Introduction

1.       What is the Internet?

The Internet, is a worldwide system of computer networks - a network of networks in which users at any one computer can, if they have permission, get information from any other computer.

 

2.       Why was the internet created?

The Internet came in the late 1960s with the creation of the Advanced Research Projects Agency Network (ARPANET). Originally funded by the U.S. Department of Defence, ARPANET used packet switching to allow multiple computers to communicate on a single network.

 

3.       What effect has it had on society?

 

·         Wireless communication.

·         Media report that intense use of the Internet increases the risk of isolation, alienation, and withdrawal from society in some cases. However, it increases sociability, civic engagement, and the intensity of family and friendship relationships, in all cultures.

·         People, companies, and institutions deal with this technological change.

·         The rise of the “Me-cantered society,” gave an increased focus on individual growth and a decline in community understood in terms of space, work, family, and ascription in general.

·         Social relationships are being reconstructed on the basis of individual interests, values, and projects.

·         Community is formed through individuals’ quests for like-minded people in a process that combines online interaction with offline interaction, cyberspace, and the local space.
