Post Lab Questions (1.2)
	1)IP addresses and phone numbers are similar in that they both are comprised of numbers and direct you
	  another location (another website or another person's home phone).
		-Pathnames and URLs are similar in that they both specify the location of a file on a particular server.
                -URLs are visually different because the file names are specified with ://
		-FTP is perferab;e when it comes to privacy because it requires a username and password. However, in terms 
                 of convience, HTTP is preferable because you do not have to type a username or password everytime you send 
                 a file.  
		-It is not correct to say that folders/directories directly contain data becuase you have to send a request 
 		 into the server,which, in turn, sends a copy of the file which you are requesting.
