How would you explain unix system directory?
The Unix system directory is a hierarchical file system that organizes files and directories in a tree-like structure. The root directory, represented by "/", is the topmost level, from which all other directories branch out, such as "/bin" for essential programs, "/etc" for configuration files, and "/home" for user directories. This organization allows for efficient file management and access, with each directory potentially containing subdirectories and files. Overall, it provides a systematic way to navigate and manage the system's resources.

How does unix access a file from a directory?
Unix accesses a file from a directory using a hierarchical file system structure. When a command is executed to access a file, the Unix kernel navigates through the directory tree, starting from the root directory, to locate the specified path. Each directory contains entries that map file names to their corresponding inode numbers, which store metadata and point to the actual data blocks on disk. By reading the inode, Unix can access the file's content efficiently.
