You do not need to set up a dedicated partition for swap as you can also set up a swap file.
A swap partiton because it is a dedicated partition and not a file
It uses the swap. The swap is a dedicated partition and not a file.
the sign for root partition in linux is : /
82 => Linux swap / Solaris 83 => Linux ext2 & ext3 85 => Linux Extended partition
That is the "swap partition." It is a dedicated space on the hard disk that fulfills the "swap" feature of virtual memory in Linux.
Your question does not make sense. But anyway, virtual memory is basically using harddrive space as fake memory larger than ram. Linux have option to place it on separate partition for efficiency. If you let it use a file, double management of file and virtual memory must be managed.

Linux will not delete a partition unless you tell it to. If you have accidentally deleted a partition, but have not written to the disk, you may be able to restore most or all of the data that was on it. The program "testdisk", found on many Linux LiveCDs and partition editors, can restore the deleted partition flags.

Yes. To achieve this, you need to shrink the window partition so there is space for the Linux partition on the disk.
