Introduction of information technology and society
Week ONE: Introduction to information technology and society; WEB 1.0 v 2.0 v3.0
WEB 1.0
When web was in its early days; people didn’t know what to show on the computer screen
Static web – it was a search for online viability.
WEB 2.0
When we got a grip of the technical part, the real possibilities of the web became clear
Discovered the power of networks – power of links, collaboration, content and research, friends.
Technical aspect of the web didn’t change as much, web 2.0 was more of a SOCIAL change
No longer linking ext but linking people
Blogging is the most recognised example of web 2.0
Social networks connect users into a community or trust (with common interests)
RSS (really simple syndication) – emerging technology which enable users to get ‘feeds’ of data from content publishers via a browser or a special newsreader tool. Items come to users free of spam, on demand, and on an easy to digest format.
WEB 3.0
Driven by technological changes
The semantic web – it’s about the MEANING of data
WHY IS WEB CHANGING?
People coming together instead of replacing each other
Web users, ‘Generation C’, have started controlling their own programming through blogs, sharing images and creating personalised ‘away’ messages on IM.
WEB 2.0 – the evolution towards a read/write platform
