Q. 1: Briefly explain the technical difference between the Internet and the World Wide Web (www).
Ans: The terms Internet and the World Wide Web are often used interchangeably but technically these two terms have different meanings. The World Wide Web is a part of the Internet which is the net of innumerable computers connected with each other, making it a very large network. The World Wide Web uses the Internet for the purpose of communication. In this process, communication on the Internet is made easier, enjoyable and productive by the web. Internet browsers are used to connect with the World Wide Web on the Internet. Internet or the interconnection of computer networks is a huge combination of personal and business computers which was started in 1960 under the name of ARPnet. It was originally designed for the US military to help it maintain communications in the event of a possible nuclear strike.
Question 2: Briefly describe the term multimedia search engines. As a teacher, describe how you might be able to use some of the resources that you found.
Answer: multimedia search engines can index and search digital multimedia archives. As audio and video content is difficult to browse these search engines can save a lot of time and effort in finding the relevant content. Similarly, indexing multimedia content is more complex than indexing the text content. Continuous media like videos is broken into chunks for achieving better precision in the search results by the multimedia search engines.
There are several advantages of multimedia search engines. As a teacher the resources found on various multimedia search engines like Alta Vista.com, www.alltheweb.com, www.ditto.com, Google images, Picsearch and Singingfish could help in locating audio video files or images from across the web. We can search images or videos by selecting the image or the video tab provided on the search engines. There’s also an audio tab in some search engines which helps us locate audio files on the web. These tools can be quite effective in teaching and learning and many institutions are experimenting with these new approaches. It is considered that it could be a valuable method of encouraging development of higher order thinking skills like analyzing, synthesizing and evaluating. These approaches also aim at developing the problem-solving abilities of the young people and develop the ability to work in groups and learn lifelong skills. The relevance of these skills for life in information economy is well recognized now.
