meaning that when you execute the program, it runs as though the file owner is the user instead of you. Many programs use this setuid bit to run as root in order to get the privileges they need to change system files. One example is the passwd...

Relative path– indicates the target file based on the current directory. This method is helpful if the directory structure is unlikely to change. For instance, if you’re in the/home/user/documents/directory and want to link tomyfile.txt, type: ...
