What is the primary advantage of a 64-bit operating system versus 32-bit?

A 64-bit OS (in concert with a 64-bit processor) will be able to run 64-bit applications (applications written to take advantage of 64-bit OS's & CPU's)
The catch is, there arent any 64-bit applications on the market as yet, so you arent likely to see any advantage until such time as one is released.
Having a 64-bit OS would also mean you would be able to fit up to 16GB RAM memory that would be recognized by Windows XP/Vista.
By far the greatest potential advantage of a 64 bit OS is the vastly increased virtual address space. In 32 bit Windows all processes have a private 2GB virtual address space. This is totally independent of RAM size. In 64 bit Windows, when running native 64 bit applications, this address space increases to 8192GB, again totally independent of RAM size. For applications using large databases, video editing, etc., this is a MAJOR advantage, even if you have only 4GB RAM.
Another advantage is the ability access more RAM. In some server editions this may be as high as 2048GB. That is larger than what is currently commercially available.

To fully utilise the 64 bit data bus the programs must be written in such a way that they can use 64 bit wide data bus. A 64 bit processor can also act as 32 bit.

-Up to 64 CPU's in servers
-High speed architecture

Are they any differences between setting up a wireless router on Windows XP versus Windows Vista?
Normally, no. The router setup is usually contained within the device itself, so the operating system should not change anything.
When using large mode to access a hard drive how is the 504 528 MB barrier broken?
LBA (logical block addressing) is a function of the drive electronics but can also be a weakness i the operating system (Win 3.1 versus Windows XP for example.)

What advantages does cartridge fuse has over rewireable fuse?
Answer 1 - Advantage of Cartridge Fuse versus "Inline" FuseThe only advantage I'm aware of is that it is much easier to remove to examine for condition, and thus easier to change/replace.
What is the advantage of the metric system of units over the british system?
The metric system is based on multiples of 10, and human math tends to work well with multiples of 10. Just think how easy it is to do 8 x 100 in your head, versus 8 x 193.This means you don't have to remember that there are 12 inches in a foot, or 5280 feet in a Also, water freezes at 0 and boils at 100. I have no idea how anyone developed a system where this is not the case.

What is discussed most when debating Linux versus Windows?
When debating Linux versus Windows, it has been debated that Linux is an out outdated system and is not user friendly. Conversely Windows conversely has had the label of slowing down the entire system and is intended simply for single user.
