Lecture Notes: Web 2.0

What is Web 2.0?

Web 2.0 is basically how we perceive the internet today. In today’s world of Web 2.0, data is not controlled by one person, but by many people. Users create their own content for the internet which in turn makes it more involved and interactive than just passively viewing a webpage. This encourages open communication between people all around the world who are linked and they are able to share, trade and collaborate. It’s all about participating, sharing and collaborating.

When designing for Web 2.0, we need to think about:

– Flexibility
– Context aware
– Publishing vs. participation
– Functionality
– Cross platform

What is Convergent Media?

Convergence is a cross over between:

– Communications Networks
– Computing Information Technology
– Content (Media)

The 3 “C”‘s of convergence.

All of this combined creates the internet, which is basically Web 2.0 and a global community.

Laurence Lessig describes convergent media as containing three layers:
  • Physical Layer: Network through which communications travels and communication devices are connected to one another.
  • Code Layer: Code or software that operates communications hardware devices – including protocols.
  • Content Layer: Content that is delivered through the communications infrastructure.
Web 2.0 plays a huge role in our everyday lives. Most people cannot imagine life without the internet because then there would be no sharing of ideas and thoughts and there would be no virtual interaction other than physical interaction with people around the world. It is human nature to share, trade and collaborate with one another and without Web 2.0, this would be made very difficult. The power of Web 2.0 allows us to easily execute these tasks quickly and efficiently.

The era of Web 2.0

The online world is changing. No longer are we just passively viewing a website without contributing to it in some way or expressing our opinions on a certain topic. That was known as Web 1.0, where people would view a website how the creator intended, without any user interaction. They could have no say on the subject unless it was discussed verbally in the physical world or by written documents.

Twitter allows users to update their statuses and follow groups, people or their favourite celebrity. It's all about user interaction.

The emergence of Web 2.0 has changed how people perceive and use the internet. It is now not just about viewing a website, it is now much more than that. It is about sharing and communicating with people around the world.

YouTube is a place where ordinary people can upload videos on to the web to share with the world. Thousands of videos are uploaded daily, and note that Youtube is not the only website that allows users to upload videos.

It is human nature to share, participate and be up to date with people around you. That is why websites like Facebook and Twitter allow users to share and participate in various activities. Letting friends know what you are doing or where you are at that very moment can be easy as one click of a button. And because these applications are now available on mobile phones, users can update their statuses on the go. It has never been so easy to share and connect with people around you.

A social network that's so popular, there are half a billion users and growing...

Web 2.0 has truly changed how the internet works. It has created a world where sharing and connecting with people is essential in our daily lives. And with technology growing more powerful by the year, it’s only going to get easier to connect.
