The directory path has two absolute and relative paths
An absolute path defines the exact location of the directory in the virtual directory structure, starting at the root of the virtual directory, equivalent to the full name of the directory
Absolute paths always start with a forward slash (/)
Example:/usr/bin
Using an absolute path can clearly indicate exactly where the user wants to switch to. To switch to a specific location in the file system with an absolute file path
Cd/usr/bin
Relative paths allow the user to specify a destination file path based on the current location.
directories accessed by the user can be accessed directly from the directory name in the current directory
