Communication

• Communication through satellites has emerged as a new area in communication technology since the 1970s.

• However, with the digitization of information in the 1990s, telecommunication slowly merged with computers and constituted an integrated network termed the Internet. 
• Today, the Internet is the largest electronic network on the planet connecting more than 1,000 million people in more than 100 countries of the world.
• Indian satellite Aryabhatt was launched on April 19, 1979, Bhaskar-I in 1979, and Rohini in 1980.

• Further, on 18 June 1981, APPLE (Arian Passenger Payload Experiment) was launched through the Arian rocket. Thereupon, a series of satellites have been launched for different purposes.
• Cyberspace is the world of electronic computerized space. It consists of the Internet such as on the World Wide Web (www).
• Currently, the majority of the internet users in the world are living in U.S.A., U.K., Germany, Japan, China, and India.

• Cyberspace has been expanding the contemporary economic and social space of humans through e-mail, e-commerce, e-learning and e-governance.
• Likewise, these modern communication systems, more than transportation, have made the concept of a global village a reality.
