64bit, It can use more than 3gb of ram, while 32bit can utilise only 3gb.
This refers to how the CPU processors the information, 32 bit is more current than 16 bit and much faster. 16 bit is obsolete because we not gave 64 bit systems.
Most operating systems are designed for either 32-bit or 64bit CPU's.
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.
Basically, the difference lies in the way the program process information : 2 bytes at a time for 16 bits, 4 for 32 bits. Older system usually use a 16 bits processor (often with a 32 bits "virtual" capacity), while newer system all use 32 bits processors that can input 4 bytes of information per clock beat for processing. During a single cycle of the CPU processor, a 16-bit program can send 16 bits of instructions to the CPU. A 32-bit program can send twice as many (32 bits) of instructions during a single cycle. Therefore, 32-bit programs are often able to run faster than 16-bit programs but because the speed of a program is effected by so many other factors, a 32-bit program is unlikely to be twice as fast as a 16-bit program

32 bit drivers are designed for 32 bit computers. 16 bit drivers are designed for 16 bit computers. Most modern computers are either 32 or 64 bit.
Depends on CPU. Atom 230, for example, is 64-bit.
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.
The number of bits a CPU uses to represent integer numbers (as opposed to floating point numbers or memory addresses) is often called "register width", "word size", "bit width", "data path width", or "integer precision". This number is often considered one of the most important characteristics of a CPU. Most CPUs are 8 bit CPUs. An 8 bit CPU -- i.e., a CPU where each register holds 8 bits -- typically has a 8 bit data bus and a 16 bit address bus. One of the first 32 bit CPUs -- the MC68008 -- had registers that held 32 bits, a 20 bit address bus, and an 8 bit data bus. Some popular 32 bit CPUs -- i.e., CPUs with registers that hold 32 bits -- had a 32 bit data bus and a 24 bit address bus.
Assuming you are running a 32 bit (modern) operating system, 32.
