1. Windows computers use drive letters to uniquely identify the partitions available to users. A single drive with two partitions may have those partitions marked as "Drive C:" and "Drive D:". Unix does not use drive letters, but instead attaches all partitions to one 'root' directory structure. Give one benefit of each of the two different methods. 2. Since unix filesystems all attach together into the one root filesystem it isn't obvious where one filesystem ends and where another begins. From the lesson, what commands can be useful in determining where one filesystem ends and another begins? Why is that command useful? (What does the output tell you?) 3. You have seen how absolute and relative paths can be used to navigate inside the root filesystem. Can relative paths be used to navigate down (deeper into) an existing filesystem? Choose a side of the argument and provide an example that illustrates your point
