| The Internet's continual growth has created previously inconceivable opportunities and problems in web-based teaching and learning. The original web, i.e. Web 1.0, began as a Read-only medium; the subsequent version, Web 2.0, set up itself as a Read and Write form of media. However, Web 3.0, the currently emerging version of the web, is believed to be a technology-driven medium that allows people to Read, Write and Execute and also enables robots to carry out some of the thinking previously expected solely from humans. Web 2.0, and now Web 3.0, have generated new resources and software for aiding web-based teaching and knowledge in a relatively short period.
