1. Telecommunications GROUP 2 P6-VIC CHLOE TEO, NICOLE KOO, LIM JAN JAY, ARJUN DEV

2. Vast array of technologies that can be used from a distance Examples include: mobile phones, satellite phones, landlines, telegraphs and the Internet. What is "Telecommunication"?

3. THE INTERNET A MAGNIFICENT INVENTION. SO MAGNIFICENT THAT MAJORITY OF OUR LIVES REVOLVE AROUND IT.

4. Definition/Description In·ter·net [in-ter-net] Noun A vast computer network linking smaller computer networks worldwide (usually preceded by the). The Internet includes commercial, governmental, and other networks, all of which use the same set of communications protocols. Origin: 1990–95

5. Definition/Description The Internet is commonly used in our daily lives. Even as I’m typing this and researching, I am also using the Internet. The Internet brings us convenience and also entertainment. However, it does have its pros and cons. But how was it invented? Who was the guy who came up with the idea of the Internet? What if we didn’t have Internet in our lives? These are all questions that we should ask ourselves.

6. The National Science Foundation (NSF) established five super computing centers in 1986, creating the NSFnet backbone. In 1987, the NSF signed a cooperative agreement to manage the NSFnet backbone with Merit Network, Inc., and by 1990, ARPAnet had been phased out. NSFnet continued to grow, and more and more countries around the world connected to this Internet backbone. The National Research and Education Network (NREN) was founded and the World Wide Web was released in 1991—a huge event. History of Development

7. In the late 1960s, the United States Defense Department developed ARPAnet (Advanced Research Projects Agency network), an experimental network of computers designed to things like bomb attacks to create a web of computers that could continue to communicate with each other, even if some of the computers were disabled. In the mid-1980s, when desktop computer workstations became increasingly popular, organizations wanted to connect their local area networks (LANs) to ARPAnet. History of Development

8. The Internet is still dominated by scientists and other academics, but begins to attract public interest. With the release of the Mosaic Web browser in 1993 and Netscape in 1994, interest in and use of the World Wide Web exploded. More and more communities become wired, enabling direct connections to the Internet. History of Development

9. In 1995, the NSFnet reverted back to being a research network. Interconnected network providers are strong enough now to support U.S. backbone traffic on the Internet. However, the presidential administration encourages continued development of the U.S. backbone of the Internet, also knows as the National Information Infrastructure (NII)-- and, most commonly, as the "Information Superhighway". History of Development

10. Benefits of this Development Convenient way of communicating with other people Easier way to derive information A good source for entertainment Formation of communities and groups Services (eg. online shopping, job searching, etc.)

11. Disadvantages of this Development Wrong kinds of information can be spread throughout the internet (e.g. false info) Bad influences (e.g. vulgarities, gossip, etc.) Children spend too much time on the internet--family bonding time is lost People trusting unreliable sources may lead to viruses being spread from device to device

12. Impacts on the Environment NEGATIVE IMPACTS

13. Carbon Footprint? The energy footprint of the entire internet doesn’t just include the data centres—it also includes the devices we use the Internet on (eg. Computers, mobile phones, iPads) as well as some other factors.

14. Carbon Footprint? Actually, the world’s PCs and monitors account for around 40% of the total ICT energy demand and 0.8% of global CO2 emissions. So the Internet would contribute around 1% of all the CO2 emissions released from burning fossil fuels. Which means that the internet releases around 300m tonnes of CO2.

15. We hope you learnt something new. IF NOT, IT’S OKAY. YOU CAN ALWAYS DO YOUR OWN RESEARCH.
