From this lesson, the main information I have grasped is about Web 2.0 vs Web 1.0.
I have learnt that Web 2.0 is a platform that allows people from all around the world to collaborate, interact and share information. Whereas, Web 1.0 only allows people to obtain information, unable to allow people to share, interact, and so, knowledge is limited because only one perspective can be presented.
Web 2.0 sites allows its users to interact with other users or to change website content, in contrast to Web 1.0's non-interactive websites where users are limited to the passive viewing of information that is provided to them.
Web 2.0 sites include Facebook, Twitter, Wikipedia etc.
Web 1.0 sites are practically non-existent today, judging by the rate technology improves nowadays.
