None. It is possible to operate Linux without a swap file or 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.
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
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
There's no precise limit; it depends on the architecture of the machine. On 32-bit Intel machines, the limit is 2 GB per partition, though there is no limit on the number of swap partitions.
Swap partition
It uses the swap. The swap is a dedicated partition and not a file.
You do not need to set up a dedicated partition for swap as you can also set up a swap file.
He did the minimum amount of work possible.Most people want the minimum amount of yard work possible.
virtually all linux distros are free, excluding internet use and man hours to get it going.
This is entirely up to whoever sets it up, but the rule of thumb is usually 1.5x the amount of physical system memory on the machine. For example: If you have 2 GiB of RAM, then it's considered good practice to create a swap partition of size 3 GiB. However, Linux's memory management is much more effective and efficient than Windows, and when you have 2 GiB or more of RAM it's considered optional to set up or use swap space, as your system has plenty of memory in which to work. If you have 4 GiB it may be considered wasteful to create any swap space at all unless your computing needs are very memory-intensive.
Minimum is the amount you need just to use it. Recommended is the amount it is advised you have for best performance.
