If so many things are impacted by ICT, it is important to understand how these work, and how they should be used [[ICT_student_textbook/What_students_need_to_know_about_ethics_of_technology|ethically and safely]].  Technology should be treated like a common resource where everyone can access it, interact with it, benefit from it and contribute to it.  It should be used such that more and more people can get access in society should be treated like a public information good.

|If you want information about some book available in your library, you can connect to the library's computer from home and get the information that you want. There are many such computers in different organisations giving us different types of information. These computers are connected to one another, their network is called the Internet. 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 millions of computers which are part of the Internet, is like a huge library with information on almost any issue.  Initially the internet was a set of computers connected by one another and information requests were sent and received through networks.

|But this was difficult.  In 1989 Sir Timothy Berner Lee developed a system by which the computers can transfer information through a method called '''Hyper Text Mark-up Language'''.  <br>
 +
This application is called the "World Wide Web - www".  Yes, the "www" is an application on the internet 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'''.<br>
 +
This makes connection between computers more accessible to all and it allows different kinds of content to be shared across the internet.  This was a significant shift in the way the internet developed.
