INTRODUCTION TO ICT
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.
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 3.0 and The Semantic Web
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.
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.
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.
​
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.
​
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.
Different Types of Social Media
1. Social media is a website, application, or online
channels that enable web users to create, co-create, discuss, modify, and exchange user-generated content.
2. Social Networks. These are sites that allow you to connect with other people with the same interests or background.
3. Bookmarking Sites. These are sites that allow you to store and manage links to various websites and resources.
