14. Fill in the blanks with the following terms (some of the term will not be used):
a network, an extranet, a gateway, an inter-network, a firewall, an intranet, a router
network is two or more connected computers.
inter-network is two or more connected networks.
intranet is a network contained within an organization.
firewall is a collection of programs and hardware that filters incoming and outgoing
Internet traffic
extranet is network that allows access to the Internet.
15. Is the World Wide Web a subset of the Internet (circle one)?
TRUE or FALSE

(circle all that apply)
FTP
TCP/IP
Search Engine
Web Page
Email Address

TCP/IP and Packet Switching are the core characteristics of the Internet. Network Router
is hardware that makes it work.
17. Which of the following are more closely associated with the WWW rather than the Internet?
IP Address
URL
Telnet/SSH
Ethernet Card
Web Browser
Wireless Access Point
CAT-5 Cable
HTML Documents

The circled items are definitely part of the WWW more than the Internet. IP Addresses is
debatable.
18. What was the name or abbreviation of the Military Agency
DARPA
that created the original infrastructure of the Internet?
60’s
19. In what decade was the Internet born, i.e., computers
became seamlessly connected across the USA?
Page 4 of 9
20. In what decade did the entire Internet switch to
80’s
a common standardized protocol?
didn’t be come the standard until the 80’s
21. From question 20, what was the name (abbreviation)
of the standardize protocol?
TCP/IP
invented in the 70’s
22. Who invented HTML? (circle one)
(a) Vinton Cerf
(d) nobody
(b) Paul Barans
(e) Group of 12 MIT students
(c) Ada Lovelace
(f) None of the above
23. Approximately how many servers/hosts are currently connected to the Internet?
(a) 30,000
(d) 30,000,000
(b) 300,000
(e) 300,000,000
(c) 3,000,00
(f) 3,000,000,000
24. List 5 separate things that you would need to host your own website with your own URL,
i.e., www.myname.com.
1. Computer (with static IP address) or access to one
2. Internet Access for your computer
3. Web server software
4. Registration for your domain name
5. Web pages (or software to create web pages is acceptable)
25. From question #25, which one of the things could cost the most to obtain/maintain? Explain
your answer in detail.
The computer could be costly, but if you had enough traffic to justify a fast server than you
are probably going to need to spend even more on a good internet connection ($200/month
or more). Over time, this will likely be more costly than buying, maintaining, and
upgrading your server. But a computer could be the most costly expense, so it is
acceptable. Also, web design software is acceptable.
26. From question #25, which one of the things would cost the least (potentially free)? Explain
your answer in detail.
Web server software can be downloaded for free. Creating web page may only cost you
time.

27. Explain in detail how a web browser can locate and transfer a web page located on another
computer on the Internet even though the IP Address of that computer is not known.
The web browser sends out a request for a URL. This request is sent to the local DNS
Server of your network. If the local DNS server does not know the IP Address of the URL,
it forwards the request to a higher level DNS server (regional). This process continues until
some DNS Server recognizes the domain of the URL. The request is eventually forwarded
to the DNS Server responsible for the domain. This DNS Server can then direct it to the
local DNS Server where the web server is located. This DNS Server will likely know the IP
Address of the web server where the web page can be fetched.
28. If you were to register a domain name, i.e., www.yourname.com, what basic steps must be
completed before your website will be “visible” at www.yourname.com?
1. Register your domain name with an authority for a top-level high-level domain (i.e.,
.edu, .com, .org, etc.)
2. Update your local DNS Server so that your domain name is associated with your
computer’s IP Address, or contact your ISP and ask them to do it.
29. Draw a detailed picture of how a computer in RB330 is physically connected to (1) the file
server, (2) the web server, (3) the other computers, and (4) the Internet. Label each server with
the correct name and draw your diagram as accurately as possible.

Any picture that resembles this one is good.

30. Explain a logical reason why it takes 15 hops to connect to a web server at RPI from Siena
(five miles apart), whereas it takes only 12 hops to connect to a web server at Stanford, which is
thousands of miles away.
Because RPI and Siena have completely different Internet Service Providers, whose
networks are not locally connected. Or, because Stanford and Siena use Internet Service
Providers, whose networks are more directly connected.
31. Even though most people use search engines to find content on the WWW, why is it still
important for the WWW to include hubs. Recall that a hub is a website devoted to a particular
topic that includes links to other related websites. In other words, why do we still need hubs
even though most Internet users rarely use them?
Because Search Engines use hubs to identify and classify websites. Without hubs Search
Engines would not work so good. In fact, Search Engines are failing because web designers
are not creating hubs as they did in the past.
32. Given the following html code:
<html>
<head><title>44</title></head>
