Information and communication technology (ICT) involves using technologies like mobile phones, telephones, and the internet to locate, save, send, and edit information. ICT includes technologies like Web 2.0 that allow users to interact with websites through commenting or creating user accounts rather than just reading static pages. Other aspects of ICT are long tail services offered on demand, software as a service where users subscribe only when needed, mass participation through universal access, and folksonomy where users categorize information.
