What is the difference between Soft link and Hard link in Unix?

A soft link is a pointer to a file, directory or a program located in a different location. A hard link can point to a program or a file but not to a directory.

We use the command ln –s for creating a soft link. But a hard link can be created by ln command without –s option.
