We will attempt to consolidate our learning on newteoks by browsing the Networks Basic Interactive Tutorial to further understand some of the basics about networking.
After that, you will complete the Networking Basics Tutorial at 3com. You must complete the final quiz.
Finally, in pairs, you will write two questions about doubts you still have on networking and send them to itgs.sass@gmail.com You will be graded on how teh questions reflect your knowledge and understanding of networks.

Networks
The next topic that we will be dealing with is networks. We will be analyzing the fundamentals of networks, different topologies and other technical concepts as a first step towards discussing the implications of networks on society and individuals.
We will start, as an introduction, by watching the following animation that depicts graphically how Internet works:
Then we will cover the basics and fundamentals of Networking through How Stuff Works.
How Ethernet Works

Presentation
We have covered several technical topics lately, and this assignment will focus on discussing some of the implications on individuals and societies of the their technological applications.
Working in groups of 3 students, you will develop a PowerPoint presentation that addresses one of the following topics/statements:
- Users are forced into buying expensive computers in order to sustain operating systems that do not give extended functionality. Open source operating systems would not require a constant upgrading.
- Most organizations or firms do not adequately address the issue of ergonomics and as such millions of dollars are lost every year as a consequence of repetitive stress injuries.
- In the future, most people will work from home and many important social interactions will be lost, as well as the ability to function as a team.
- Passwords are an unsafe and inadequate method to gain data access. Biometric recognition will be the standard in the near future, since affordable and accurate biometric recognition methods are now available.
Each presentation must address the above issues including external links, at least two multimedia elements (videos) linked from the presentation, and arrive at a conclusion with respect to the statement presented. You must email your finished presentation to itgs.sass@gmail.com by the end of teh lesson on Wednesday, April 21st.
During the first lesson, the plan for the presentation must be drawn up and approved. You will not actually start working on the presentation but rather identify how you will tackle it as well as finding the links and resources that you plan to include.
In order to learn about effective and ineffective PowerPoint presentations, we will browse the Death by PowerPoint presentation.

Assessment 1
Answer all questions, save them to a Word file, name it with your surname and submit it to itgs.sass@gmail.com
DO NOT LEAVE THE LAB UNTIL YOU HAVE CHECKED THAT I RECEIVED THE FILE.
The questions have been written so that you are able to analyze and respond by demonstrating your mastery of the topics. PLEASE DO NOT COPY FROM WEB SITES.
1- Explain how when a URL is typed at a web browser the correct web page gets loaded at the client computer. Give technical details of every stage in the process.
2- The owner of a new online sports good store wants to promote his business and hires you to ensure that when people search for sports goods on a search engine his store appears prominently. Explain in detail how you would help him achieve this through two different strategies.
3- Giving technical reasons, explain why Google has established itself as the best search engine. How do you rate a search engine?
4- Based on what we saw in the Yahoo video and what was discussed in class, what can we expect search engines to do in the future that they cannot do now?
5- How is a search engine constructed? Outline the different stages in the process. Why is so much hardware needed? What costs need to be covered in running a search engine?
6- You are teaching a 5th grade class how to use a search engine. What advice would you give them in terms of rating the reliability of a site and constructing a query so that they get to the desired outcome?

Teleworking - Biometrics - Ergonomics
During the next few classes, we will be discussing some general issues related to technology use and access, as well as their implications.
Ergonomics: is the application of scientific information concerning objects, systems and environment for human use (definition adopted by the International Ergonomics Association in 2007). However, the field of Ergonomics is mostly associated with the design of hardware in such a way that it prevents commonly known repetitive stress injuries RSI. Ergonomics at work is a video that illustrates some of these concepts.
Teleworking: Globalization and recent changes and technological advances have made it possible for an increasing number of people to be able to work from home. Managing Strategies For Telework - The Virtual Workforce is an article that provides a good summary of the advantages and disadvantages of working from home.
Password Protection – Biometrics: Any organization that possesses valuable information needs to put into effect some sort of validation process that ensures that only authorized users can gain access to relevant information. There are many different authentication methods, from the very simple and straightforward Passwords) to more complex ones based on biometrics. We will watch the following two videos to jumpstart our discussion:
