Ext2 is a file system for the Linux operating system, developed in 1993. It stands for "Second Extended File System" and was designed to improve upon the original Ext file system. Ext2 supports large file sizes and partitions, making it suitable for various applications, from personal computers to servers. One of the key features of Ext2 is its simplicity and reliability. It does not include a journaling feature, which means it does not keep a log of changes, making it faster in some scenarios. However, this also means that it is more vulnerable to data loss in case of a system crash compared to newer file systems like Ext3 or Ext4.
