==== World wide web ====
World wide web (www) is an application on the internet, which allows computers to access the Internet in the form of a web page, using an application called the web browser. There are millions of pages of shared information on the computers in the network, created by many people and organizations, in the form of 'web pages' accessed using a software application called a 'web browser'.

A popular way of finding information on the Internet is through the use of a search engine. Search engine is a software that can retrieve a large amount of relevant information in very a short time.
The search engine has enormous implications for our processes of teaching-learning. In the past, rote learning (remembering information) has been seen as important, since such committing information to memory would allow us to access it when needed. Traditional Indian schools also had memorising scripts as an important learning method. However, with ICT, that has changed. Due to information explosion, it is now impossible to commit to memory the numerous aspects of our daily lives. Secondly, thanks to methods of storage and retrieval, including use of search engines, the need to memorise has also reduced. Twenty years back, we used to remember peoples telephone (land-line) numbers, which were not too many. Now with large number of contacts we have, we do not need to memorise their phone (cell phone) numbers, since we can store it in the phone itself and can retrieve by name. In the same way, any factual information can be retrieved in a fraction of a second and hence not worth memorising.

Thus while in the past, significant amount of teaching was actually the dissemination of information, now that would neither be required, nor would students readily accept it. Teaching has to hence necessarily move to the next order of interpreting, critically reflecting on facts to assess and make meaning. Thus in a way, search engines have done the processes of learning a good turn, by making information transmission as a largely redundant part of learning. On the other hand, they have also enabled easy copying of materials, without requiring much effort to understand, potentially encouraging superficial learning.
Internet is also allowing new methods of learning through on-line courses and resource repositories. Unit 1 will help you learn how you can use ICT to ''connect and learn''.
