Peek into the Linux File System

When we try to install Linux you will see that Linux offers many file systems like these:
Ext, Ext2, Ext3, Ext4, JFS, XFS, btrfs and swap
So what are these file systems that Linux offers?
Ext: an old one and no longer used due to limitations.
Ext2: first Linux file system that allows 2 terabytes of data allowed.
Ext3: came from Ext2, but with upgrades and backward compatibility.
The only problem about it that the servers don’t use this kind of file system because this file system doesn’t support file recovery or disk snapshots.
Ext4: faster and allow large files with significant speed.
JFS: old file system made by IBM. It works very well with small and big files, but it failed and files corrupted after long time use, reports say.
XFS: old file system and works slowly with small files.
Btrfs: made by Oracle. It is not stable as Ext in some distros, but you can say that it is a replacement for it if you have to. It has a good performance.
