+        This part of the book describes different configuration you
+        can set on in order to connect computers phisically. The main
+        purpose of connecting computers this way is to make Internet
+        Protocol (IP) available over the link. This is the first step
+        we need too achieve in order to exchange data from one
+        computer to another using Internet services.
