Differance B/W 32 Bit & 64 Bit:
The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information.
The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

Today’s PCs come in two varieties: those running a 32-bit operating system and those running a 64-bit operating system. The difference is the amount of information the PC’s processor can handle at any precise moment. While a computer designed for a 64-bit operating system has vastly more potential computing power, it requires fundamental changes to the way its software is designed.
The word "bit" refers to the way computers deal with information in binary, where all data is listed as a string of digits which can either be a 0 or a 1. Each of these digits is known as one bit, meaning a 32-bit processor can process 32 digits at once. Don’t confuse this with memory, which measures the total amount of information a computer can remember without needing to use a storage device such as a disk. While the figure for memory will be much bigger, a computer can’t process all of that information at once.
The software for a computer with a 32-bit processor, including operating systems such as Windows, has to be specifically written to match that processor. The same applies to 64-bit processors. Microsoft produced 32-bit and 64-bit editions of Windows XP and Vista, and will do the same for Windows 7.
There are also some significant mathematical limits to the two different types of processor. A 32-bit processor can only work with a maximum of 4GB of memory, and this is usually limited to 2GB for any one program. A 64-bit processor could theoretically work with 17 billion GB of memory. A 64-bit processor can also carry out some tasks twice as quickly.
The memory limitations of a 32-bit processor started to become clear with Vista, which uses a large amount of memory and can make it difficult to run multiple programs at once without using up even a full 4GB of memory. Meanwhile, it once seemed impossible that any one program would need more than 2GB of memory, but some modern video games have hit that limit. For these reasons, 64-bit processors will likely start to become much more popular, which will increase the number of consumers interested in buying a 64-bit operating system.
A 32 bit processor is faster than a 64 bit processor, 64 bit processors are very commonly used that you can find it easily in any home pc but the main difference is the hardware you are having on your machine. For 32 bits there isn't any need of any wide main bus to carry 32 bits at a time but for 64 bits its must that you should have a wider bus to carry 64bits.
The main difference between a 32 bit and 64 is that 32 bit system has 4gb(gigabytes) of space for addressing means that the 32 bit system has a limit of 4GB RAM to process data where as the 64 bit operating system has 2^64 bits of space to address and supports 16 hexabytes of RAM to process data.
In simple words an operating system of 32 bit has a 4GB limit to process any data depending upon the sizes of files and RAM
A person who does not care about the category will find 64 bit more beneficial than 32 bit because he can use 64 bit OS with 32 bit OS and software. If we compare 64 bit with 32 bit OS, 64 bit is faster and performs more upgraded silicon processes and have more no of transistors which proves it to be more advantageous than 32 bit.
Now most of the software companies are developing their software in accordance to the 64 bit environment, it's really hard for the consumers to run a 64 bit application in 32 bit environment, in this case they have to upgrade their hardware's such as RAM which is also a big issue because most of the computer users have less than 1Gb in their systems.
So instead of changing your hardware often I would recommend 32 bit OS over 64 bit which is more user friendly and enables its user to run applications of 64 bit in 32 bit environment.
