Explain file system in unix.
Answer / Dhanesh Kumar Pandey
A file system is a way of organizing, storing, and retrieving files on a storage device. In Unix, the file system is hierarchical, which means it consists of directories (folders) and files arranged in a tree-like structure, with the root directory (/) at the top. Each file and directory has permissions controlling access to them, ownership information (user and group), and metadata like creation and modification times. Unix uses various file systems like ext2, ext3, ext4, and FAT.
