What is the difference between 32 bit and 64 bit CPU?
The difference between a 32 bit and 64 bit CPU is the speed in which a computer will read and process the information. A 64 bit CPU will read much quicker and can handle the memory usage better than a 32 bit.
Is an eee PC 32 or 64 bit?
Depends on CPU. Atom 230, for example, is 64-bit.
What is the difference between 32-bit and 64-bit version of windows operating system?
Basically it has to do with the size of the chunks of information handled by the CPU (the computer's processor). The 64-bit chunks are obviously twice the size of 32-bit chunks and a CPU on a 64-bit system can work faster.
Which is the fastest a 64 bit CPU 32 bit CPU 16 bit CPU?
64bit, It can use more than 3gb of ram, while 32bit can utilise only 3gb.
How wide is the data bus for a post Pentium CPU?
its 64 bit
Can a 64 bit Operating System be Installed on a 32 Bit Processor?
No, this is how it works. 64-bit CPU - 64-bit OS - 64-bit Program = Yes 64-bit CPU - 32-bit OS - 64-bit Program = No 64-bit CPU - 64-bit OS - 32-bit Program = Yes 32-bit CPU - 64-bit OS - 32-bit Program = No So, basically, the 64-bit CPU just means that it can support an OS up to 64-bits. But whatever OS you install is the deciding factor. So, a 64-bit program will not work on a 32-bit OS, even if there is a 64-bit processor, although a 32-bit program will run on a 64-bit OS.

What is the difference between 32 bit microprocessor and 64 bit microprocessor?
The fundamental difference between a 32-bit and 64-bit microprocessor is what their names suggest: the size of the basic integer operations, also called the 'native' size of a CPU's calculations. The native size of a CPU determines a whole bunch of related characteristics.For instance, all integer calculations are done using the native size; this matters in terms of performance for several reasons:if you add two integers smaller than the native size, it requires only a single operation.if you add two integers larger than the native size, you must perform 3 operations (add the upper values, add the lower values, then combine).For instance, if you wanted to add two 20-bit numbers, on both the 32-bit CPU and 64-bit CPU it would require a single operation. However, if you wanted to add two 40-bit numbers, it would require only 1 operation on a 64-bit CPU, but 3 operations on a 32-bit CPU.The native size of a CPU also determines things like the maximum addressable memory - thus, a 32-bit CPU can address up to 2^32 = 4GB of memory, while a 64-bit system can address up to 16 Exabytes. It also determines the minimum size of information that has to be processed - when fetching information from caches and memory, no operation can be done with information less than the native size. Thus, 64-bit CPUs are more demanding on memory subsystems, as they need to process information in 64-bit chunks, rather than 32-bit ones.
Difference between 32-bit and 64-bit Windows system?
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 handles large amounts of random access memory (RAM) more effectively than a 32-bit system.
What is 16 bit or 32 bit?
This refers to how the CPU processors the information, 32 bit is more current than 16 bit and much faster. 16 bit is obsolete because we not gave 64 bit systems.
CPU speed needed for Windows 7?
On there website as: 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
How many bits is the wii?
GameCube is NOT 128-bit, and Wii is NOT 256-bit. 360 is NOT 360-bit. Nintendo 64's CPU is a derivative of the 64-bit MIPS Technologies R4300i (which is where the rabbits in Super Mario 64 got their name, MIPS) -- i.e. uses a 64-bit CPU GameCube's CPU is 64-bit (thus making the GameCube a 64-bit console) The Wii's CPU is also 64-bit. I.e. the Nintendo 64, GameCube and Wii are all "64-bit". The Xbox is also 64-bit As is the PlayStation 2. The PlayStation 3 has a CPU with a single word size of 32-bit. Xbox360's CPU has a 256-bit bus. To be really honest, I have no idea what I'm talking about. But it's not simple to simply say "The GameCube is a 128-bit console". Because "OMG it haz betar grafix" does NOT mean it has "more bits".
What are the disadvantages of a 64-bit processor versus a 32-bit processor?
There aren't any real disadvantages to 64-bit processors. When running a 64-bit operating system, running a 16-bit application requires a context switch from 64-bit to 32-bit, from 32-bit down to 16-bit, and back to 32-bit and 64-bit. This creates a large performance penalty so in practice most 64-bit operating systems will not allow you to run 16-bit applications. This is unlikely to be a problem for most users, though. There is one significant disadvantage of 64-bit processors when compared to 32-bit processors: minimum operation size for calculations. A 64-bit processor must do all integer calculations using a 64-bit wide register (that is, all integers must be represented as 64 bits in size). A 32-bit processor does all integer calculations in 32-bit sizes. While performing the actual calculation (e.g. adding two numbers) is neither faster nor slower under 64 vs 32 bit systems, the requirement to pull full 64-bit chunks from memory to do any calculation results in more memory "pressure" than a 32-bit processor. The result of this is that for a system which does mostly smaller integer calculations (i.e integers which are 231 or small in size), a 32-bit system will have about HALF the memory bandwidth requirement of a 64-bit system. A memory latency is the the dominating factor in modern CPU performance (i.e. the time to get data from memory is far greater than the time to perform a calculation on that data), a 32-bit processor will perform noticeably faster doing such smaller calculations than a 64-bit processor. A related disadvantage of a 64-bit CPU vs a 32-bit CPU is that the larger operational unit (word) size means that all pathways, registers, and memory units attached to a 64-bit CPU have to be about double the size as required in a 32-bit CPU. This results in about a 40% larger number of transistors required to implement a (roughly) equivalent 64-bit processor vs a 32-bit processor. This does not translate into a 40% higher cost, but does significantly increase production costs; it also significantly increases the thermal profile of the processor (i.e the larger number of transistors requires more power and produces more heat).
