64-bit operating system?

Question

What is it and what is the differenceb/w the 64 bit and the 32 bit and how does it affect your notebook?

Answer 1

64-bit are processors of x64 architecture and 32-bit processors of x86 architecture, 64-bit is supposed to be faster, the problem is the compatibility: Is not very easy to get drivers for 64-bit. Most computers are 32-bit so If you are going to buy a notebook you the extra expense is not worth it.

hope it helps!

Answer 2

So the 64 bit OS is designed to work on a processor with a 64 bit wide address/IO bus, where as the 32 bit OS is designed to work on a processor with a 32 bit wide bus. In the windows world you can usually run the 32 bit OS on a 64 bit machine but not the other way around..All things being equal the 64 bit machines will process twice as much address and I/O data as a 32 bit machine and hence are considered faster ..

And may be if your application is not I/O bound at a peripheral device..

Answer 3

for starters: it doesn't run on my notebook, since I don't have one :)
A 64 bit operating system isn't twice as fast as a 32 bit operating system, only in theory it is. It has to do with the way the Central Processing Unit (CPU, or the processor) can handle assignments. You do need a 64 bit-capable CPU for a 64 bit operating system. And (as long as it wasn't written by a company in Redmond) it is as stable as any 32 bit operating system. But not too many programs for Windows are 64 bit-capable, though the number is growing fast.

Answer 4

64 bit OS's are 2x faster than 32 bit, but 64 bit is currently less stable than 32 bit (not by much.) If you install a 64 bit OS then you need a 64 bit capable processor.

Answer 5

... the main drawback to the 64bit OS is lack of driver and software support at this time ...
