WEB falls into different (3) categories
Web1: This is what we call 'Static' Read-only web, Eg Google and some browsers, traditional example your new-papers or magazine you can read but cannot add or ask questions
Web2: This is what we call 'Interactive web' Read-Write, this means you can read, contribute and share your opinion, but it's centralised. Eg WhatsApp, Facebook, Twitter and other social media apps.
