Usually, the only reason for /swap to be used on a system is when your system's resources (RAM) are used up by running applications. If /swap is constantly being accessed on your Linux system, you might want to consider adding some more RAM to your computer.
That is the "swap partition." It is a dedicated space on the hard disk that fulfills the "swap" feature of virtual memory in Linux.
None. It is possible to operate Linux without a swap file or partition.
If you have plenty of RAM: 1, as a swap partition is rarely used by Linux on systems with more than 2 or 3 GiB of RAM available, and all the toplevels of the Linux directory structure can be put on the same partition. A swap partition on a system with plenty of RAM is a waste of hard disk space. If you're strapped for memory, 2, to allow for the swap partition, so that Linux can extend its memory onto the hard disk so you won't run out. A good rule of thumb is to create a swap partition at LEAST 1.5 times larger than your system RAM. For example, if you have 512 MiB of RAM: a 768 MiB MINIMUM swap partition is advised. If you have lots of hard disk space, an ideal consideration is actually to triple your RAM in swap space: 512 MiB of RAM will be supported by a 1.5 GiB swap partition. Personally, if you have lots of hard disk space, I recommend at least 3: One for /, one for /home, and one for swap, if needed, otherwise it'll be for /boot.
82 => Linux swap / Solaris 83 => Linux ext2 & ext3 85 => Linux Extended partition
Linux uses a swap partition, a piece of the hard disk itself set aside by the system for receiving page-swapping. However, if you have more than 2-3 GiB of RAM on your desktop, you probably want need to make use of virtual memory at all in Linux.
A swap partiton because it is a dedicated partition and not a file
Install Vista first. During the installation of OpenSUSE, you will be prompted if you would like to partition the hard drive to make room for OpenSUSE, or format the drive entirely for OpenSUSE. Make a partition of at least 6 GB, plus a swap partition of 1 GB. The installer will automatically install a bootloader known as GRUB, which can boot Vista or OpenSUSE at your choosing.
Swap
True.
Linux swap partition has the code 82 (hex). A swap partition must be formatted with mkswap before first use. You can use swapon and swapoff utilities to enable/disable swap
82
It's called virtual memory. The space itself is called the pagefile (Windows) or swap area (Linux).
