In the normal sense of a "file"system, swap is not formatted as a file system.
It is formatted similar to memory or RAM.
No
The standard mount point for a swap partition is not defined in the same way as for file systems, as swap space is not mounted like a traditional filesystem. Instead, it is designated for use by the operating system to manage memory. Typically, swap is configured during system setup by specifying the swap partition in the system's configuration files, such as /etc/fstab in Linux, but it does not have a traditional mount point like /mnt or /media.
The only one I can think of is the swap partition, seeing as how it's not even a filesystem, just a place to dump pages. However, I'm sure there's even a filesystem driver somewhere for it.
A swap partiton because it is a dedicated partition and not a file
82
A swap partition is used when the amount of RAM in a computer is already full. But this is not a recommended alternative to RAM space because it has slower access time.
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
mkfs -t ext4 /dev/
The command is mkfs. Though usually most people will use: mkfs.<filesystem type> /dev/sdXY Where X is the drive and Y is the partition. For example: mkfs.ext4 /dev/sda3 means "Create an ext4 filesystem on the third partition of the first drive."
You need root privileges, and it's often best not to use fsck on a live (mounted.) filesystem. Also you'll need to know the device file and, in some cases, the filesystem of the partition you're working on. The command is thusly: # fsck /dev/sdXY In most cases the fsck command will figure out what the filesystem is and run the appropriate filesystem checker.
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.
