    Thanks to all who consider my question

    16 bit and 32 bit applications are still used in industry control systems
  3.  
    Basically, it refers to the number of addressable memory locations. 32bit doubles the number of addressable memory locations over 16bit and 64bit doubles that of 32bit. The more addressable memory locations you have, the more complex your applications can be which can have a direct correlation to capability and performance. Think of the 32bit or 64bit architecture similar to that of a post office, and the memory locations in that post office are the pigeon-hole boxes where the mail is placed. Instead of mail, you store bits of data. Those bits of data can be referenced and manipulated.

    64bit systems because of the additional number of registers, (special pigeon holes), memory locations where arithmetic calculations can be performed, are generally faster than 32bit processors. 64bit processors can usually process more instructions per second (MIPS) than 32bit systems. However, the proficiency of any architecture is including 64bit is dependent on the developers that may or may not use the additional registers. This could explain why performance of 64bit applications may not dramatically improve over 32bit apps, because one of the concerns the developers have during this development is of "backward compatibility", i.e., that it will work on 32bit systems too. Over time, with more end-users such as yourself, investing in 64bit systems, this concern will and has become less important. Just like 8bit or 16bit programs are rarely encountered and/or used these days, 32bit apps will eventually share the same fate.

    For a more complete and technical explanation refer to this article but keep in mind that it was written in 2005. So, it is written when 64bit processors had not fully established themselves in the market.

    All you really need to know is... 

    1. 16bit software is obsolete (Gone) 
    2. 32 bit is on it's way out but is most commonly used at the moment 
    3. 64bit is taking over, but not compatable with everything yet although getting there. Also if you are using lage amounts of ram, anything over 3 gig, you need 64bit OS to take advantage of it. It's a waste with 32bit OS. 

    In Finishing 64bit software is taking over and all processors are now 64bit. 

    Oh I guess I should also mention, you need a 64bit processor to run a 64 bit OS. You need a 64bit OS to run 64bit Software. 

    To go into anymore than that will just confuse you.

    Vista Ultimate 64bit FTW.
