Linux supports a wide range of file systems. Distinguish the three Extended File Systems of Linux.?

What will be an ideal response?

Linux supports a wide range of ?le systems. The early standard was Second Extended File System (Ext2), and then Third Extended File System (Ext3) replaced Ext2 in most Linux dis- tributions. Its major difference from Ext2 was being a journaling ?le system, which has a built-in ?le recovery mechanism used after a crash.A few years later, Fourth Extended File System (Ext4) was introduced. Among other features, it added support for partitions larger than 16 TB, improved management of large ?les, and offered a more ?exible approach to adding ?le system features. Because these changes affected the way the Linux kernel interacts with the ?le system, adoption of Ext4 was slower in some Linux distributions, but it's now considered the standard ?le system for most distri- butions. The Ubuntu version you used previously, for example, has an Ext4 partition at its core, unless you select another ?le system during installation.  ??
