2. How the Internet came about The foundations of the Internet were formed when packet-switching networks came into operation in the 1960s. Transmitted data is broken up into small packets of data, sent to its destination, and reassembled at the other side. This means that a single signal can be routed to multiple users, and an interrupted packet may be re-sent without loss of transmission
3. History Summary 1960s Research on computer networks On September 2, two computers at University of California, Los Angeles, exchange meaningless data in first test of Arpanet, an experimental military network. The first connection between two sites UCLA and the Stanford Research Institute in Menlo Park, California takes place on October 29, though the network crashes after the first two letters of the word "logon." UC Santa Barbara and University of Utah later join.

Netscape's developers pull the plug on the pioneer browser, though an offshoot, Firefox, remains strong. Major airlines intensify deployment of Internet service on flights. (Agencies)

31. Trends of Internet 2010 Media consumption Due to increasingly empowered consumers and further advances in technology, media will become more Distributed, Personalized, Contextualized. Advertising Advertising will support less and less of the load for content and entertainment. Fueled by the low cost of digital distribution, combined with vast amounts of consumer-generated content in the form of blogs, social networks, photo- and video-sharing sites, and rampant Twitter activity, media choices have exploded.

33. Trends of Internet 2010 Social Media– Facebook, Twitter etc Businesses will continue or increase their investment in online communities and social media and, for the majority of these companies, their marketing function will drive this investment. Webinars Webinars are already changing the landscape on how people meet for business on the cheap, and worry the airlinesMobile Smartphone usage will continue to increase and mobile payments will become one of the preferred venues for payments. The iTunes Store has lead the way with interesting services like Square surfacing to redefine how you and I can utilize our phones to pay for stuff while surfing online
34. Trends of Internet 2010 Real-time The term represents the growing demand for immediacy in our interactions. Immediacy is compelling, engaging, highly addictive... it is a sense of living in the now and that is why you should expect to see more real-time in the coming months as Google Wave reaches its maturity, Facebook tries real advantage from the acquisition of FriendFeed and real-time protocols like PubSubHubbub become really top-notch. Content curation In the attention economy, with its millions of daily status updates and billions of web pages vying for your time, how do we best allocate that scarce resource? Twitter has distinguished itself as the forefront application for breaking news, and anybody can use Twitter Lists to curate Twitter feeds by topic, geography and industry.
35. Trends of Internet 2010 Cloud computing This trend, boomed back in 2008 and persistently growing in 2009, will shift even more data and applications from your desktops to servers elsewhere ("the cloud"), making data accessible from anywhere and enabling collaboration with distributed teams. Giants like Microsoft, Apple and Adobe are already moving in this direction. Open source Open source software projects, typically for the purview of programmers or at least technophiles, will be available to the masses and will also generate revenues thanks to a simple infrastructure that can live in the cloud and offer services for small subscription fees.
37. Internet future 1. More people will use the Internet. Today's Internet has 1.7 billion users, according to Internet World Stats. This compares with a world population of 6.7 billion people. There's no doubt more people will have Internet access by 2020. Indeed, the National Science Foundation predicts that the Internet will have nearly 5 billion users by then. So scaling continues to be an issue for any future Internet architecture.
38. Internet future 2. The Internet will be more geographically dispersed. Most of the Internet's growth over the next 10 years will come from developing countries. The regions with the lowest penetration rates are Africa (6.8%), Asia (19.4%) and the Middle East (28.3%), according to Internet World Stats. In contrast, North America has a penetration rate of 74.2%. This trend means the Internet in 2020 will not only reach more remote locations around the globe but also will support more languages and non-ASCII scripts.
39. Internet future 3. The Internet will be a network of things, not computers. As more critical infrastructure gets hooked up to the Internet, the Internet is expected to become a network of devices rather than a network of computers. Today, the Internet has around 575 million host computers, according to the CIA World Factbook 2009. But the NSF is expecting billions of sensors on buildings and bridges to be connected to the Internet for such uses as electricity and security monitoring. By 2020, it's expected that the number of Internet-connected sensors will be orders of magnitude larger than the number of users.
40. Internet future 4. The Internet will carry exabytes — perhaps zettabytes — of content. Researchers have coined the term "exaflood" to refer to the rapidly increasing amount of data — particularly high-def images and video – that is being transferred over the Internet. Cisco estimates that global Internet traffic will grow to 44 exabytes per month by 2012 — more than double what it is today. Increasingly, content providers such as Google are creating this content rather than Tier 1 ISPs. This shift is driving interest in re-architecting the Internet to be a content-centric network, rather than a transport network.
41. Internet future 5. The Internet will be wireless. The number of mobile broadband subscribers is exploding, hitting 257 million in the second quarter of 2009, according to Informa. This represents an 85% increase year-over year for 3G, WiMAX and other higher speed data networking technologies. Currently, Asia has the most wireless broadband subscribers, but the growth is strongest in Latin America. By 2014, Informa predicts that 2.5 billion people worldwide will subscribe to mobile broadband.
42. Internet future 6. More services will be in the cloud. Experts agree that more computing services will be available in the cloud. A recent study from Telecom Trends International estimates that cloud computing will generate more than $45.5 billion in revenue by 2015.
43. Internet future 7. The Internet will be greener. Energy Intensity is growing at a slower rate than data traffic volumes as networking technologies become more energy efficient. The trend towards greening the Internet will accelerate as energy prices rise, according to experts pushing energy-aware Internet routing.
44. Internet future 8. Network management will be more automated. Among the ideas under consideration are automated ways to reboot systems, self-diagnosing protocols, finer grained data collection and better event tracking.
45. Internet future 9. The Internet won't rely on always-on connectivity. Techniques that tolerate delays or can forward communications from one user to another in an opportunistic fashion, particularly for mobile applications which called delay-tolerant networking.
46. Internet future 10. The Internet will attract more hackers. In 2020, more hackers will be attacking the Internet because more critical infrastructure like the electric grid will be online. Symantec detected 1.6 million new malicious code threats in 2008 – more than double the 600,000 detected the previous year. Experts say these attacks will only get more targeted, more sophisticated and more widespread in the future.
