The internet is a physical network of millions of computers across the world, each of which has a unique identifier. Some of these computers act as 'servers', they store data which can be accessed by other computers. The Internet is thus like a huge library with information on almost any issue. The 'web-sites' we visit are nothing but folders of computers connected to the internet. Apart from information, many of these computers also have applications or web tools, such as search engine, maps, translation, which have different purposes.

Information can be accessed in multiple ways from the Internet and we need to know how to search for information on the Internet. Sources of information, even if freely available on the Internet, needs to be acknowledged. Resources are available in different formats on the Internet- images, videos, audio files etc. We must be aware of Internet safety while accessing images, videos and other information on the Internet. We already saw that each website is a page on the Internet and has an address. We can either copy and paste the link directly in the address bar of the browser (shown above). Another 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.

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'.

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.

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''.
