Default Swap Partition? Why?
Why do we need swap space? What is it used for?

It is used as memory, the same as RAM. Only it is slower so the OS moves memory storage to it that isn't used frequently or fast.

It is to add more memory to your machine. Even Windows has it although it is a swap file and much slower. Using a swap file you can't defrag your entire partition.

Isn't it also used for dual-booting operating systems? I think I've heard of this term when a friend of mine used Windows Vista and dual-booted Ubuntu Linux on his machine.

Well it is not used for dual booting, even if you install Ubuntu alone on a machine as far as I know it will still need a SWAP partition.

So the bigger the SWAP partition the better the performance?

And why is a swap file slower than a swap partition?

I think that depends from the kernel, but I think that a swap partition or a swap file is always required, but it seems like linux uses swap partition not files.

What's the difference, in terms of performance, between a swap partition and a swap file? Why would a partition be faster than a file?
