Answer 1

An Absolute Path is the location of a file or directory from the root directory(/). In other words we can say absolute path is a complete path from start of actual filesystem which is the / directory.

$HOME is an environment variable which stores the location(absolute) of the user's home directory.

So, if my user name is user1, $HOME will generally contain /home/user1.

If I'm root $HOME will contain /root.

Now, if you are a normal user and user name is, let's say, user1.

The absolute path for Your_Name_goes_here.dat will be:-

         $HOME/Project4/Sales/RegionB/Your_Name_goes_here.dat

which is equivalent to

        /home/user1/Project4/Sales/RegionB/Your_Name_goes_here.dat

The absolute path for Sales will be:-

       $HOME/Project4/Sales/

or

      /home/user1/Project4/Sales/

On the other hand, Relative Path is defined as path related to the present working directory(pwd).

Since your current directory is RegionA, the relative pathname for the following files and directories is:

West1.dat

     ../RegionB/West1.dat

.. is here for 1 directory upwards

RegionB

     ../RegionB
