ext2 (second extended filesystem)
ext2, or second extended filesystem, is a type of file system used in Linux operating systems to organize and manage data on storage devices like hard drives. It structures data efficiently, allowing files and directories to be stored, retrieved, and modified reliably. ext2 was popular for years due to its stability and simplicity before newer systems with additional features appeared. It supports large files and partitions, providing good performance and data integrity. While it lacks some modern features like journaling (which helps recover data after crashes), it remains a foundational, straightforward filesystem known for its robustness.
