IP addresses and other DNS results and this is done in order to speed up subsequent requests to the same hostname. Sometimes bad results will be cached and therefore need to be cleared from the cache in order for you to communicate with the host correctly which can lead up the slow connection, so better to flush all these DNS. In Windows OS in cmd you need to enter the below command to flush the DNS.: ipconfig/flushdns

#4 Using netsh Interface TCP command

There are two types of commands that you need to enter in your command prompt to boost up your internet speed.

“netsh interface tcp set global autotuning=disable“.

 “netsh interface tcp set heuristics disabled”

After entering these commands, you can check your default gateway speed to and also the change in the internet speed that will be quite easily visible to you.

So the above discussion is all about Best CMD Tricks to Boost Your Internet Speed Command Prompt. Make sure after using this trick must try to check you speed using some speed checker online tools. Hope you liked this article. thanks
