Web 2 refers to the second generation of the World Wide Web, characterised by interactive and user-generated content and the ability to connect and share information online. Web 2 introduced many of the technologies and platforms that are now essential to using the internet, including social media, blogs and wikis.
One of the most important features of Web 2 is the ability for users to actively participate and contribute to the content of a website rather than just consuming content created by others. This has led to the emergence of a variety of online communities and social networks where users can share their thoughts, ideas and experiences with others.
Web 2 has also greatly changed the way businesses and organisations use the internet. Many companies use social media and other online platforms to connect with their customers and promote their products and services.
