64-bit refers to a processor with registers that store 64-bit numbers. A generalization would be to suggest that 64-bit architecture would double the amount of data a CPU can process per clock cycle. Users would note a performance increase because a 64-bit CPU can handle more memory and larger files. One of the most attractive features of 64-bit processors is the amount of memory the system can support. 64-bit architecture will allow systems to address up to 1 terabyte (1000GB) of memory
It isn't an issue of advantages, it is an issue of compatibility with your computer. The 64 bit operating system can take full advantage of the capabilities of a 64 bit microprocessor, if your computer has a 64 bit microprocessor. However a 64 bit operating system will not run at all if your computer has an older 32 bit microprocessor; you will have to use a 32 bit operating system on that computer.
They are both the same

No.
An operating system is made up of many pieces of code, sometimes "bugs" or errors are found to exist in bits of this code. Once these have been found, they are then corrected and a replacement for the code is sent out "as a patch" to people who have the operating system installed.
Windows 7 (64-bit), Ubuntu, and I Think Macs
Most modern UNIX systems run as a 64-bit Operating System.
In a 64-bit system, there are 8 bits in a byte.
I think 32 bits but it really doesn't matter because I heard the ps3 has a 32 bit operating system and the wii has a 32/64 bit so bits have no meaning anymore
A 264-bit system has 64 bits.
It's compatible with Windows XP SP3 (32 bits) and operating systems of 64 bits like Windows XP Pro x64 or Windows Server 2003/2003 R2 are not supported.
The storage capacity of a register is determined by the architecture. Thus they are 32 bits long on a 32-bit system and 64 bits long on a 64-bit system.

A 16 bit computer is one where the internal registers in the computer's CPU are made from 16 wires in parallel. Computer registers, in the main, started with 8bits, grew to 16 bits, then to 32 bits and now are mainly 64 bits wide. You need an operating system 'made' for each 'bit' size. For instance Microsoft's Windows 7 operating system is currently available in both 32 and 64 bit versions. The more the bits available the larger the value of an integer number that can be processed by the CUP in a single clock cycle.
a bit is the amount of information in a system having two equiprobable states. There are 8 bits in a byte. So a 64 bit would be a better operating system because bit is a measurement of information. Depending on what you want your operating system to do a 32 bit is an average computer but if you will probably have tons of files and downloads or installations then if you really want to spend more money then go for a 64 bit but a 32 bit is a good computer also.
A 64-bit operating system can directly address more memory. This makes it "better" if you have more memory than can be addressed in 32 bits ... 4 GB. If you have 4 GB of RAM or less, there's essentially no difference, and the 32 bit system may even be slightly faster.
