If someone be so kind as to explain the difference between 64-bit, 32-bit, etc. applications/os's/ systems and related stuff.

What exactly does it mean to use a 32-bit or 64-bit application or software/hardware why is 64-bit better?

Please explain.

Thanks.
 
Well for one, 32-bit supports up to 4GB memory, no matter what MoBo you have. With 64-bit architecture, you can have up to 16GB memory, whether MoBo or server. Also for paging file sizes, usual on 32-bit is 16 TeraByte (TB), while 64-bit is 512 TeraByte's.

64-bit overall alows smoother data rates, data transfer speeds, faster load times, and generally a faster gaming/business/home machine. 64-bit is coming out very soon, and will be used with Windows XP Professional mainly.
 
the 32 and 64 bits correspond to the width of the data bus
1 byte=8 bits

32 bit bus can move 4 bytes at once
64 bit bus can move 8 bytes at once
by making the data bus bigger or wider the CPU can move bigger chunks of data per clock cycle and thus do more work in less time


someone above mentioned memory addressing, the address bus is separate and CPU's havent been "square" for a long time(address bus size=data bus size)

just for perspective:the nintendo orginal was 8 bit data bus and 16 bit address and video bus

when x86 PC's hit the market they had a 16bit data bus,and shortly after that the 32 bit machines came along, but they often had 32 bit data buses and bigger address buses, some of the latest 32 bit CPU's have 40+ bit address buses so they can address memory ranges bigger than (2^32)

At any rate, the bit number corresponds to the data bus width, the address bus is separate and varies in size

As far as 64 bit software, there isnt any,nothing really mainstream anyway,probably be 2-3 years before actual real 64 bit apps are commonplace.

Damn yer smart.. thanks man.

That's what I was looking for.. makes much more sense now.

:D
