Lesson 2.3

• Web 1.0 is commonly associated as the initiated or the first stage of the WWW. The first stage of the web was made up of web pages and was entirely connected by hyperlinks. Well, the official definition for this version is a moot.
• Web 2.0. The second stage of WWW Web 2.0 is identified by the modification from static to dynamic web pages which are better organized and are completely based on serving web applications, user-generated content to the end users. Web 2.0 is not only readable but also writable form with a connection to data. It allows the end users to navigate and to interact in a better way. It cheers the participation and data sharing.
• Web 3.0 is referred as the new pattern in web and the evolution of Web 2.0 that will mark the changes in the creation of websites and particularly in what way people reach out to those websites. It is the executable clause of WWW with dynamic services. Web 3.0 is the read, write and executable format of WWW. It can easily read the data just like human and could also distribute or tailor the useful content to the end users.
• Web 1.0 - accessible as Read Only Mode, simply web. To connect information.
• Web 2.0 - accessible as ReadWrite-Mode, social web. To connect people.
• Web 3.0 - accessible as ReadWrite-Execute Mode, semantic web. To connect Knowledge.
• The term technological convergence is often defined in a very generalized and simplified terms as a process by which telecommunications, information technology and the media, sectors that originally operated largely independent of one another, are growing together. Technological convergence has both a technical and a functional side.
• Types of internet:

  1. Dial-up
  2. DSL (Digital Subscriber Line)
  3. Cable
  4. Wireless
  5. Satellite
  6. Cellular
  7. Fiber optic
• Dial-up Internet became commercially available in the 1990s.
• A DSL (Digital Subscriber Line) broadband Internet came after dial-up.
• The next advancement in the field was cable Internet access, which remains the most commonly used form of the Internet in 2020. It combined existing DSL telephone networks and cable television infrastructure to bring the best of both worlds.
• Wireless LAN or WLAN is becoming more and more common in residential homes because of smart devices such as smartphones, tablets, and virtual assistant devices.
• For those places that rely on dial-up Internet or places where an Internet connection cannot be achieved, satellite Internet might be the only choice.
• Cellular - Have you heard about the 5G controversy and conspiracy theories? It is an advanced version of widely used cellular networks, 3G and 4G.
• Fiber Optic - Instead of copper, thin glass wires are used to transmit data, and because light signals travel rapidly, this reduces latency. Although speed might be affected by the bouncing of light, it is still mind-numbingly fast.
