ICT and Web Evolution: Web 1.0 to Web 3.0 Study Notes

Introduction to Information and Communication Technologies (ICT)

  • ICT is a tool for curating, contextualizing, collaborating, and creating content and experiences for learning in professional tracks.

Lesson Objectives and Key Takeaways

  • At the end of the lesson, students should be able to:
    • 1. Improve their knowledge on how ICT affects everyday life and the nation.
    • 2. Compare and contrast the differences between online platforms, sites, and content.
    • 3. Understand the features of Web 2.0.
    • 4. Understand the future of the World Wide Web through Web 3.0.
    • 5. Learn different ICT trends and leverage them.

What ICT Is (Definitions and Scope)

  • ICT uses different communication technologies (e.g., mobile phones, telephone, Internet) to locate, save, send, and edit information.
  • ICT is an umbrella term referring to communication hardware or software that allows access, storage, transmission, and manipulation of information.

Current State of ICT and Convergence

  • Convergent Technology: multiple devices combine into a single gadget due to technological advancement.
  • Example devices often discussed in convergence: desktops/laptops, mobile phones/smartphones, televisions and radios.
  • Convergence leads to devices becoming smaller, more capable, and networked.

Key ICT Devices and Platforms

  • Smartphones: modern portable computing devices enabling broad communication capabilities.
  • Social media: software, applications or platforms that allow users to communicate in online communities or networks; enables faster communication with a large audience.
  • Commonly used social media sites: a variety of platforms used for social interaction, information sharing, and content creation.

Types of Social Media (Six Categories)

  • Social Networks
  • Bookmarking Sites
  • Social News
  • Media Sharing
  • Microblogging
  • Blogs and Forums

Mobile Technologies and Operating Systems

  • Mobile technologies refer to devices that are easily carried and enable fast communication; historically bulky, now compact due to advancement.
  • Operating systems used by mobile phones include:
    • iOSiOS

Assistive Media

  • Assistive Media is a nonprofit service designed to help people with visual and reading impairments.
  • It uses a database of audio recordings to read content aloud to users.

Internet vs World Wide Web: Distinctions

  • Internet:
    • A global network of networks enabling worldwide communication and access to data resources; a network of private, public, business, academic, and government networks.
  • World Wide Web (WWW):
    • A system of public websites or pages accessible via the Internet; it links documents and pictures into a database stored on computers worldwide.
  • Abbreviations: WWW and Web.

World Wide Web vs. Internet (Further Clarifications)

  • The Web is a subset of the Internet, focusing on linked documents and multimedia accessible through browsers.

Web 1.0: Read-Only Web

  • When the Web was invented, most pages were static (not interactive) and content was the same for all users.
  • Web 1.0 is described as the Read-Only Web by Tim Berners-Lee: users could only read content created by others; pages were largely static.

Web 2.0: Read-Write Web

  • Web 2.0 is the evolution of Web 1.0, introducing dynamic pages and user interaction.
  • Examples include social networks, blogs, wikis, video sharing sites, hosted services, and web applications.
  • Web 2.0 allows users to interact with pages (comment, create accounts) and to use web browsers for UI, applications, and even file storage.
  • Web 2.0 is characterized as Read-Write: users can post, share, comment, rate, and participate.

Features of Web 2.0

  • Folksonomy (user-generated tagging and categorization)
  • Rich user experience
  • User participation
  • Long tail (niche content and markets)
  • Software as a Service (SaaS)
  • Mass participation

Web 3.0 and the Semantic Web

  • The Semantic Web is a W3C-led movement encouraging semantic content on web pages.
  • The Semantic Web provides a common framework for data to be shared and reused across applications, enterprises, and communities.
  • The aim of Web 3.0 is to enable machines to understand user preferences to deliver targeted web content.

Web 3.0: Execution and Personalization

  • Web 3.0 envisions executable interactions: devices can accept user requests and execute solutions by integrating data from various sources.
  • Example: A restaurant suggestion is generated by scanning the internet for data, applying context (time, prior preferences, seat availability), and potentially reserving a table.
  • Note: Web 3.0 is not yet fully realized and is still developing; concepts may evolve.

Challenges and Considerations in Web 3.0

  • Several problems of Web 3.0 include:
    • COMPATIBILITYCOMPATIBILITY
    • SECURITYSECURITY
    • VASTNESSVASTNESS
    • VAGUENESSVAGUENESS
    • LOGICLOGIC

Activity: The Future of ICT

  • Prompt: In the past, telephones were used for long-distance communication and were not mobile. Today, a pocket-sized device enables communication.
  • Task: Imagine an ICT device twenty 2020 years from now and write an essay describing what it is and what it does.
  • Requirements: At least 200200 words; provide a name and describe the device and its work.

Inspirational Closing

  • Quote: “Imagination is more important than knowledge.” — ALBERT EINSTEIN
