•Web 2.0 is a technical term meaning the next generation of World Wide Web products
and services.
•Web 2.0 is based on ideas and the applications of those ideas to integrate
communications and bring about the flow of traffic (collaboration on line).
•Making the flow of information / data multi-directional and free moving.
•Social Networking, Wikis, Twitter, Blogging, Facebook– all of these and many other
technologies and applications of Internet Traffic represent a fundamental change in the
level of participation for people using the Internet today.
•In the past applications were desktop based or client / server oriented. Today we’re
seeing more and more applications being browser based, mostly dependent on the web,
but with some offline components that allow an individual to continue work even when
their Internet connection is down or unavailable.

•A wiki allows a group of people to enter and communally edit bits of text. These bits of
text can be viewed and edited by anyone who visits the wiki.
•You can add or change anything you like in the article you are reading.
•This simplicity and the utter openness of a wiki cause many people to instantly reject the
idea.
•Where does all the information come from?
•Is it reliable?
•What stops people from vandalizing a wiki until it dies?

•When you sign up with Twitter, you can use the service to post and receive messages to a
network of contacts.
•Instead of sending a dozen e-mails or text messages, you send one message to your
Twitter account, and the service distributes it to all your friends.
•Members use Twitter to organize impromptu gatherings, carry on a group conversation
or just send a quick update to let people know what's going on.
•Tweets can only contain text -- members can't include pictures, video or other computer
files with Tweet messages.

•One of the things that is so amazing about blogs is their simplicity.
•A typical blog has a main page and nothing else. On the main page, there is a set of
entries.
•A blog is normally a single page of entries. There may be archives of older entries, but the
"main page" of a blog is all anyone really cares about.
•A blog is organized in reverse-chronological order, from most recent entry to least
recent.
•A blog is normally public -- the whole world can see it.
•The entries in a blog usually come from a single author.
•The tools that most bloggers use make it incredibly easy to add entries to a blog any time
they feel like it.

•Facebook is a social networking site giving people a way to share information in an easy
and entertaining way.
•Facebook will generate a profile for you.
•You can browse and join networks, which are organized into four categories: regions
(networks that are linked to specific cities or countries), colleges, workplaces and high
schools.
•Once you join a network, you can browse through the list of members and search for
people you know.
•You can let Facebook pull contacts from a Web-based e-mail account or to look for a
specific person.

•Wireless Fidelity ? No.
•Wi-Fi is an arbitrary mark that sounds very nice but has no particular meaning associated.
•Wi-Fi is a wireless networking technology that uses radio waves to allow high-speed data
transfer over short distances.
• Wi-Fi allows local area networks (LANs) to operate without cables and wiring, making it a
popular choice for home and business networks.
•Wireless-enabled devices are able to connect to the Internet when they are near areas that have
Wi-Fi access, called “hot spots.”
•Hot spots have become common, with many public places such as airports, hotels, bookstores,
and coffee shops offering Wi-Fi access.
•The radios used for WiFi communication are very similar to the radios used for walkie-talkies,
cell phones and other devices.

Video Conferencing
•3G is the short form used for third-generation technology.
•In 2008, 3G providers started delivering the 3G mobile broadband services.
•3G is the third generation of mobile phone standards and technology, superseding 2G.
•3G technologies enable network operators to offer users a wider range of more advanced
services while achieving greater network capacity through improved spectral efficiency.
•Services include wide-area wireless voice telephony, video calls, and broadband wireless
data, all in a mobile environment.
•For 3G services new networks need to be fitted and new frequencies are allocated to the
mobile operators.

•Bluetooth technology standard used to enable short-range wireless communication
between electronic devices.
•Because the protocol would operate on radio frequencies, rather than the infrared
spectrum used by traditional remote controls, such devices would not have to maintain a
line of sight to communicate.
•Bluetooth takes small-area networking to the next level by removing the need for user
intervention and keeping transmission power extremely low to save battery power.
•The big draws of Bluetooth are that it is wireless, inexpensive and automatic.
•Bluetooth networking transmits data via low-power radio waves. It communicates on a
frequency of 2.45 gigahertz.
•Bluetooth can connect up to eight devices simultaneously.
