Information and Communication Technology (ICT)
deals
with the use of different communication technologies such as mobile phones,
telephone, Internet, etc. to locate, save, send and edit information.
3
Versions of the World Wide Web
Web
1.0:
When
the World Wide Web was invented, most web pages were static. Static (also known
as flat page or stationary page) in the sense that the page is “as
is” and
cannot
be manipulated by the user. The content is also the
same for all users. This is referred to as Web
1.0.
WEB
2.0: Dynamic Web Pages
Web 2.0 is the evolution of Web 1.0 by adding
dynamic web pages—the user is able to see a website differently than others. Examples of Web 2.0 include social
networking sites, blogs, wikis, video sharing sites, hosted services, and web
applications.
Web 2.0 allows users to interact with the
page: instead of just reading a page, the user may be able to comment or create
a user account. Web 2.0 also allows users to use web browsers instead of just
using their operating system. Browsers can now be used for their user
interface, application software (or web applications), and even for file
storage.
Features
of Web 2.0
1.Folksonomy.
It
allows users to categorize and classify/arrange information using freely chosen
keywords (e.g., tagging). Popular social networking sites such as Twitter, Instagram,
Facebook, etc. use tags that start with the pound sign (#). This is also
referred to as the hashtag.
●
2.Rich
User Experience. Content is dynamic and is responsive to the user’s input. An example would be a website that shows local content. In the
case of social networking sites, when logged on, your account is used to modify
what you see on their website.
3.Long Tail. Services
are offered on demand rather than on a one-time purchase. In certain cases,
time-based pricing is better than file-size-based pricing or vice versa.
●
4.User Participation. The
owner of the website is not the only one who is able to put content. Others are
able to place the content of their own by means of comment, reviews, and
evaluation. Some websites allow readers to comment on an article, participate
in a poll, or review a specific product (e.g., Amazon.com, online stores,
wiki).
5.Software
as a Service. Users will subscribe to software only
when needed rather than purchasing them. This is a cheaper option if you do not
always need to use the software. Ex: Google Docs is a free web-based application that
allows the user to create and edit word processing and spreadsheet documents
online.
6.Mass
Participation. It is diverse information sharing
through universal web access. Since most users can use the Internet, Web 2.0’s
content is based on people from various cultures.
Web
3.0 and the Semantic Web
The Semantic
Web is a the movement led by the World Wide Web Consortium (W3C). “The Hyperconnectivity”
version.
Examples:
4G, Smart Phone, Android Phones, Search Engines, Online Food, Dress, and Taxi
services…
According to the W3C, “The Semantic Web
provides a common framework that allows data to be shared and reused across
application, enterprise, and community boundaries.”
The aim of
Web 3.0 is to have machines (or servers) understand the user’s preferences to
be able to deliver web content specifically targeting the user.
CONVERGENCE
•is
progressively common in the IT world; in this setting, the term alludes to the
blend of two or more distinctive advancements in a solitary gadget. Bringing
pictures with a cell phone and surfing the Web on a TV are two of the most
widely recognized cases of this pattern.
Several
problems of Web 3.0
1.
Compatibility
HTML files and current web browsers could not
support Web 3.0.
2.
Security
The user’s security is also in
question since the machine is saving his or her preferences.
3.
Vastness
The World Wide Web already contains
billions of web pages.
4.
Vagueness
Certain words are imprecise. The
words “old” and “small” would depend on the user.
5.
Logic
Since machines use logic, there are
certain limitations for a computer to be able to predict what the user is
referring to at a given time.

Trends in
ICT
1. Convergence
Technological
convergence is
the synergy of technological advancements to work on a similar goal or task.
2. Social
Media
Social
media is a
website, application, or online channels that enable web users to create,
co-create, discuss, modify, and exchange user-generated content.
six
types of social media:
a.Social Networks. These are sites that allow you to

updates from the user.
f.Blogs and Forums. These websites allow users to post
their content.
3. Mobile
Technologies
The popularity of smartphones and tablets has taken a major rise over the years.
This is largely because of the devices’ capability to do tasks that were
originally found in personal computers.
Kinds
of operating systems:
a.iOS
b.
Android
c.Blackberry
OS
d.Windows
Phone OS
e.Symbian
f.WebOS
g.Windows Mobile
4. Assistive
Media
Assistive
media is a
nonprofit service designed to help people who have visual and reading
impairments. A database of audio recordings is used to read to the user.
