Tell me friends
Difference between x86 and x64 architecture

Ones 32bit and the other isn't. That's the only difference

The "bit", refers to the width of the register. A 64-bit register can hold more data than a 32-bit register, and, subsequently, which in turn holds more than 16-bit and 8-bit registers. The more ample the space in the CPU’s register system, the more it can handle—especially in terms of using system memory efficiently, and so run faster.
One important factor which came up when programmers began to make more memory intensive applications (Apps), was that a computer with 8 GB of RAM was considerably more responsive than one with 4 GB of RAM. 32-bit PCs were limited to 4 GB of RAM. 64Bit were not.
There are more technical considerations, but for the avergae user, that is enough to know.

As others have eluded too, the main difference is addressable memory. In 32 bit OSes you have access to 4GB of physical memory (2^32bits) although applications actually deal with virtual memory which the memory manager in the kernel handles. In 64bit versions you have access theoretically to 16 exabytes although Microsoft imposes limits based on the edition you are using. Another more obscure difference is how exception handling is done in 64 applications. There are other differences but for the most part only developers are concerned with them and they are totally unnoticeable to end users.

Ok it is enough for me ...................
