Web
What does Web mean?
The Web is the common name for the World Wide Web (WWW), a subset of the
Internet consisting of the pages that can be accessed by a web browser. Many
people assume that the web is the same as the Internet, and use these terms
interchangeably. However, the term Internet actually refers to the global network of
servers that makes the information sharing that happens over the web possible. So,
although the web does make up a large portion of the Internet, but they are not one
and same.
Web pages are formatted in a language called Hypertext Markup Language
(HTML). It this language that allows users to click through pages on the Web via
links. The web uses HTTP protocol to transmit data and share information. Browsers
such as Internet Explorer, Google Chrome or Mozilla Firefox are used to access
web documents, or Web pages, which are connected via links.
The web is just one of the ways that information is shared over the Internet; others
include email, instant messaging and File Transfer Protocol (FTP).
Evolution of the Web
Web 1.0
Web 1.0 refers to the first stage in the world wide web,
which was entirely made up of web pages connected by
hyperlinks. Although the exact definition of Web 1.0 is a
source of debate, it is generally believed to refer to the web
when it was a set of static websites that were not yet
providing interactive content. In Web 1.0, applications were
also generally proprietary.

Exactly where Web 1.0 ends and Web 2.0 begins cannot be determined as this a
change that happened gradually over time as the internet became more interactive.
Since 2004, Web 2.0 has been the term used to describe the social web, where
social networking sites hold a prominent place in users' online activities. The shift
to this more interactive web from Web 1.0 generally occurred as a result of
technological changes that made the internet – and the ability to develop content
– more accessible. These changes include broadband internet, better browsers,
AJAX and the mass development of widgets. In Web 2.0, applications are also more
likely to be open source, providing users with a greater ability to influence the web.
Web 2.0
Web 2.0 is the name used to the describe the
second generation of the world wide web, where
it moved static HTML pages to a more interactive
and dynamic web experience. Web 2.0 is focused
on the ability for people to collaborate and share
information online via social media, blogging
and web-based communities.
Web 2.0 signaled a change in which the world wide web became an interactive
experience between users and web publishers, rather than the one-way
conversation that had previously existed. It also represents a more populist version
of the web, where new tools made it possible for nearly anyone to contribute,
regardless of their technical knowledge.
The meaning of the term Web 2.0 has evolved over time, but it has come include
social media as a major component. Although community has always been a part
of the web, new web applications such as AJAX and more modern browsers began
providing opportunities for people to express themselves online as never before,
and to combine applications to create a more integrated web. By 2005, the term web

2.0 was well-established, and companies such as Google made huge strides to
integrate information online. For example, a website that reviews restaurants may
use social media, user-generated content, photographs from Flickr, Google
maps, and content from around the web to create a more complete user
experience.
Web 3.0
Web 3.0 is stated to be the new paradigm in web interaction
and will mark a fundamental change in how developers create
websites, but more importantly, how people interact with
those websites. Computer scientists and Internet experts
believe that this new paradigm in web interaction will further
make people's online lives easier and more intuitive as
smarter applications such as better search functions give users exactly what they
are looking for, since it will be akin to an artificial intelligence which understands
context rather than simply comparing keywords, as is currently the case.
Web 3.0 will be a complete reinvention of the web, something that Web 2.0 was
not. Web 2.0 was simply an evolution from the original web which can be compared
to a library, as Web 1.0 was essentially an infodump, a place where people just
placed walls upon walls of text which people can read but usually not interact
with. Web 2.0 changed this by allowing user interaction with dynamic websites that
acted more as applications than simply pages of information.

There is no concrete definition for Web 3.0 yet and the technology that will bring us
there has not even matured yet. So to get a better understanding of Web 3.0, let us
look at an example. In the current Web 2.0, users can interact with websites that
have predetermined behaviors according to the input of users. Users can search for
information using various search engines which generally provide satisfactory
results if there is enough information regarding the search. However, that search is
only for keywords and brings in the most popular information available, and does not
understand the context of the search. So if a user searches for an insect called a
camaro and uses only that one word, then about 90 percent of the search results are
for the Chevy Camaro model of car and not the insect because the car is the most
popular search result and has the most prolific information. However, Web 3.0 will
be able to get the context from the user; and then be able to provide the user with
the most useful information about the camaro insect, such as its habitat and even
where to find it as a delicacy. Web 3.0 can be likened to an artificial intelligence
assistant that understands its user and personalizes everything.
Furthermore, if someone is preparing for a vacation and needs to search for cheap
flights and accommodations as well as
meals, they must look through a lot of
information on the web comparing
different selections and the search
might take hours. But Web 3.0 search
engines or assistants will be able to
scrape all of this information and
present it to the user in a very intelligent
way, even making highly accurate and
favorable suggestions based on the
user's profile.
Web 2.0 Tools

There are many web 2.0 tools we may use for teaching and learning. However we
will not have enough time for exploring all of then; however, we will explore and
use some of them.
