1. Describe at least one way in which IP addresses and phone numbers are similar.
Both phone numbers and IP addresses are composed of groupings of numbers set in 
an organized, hierarchical fashion, which correspond to specific accounts (ie: a 
specific computer or telephone).

2. HTTP and FTP are both standard ways of sending/receiving files
through a network. How do they compare with respect to privacy?
How do they compare with respect to convenience?
FTP is more secure because it requires a user to log in with a user name and 
password.  HTTP is more convenient because it does not require a person to 
identify himself or herself every time a link is clicked.

3. Is it correct to say that folders/directories directly contain data? Why
or why not?
No; they merely contain directions by which to access certain pieces of data.

4. Recall pathnames from the last lab. Discuss at least one way in
which pathnames and URLs are similar.
Both are used to specify the location of a certain file, with the folder names 
being separated with slashes.

5. How can you recognize whether something is a pathname or a URL?
(I.e., what is visibly different about them?)
A URL will specify the host computer which contains the file.  This appears 
between the :// and the next /.
