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 EXPECTATIONS Learning Goals and Objectives By the end of this session, the learners should be able to: 1. Comfortably maneuver inside a Web Browser 1.1. Access the Internet through various web browsers, including Internet Explorer and Mozilla Firefox. (Psychomotor) 1.2. Access specific web sites to find definitions of key Internet and networking terms so that a class discussion can take place. (Psychomotor, Cognitive – Application, Affective – Receiving and Responding) 2. Define or recognize examples of basic Internet and networking terms 2.1. Identify differences in types of Internet connections, networks, and network security standards, based on classroom discussions. (Cognitive – Knowledge, Cognitive – Comprehension) 3. Describe how data flows through the Internet 3.1. Identify how data is transmitted through the Internet based on information provided in the film clip from Warriors of the Net. (Cognitive – Knowledge, Affective – Receiving) 4. Describe the basic operation of an IP camera 4.1.

TIMELINE This lesson will be three hours long. By the end of this session, all of the goals and objectives should be reached. Activity Time Introductions, Agenda, and Materials 8:30-8:45 Discussion: Web Browsers and URLs 8:45-9:00 Activity 1: IP Addresses and follow-up discussion 9:00-9:15 Activity 2: Discovery – Internet and Networking Terms 9:15-9:35 Discussion: Internet and Networking Terms 9:35-10:05 Break 10:05-10:20 Video: Warriors of the Net and Follow-Up Discussion 10:20-10:40 Discussion: IP Cameras and Surveillance 10:40-11:00 Activity 3: Class Discussion – Why IP Cameras? 11:00-11:15 Q&A 11:15-11:30 Job Aid - Introduction to the Internet Page 2 of 8 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 Job Aid - Introduction to the Internet Page 3 of 8 Terms included in activity: Term Group Definition 802.11 a/b/g/n 1 Backbone 3 Bandwidth 4 Bridge 5 Cache 6 Client 1 DHCP 4 DNS 2 Domain Name 3 Ethernet network 6 Firewall 6 Host 3 Hot spot 2 HTTP 3 Hub 4 Internet 5 Intranet 1 IP 2 Specifications for Wireless Local Area Networks; data is transmitted over either the 2.4 GHz band or the 5 GHz band at various speeds (up to 100 mbps) 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 again very quickly In a client/server relationship, the program or device that 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;

wireless routers typically include a firewall and allow users to share an Internet connection In a client/server relationsihp, the device that provides the information Has many definitions, but on the Internet, this device determines the output port to use so data packets continue to travel to their correct destination Stands for Transmission Control Protocol/Internet Protocol; breaks information into packets on the sending end and reassembles them on the receiving end User datagram protocol; part of TCP/IP; considered 'stateless' because it doesn't acknowledge the packets have been received;

consists of pages that can be accessed using a web browser 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. Job Aid - Introduction to the Internet Page 6 of 8 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. ASSESSMENT QUESTIONS – INTRODUCTION TO THE INTERNET 1.
