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 pairs, 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.

During today's lesson, you will plan and find resources for the presentation. You have to show me the plan before the end of the lesson.

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 post your finished presentation to your blogs by the end of the lesson next Thursday.

In order to learn about effective and ineffective PowerPoint presentations, we will browse the Death by PowerPoint presentation.

Search Engines Test

Answer all of these questions on a Word document and, before leaving the room, send your Word file to itgs.sass@gmail.com

Important instructions: please answer all questions fully and including the technical terms that we studied. Provide detailed explanations for each question.

1. A student at  school is loading a web site at one of the computers in the lab. From the moment they type the URL until the page gets loaded on the computer, describe in detail, using technical terms, how the information flows from the workstation in the lab, through the school network towards the server and back.  
2. 2) Explain, using all technical terms that are relevant, how a search engine can perform a search. How does it know which sites best match the search query? What technically makes a search engine better than the others?
3. 3) An Argentine rugby web site hires you to make sure that whenever people are searching for information on rugby in the country their site appears at the top of the search.  How would you do that? Give details using technical terms.
4. 4) What are the privacy risks faced by users when searching and using the Internet in general? Give examples.
5. 5) Can somebody jokingly or with bad intentions create a web site to damage your reputation? How would that be done?
6. 6) Write some ideas about the future of search engines? What type of search engines can we expect for the future?
