Swap Space, in Linux, is a Virtual Memory mechanism.[1]

If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the Swap Space.

Swap Space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM.

Swap Space is located on hard drives, which have a slower access time than physical memory.

Swap Space can be a dedicated swap partition (recommended), a swap file, or a combination of swap partitions and swap files.

Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB.
