Its all about the ability of any operating system to hold the maximum size of memory. 

 

Thirty Two Bit Operating Systems

It can handle maximum 2's power Thirty Two, maximum size of memory (RAM) can be handled by this operating system is Four Gigabyte (GB). 

 

Sixty Four Bit Operating Systems

It can handle maximum 2's power Sixty Four, maximum size of memory (RAM) can be handled by this operating system is Sixteen Exabyte (EB). 

 

Note: I have used alphabet to represent the numeric values e.g. Thirty Two, because of the automatic filtering system on Bayt.com is not accepting of any numeric value, I hope you understand.

A computer's CPU (central "processing" unit) capacity to "process" information.-bit has a higher capability than that of the-bit and-bit is not reverse-compatible with previous-bit versions (prior).

A-bit OS can support memory upto4 Giga-byte, therefore it is mostly used with Desktop PCs.

A-bit OS can support memory upto Exa-byte, therefore it is mostly used with Servers.

However, due to reduction in hardware costs, many desktop and laptop systems are also shipped with more than4 GB Ram, thus required anbit OS.

If you are an IT person then you must have heard about assembly language. A bit OS contains instruction consist of bits instructions on each memory block while on bit instructions are saved on bit block.If you a non IT person, Then you can consider a narrow path and a wide path, Where a path will allow some instructions to pass and vice versa.

The terms-bit and-bit refer to the way a computer's processor (CPU), handles the information. The-bit version of operating system handles large amounts of RAM more effectively than a-bit system. 

On a-bit operating system, you are restricted to a maximum of4 gigabytes of RAM

The-bit system is usually SLOWER than-bit system, because every instruction and every piece of data has to be loaded in a larger chunk, and access to RAM is a bottleneck. The-bit system will be faster only when large amounts of consecutive data need to be read, such as in heavy graphics applications, video editing etc. The main advantage of-bit over-bit is the ability to address as much memory as you have. Which system you should use therefore depends on your intended use, and I believe many users will be better off with-bit system.

8 bits =1 byte, one byte mean one charactor i.e. A,b..z, and special characters, so bits mean four characters can be proceed at a time. In other hand-bits mean eight characters can be processed at once so it would be more faster then-bits operation.

Whether shopping for a new computer or upgrading an old one, you’ve likely come across the the “-bit” designation and wondered what it meant. Read on as we explain what Windows-bit is and why you’d want a piece of that-bit pie.

Windows7 and8 have done an enormous amount to increase the popularity of-bit computing among home users but many people are unclear on what exactly it means (and may not even realize they’re already running it). Today we’re taking a look at the history of-bit and-bit computing, whether or not your computer can handle it, and the benefits and shortcomings of using a-bit Windows environment.

General rule, if you have under4 GB of RAM in your computer, you don’t need a-bit CPU, but if you have4 GB or more.

 

Software and Driver:

All Software and Driver with high performance already take advantage of the increase in available memory, so it may be used operating system bit

More the bits more fast processing so bit will be more faster and it is double of bit.

The key difference- the terms-bit &bit refer to the way a computer's processor CPU, handles information. the-bit version of windo handles large amount of random access memory  RAM more effective then a-bit system.
