Job Aid – Introduction to the Internet
IMPORTANT NOTE: Please review this entire job aid prior to teaching the session on Introduction to the
Internet.
TAP (Topic-Audience-Purpose)
Topic: Introduction to the Internet and Internet Protocol (IP) Camera Surveillance
Audience: Select group of twelve (12) employees at Technical Surveillance Specialists (TSS), a company
based in Coral Gables, Florida. The employees typically come from a military or a law enforcement
background, and have a wide range of computer literacy.
Purpose of Instruction: These employees are receiving training on Internet Protocol cameras as a
surveillance tool. Since the employees have such a wide range of computer literacy (ranging from those
who barely use a computer to those who are quite computer-savvy), the client would like to level the
playing field and start off with an introductory session about the Internet and how it relates to IP
cameras.
Time: This training is scheduled to take 3 hours to complete.

LEARNING ACTIVITIES
Activity 1
IP Addresses and URLs
•
Have the learners open a web browser and type in the following IP addresses. These addresses
should bring up the following websites:
•
http://157.166.226.25 (CNN)
•
http://207.68.172.246 (MSN)
•
http://216.35.221.77 (NPR)
•
http://199.239.137.245 (NY times)
•
http://64.233.187.99 (Google)
•
The point of this exercise is to illustrate how much easier it is to use URLs. It also serves to
subtly introduce the learners to what an IP address looks like.
•
You can use a utility called WHOIS to identify who owns an IP address. You can search by the
website name (the domain name) or the IP address. Have the learners access the WHOIS
website by using Google and inputting WHOIS. The WHOIS.net website should pull up. Have the
learners search for some domain names.
•
Now, go to this link: http://tools.whois.net/yourip/ so learners can identify their IP address.
Does everyone have the same IP address? Who owns this resource?
Activity 2
Internet and Networking Terms
•
Assign each of the pairs a group of words. This will allow them to search for their own
information and learn from each other. Have them find the terms in their workbooks. To save
time, users will be able to select the definitions from a list.
•
Web sites to use:
•
http://webopedia.internet.com/
•
http://whatis.techtarget.com/
•
http://www.techterms.com/internet.php

Main network connection composing the Internet; moves data
along at very high speeds and for very long distances
The amount of data you can send through a network or modem
connection
Connects two or more LANs together; doesn't analyze data just transports it
Stores recently retrieved information so it can be accessed

actually makes the request
Dynamic Host Configuration Protocol; dynamically assigns IP
addresses to networked computers
Short for domain name system; helps match names of sites to
their IP addresses
Name that identifies a web site
Network where data is transmitted through Ethernet cables;
ethernet connections (and cables) are also used in wireless
networks
Limits the data that can pass through it and protects a
networked server or client machine from damage by
unauthorized users; can be hardware or software based
A computer that is connected to a TCP/IP network; has a
unique IP address
A node that provides Wireless access to the Internet for users
of portable computer devices; often available for a fee in public
places

Activity 3
Class Discussion – Why IP Cameras?
•
Take this opportunity to lead a class activity where they present the pros and cons of using IP
cameras for surveillance. They are convincing their supervisor not only about IP cameras, but
how data is transmitted across the Internet.
•
Allow 15 minutes for this activity. Jot down the responses on a flip chart.
Film Clip
Warriors of the Net is a short (13-minute) video clip tracing the journey of data packets through the
Internet. Once the film is complete, allow time for questions.
CLASSROOM DISCUSSIONS
To prepare for the classroom discussions, make sure you have reviewed the PowerPoint and the Student
workbook prior to the classroom session. The PowerPoint provides you with some talking points. Feel
free to elaborate on the talking points as necessary. You can print out the PowerPoint presentation in
notes view to review the talking points.
When using the PowerPoint, keep in mind that animations are included on the slides and that you
should not read the PowerPoint to the learners. The PowerPoint can be used to help you stay on track.
BREAKS and Q&A
There is one 15-minute break scheduled during the session, but feel free to adapt based on the needs of
your learners. Allow time for Q&A as often as possible, but be sure to guide the discussion and not to go
too far off on tangents.

ASSESSMENTS and SURVEYS
Prior to class, set up the post classroom session survey in Survey Monkey. Allow 15-20 minutes at the
end of the first day of classroom training for students to log into Survey Monkey and answer the
questions. The assessment questions for the introductory session are included in this document, but
other questions will have to come from the rest of the classroom materials. This assessment will not be
graded, but by using Survey Monkey, you can still determine how many learners provided correct
answers. Survey Monkey provides free reporting on survey responses, so you can analyze this survey
instantly.
