Information and Communication Technologies – Lesson 1 Study Notes

Self-Reflection: Digital Habits

  • Four diagnostic questions invite students to examine their own ICT usage:
    • "How many times have you checked your phone this morning?"
    • "How many status updates have you posted in Facebook or Twitter today?"
    • "Did you use the Internet for an hour after you woke up this morning?"
    • "Do you follow a celebrity via his/her social-media account?"
  • Pedagogical purpose: primes learners to recognize the pervasiveness of ICT in daily life and serves as informal baseline assessment of digital dependence.
  • Ethical angle: pushes students to reflect on potential over-reliance on digital media, attention economy, and data privacy.

Digital Native

  • Definition: A person “born or brought up during the age of digital technology and therefore familiar with computers and the Internet from an early age.”
  • Significance:
    • Shapes cognitive expectations (immediacy, multitasking).
    • Drives educational approaches (e-learning, flipped classrooms).
    • Highlights a digital divide with “digital immigrants.”

Lesson 1 Learning Goals

  • By lesson end, students should be able to:
    1. Explain how ICT shapes personal life and national development.
    2. Differentiate online platforms, sites, and content.
    3. Describe key features of Web 2.0.
    4. Envision the future Web 3.0 and its user-centric features.
    5. Identify current ICT trends and apply them advantageously.

Information & Communication Technologies (ICT)

  • Core definition: Use of computing and telecommunication technologies to create, collect, process, transmit, store, and edit information.
  • Technologies encompassed:
    • Computing hardware: servers, laptops, IoT devices, metaverse hardware.
    • Networking: wired & wireless Internet, telephony, M2M links.
    • Software: operating systems, applications, cloud services.
  • Overarching goal: improve access to information and streamline human-to-human, human-to-machine, and machine-to-machine (M2M) communication.

ICT in the Philippines (Case Study)

  • Nickname: “ICT Hub of Asia.”
  • Key drivers:
    • Business Process Outsourcing (BPO) / call-center industry.
    • Mobile penetration: 106.8106.8 cellphones per 100100 Filipinos (2012, ITU data).
    • Social-media culture: Time Magazine’s 2013 “Selfiest Cities” ranked two Philippine cities #1 and #10 worldwide via Instagram analytics.
  • Implications: strong labor market in ICT, high social-media engagement, policy need for cybersecurity & digital literacy.

Evolution of the World Wide Web

Web 1.0 – Static Web
  • Early WWW: mostly static or “flat” pages; content identical for all users; minimal interaction.
  • Technologies: basic HTML, GIF images, “read-only” experience.
Web 2.0 – Dynamic & Social Web
  • Paradigm shift: user-generated content, interaction, and richer interfaces.
  • Users see personalized views; browsers operate as de-facto OS for web apps and cloud storage.
  • Everyday examples: social networks, blogs, wikis, video-sharing, hosted SaaS tools.
Core Features of Web 2.0
  1. Folksonomy – user-defined tagging (hashtags #) for categorization.
  2. Rich User Experience – responsive, location-aware, account-based content.
  3. Long Tail – on-demand services & granular pricing (time-based vs. bandwidth-based data plans).
  4. User Participation – comments, polls, reviews (e.g., Amazon ratings).
  5. Software as a Service (SaaS) – rental model for apps (e.g., Google Docs) instead of one-time purchase.
  6. Mass Participation – culturally diverse contributions enabled by global connectivity.
Web 3.0 – Semantic & Intelligent Web
  • Vision steered by W3C: embed semantic data so machines understand content & user preferences.
  • Goal: deliver context-aware, personalized information across applications, enterprises, and communities.
  • Expected abilities: predictive services, intelligent agents, voice/AR interfaces.
Challenges & Limitations
  1. Compatibility – current HTML & browsers insufficient for full semantic payload.
  2. Security & Privacy – storing detailed user preferences increases vulnerability.
  3. Vastness – billions of pages complicate semantic tagging.
  4. Vagueness – imprecise language (“old,” “small”) confuses automated reasoning.
  5. Logic Boundaries – machine logic may fail at nuanced human context.

Emerging Trends in ICT

1. Convergence
  • Technological synergy: multiple functions converge in single devices (smartphones), cross-platform content (Netflix on TV & phone).
2. Social Media
  • Definition: online channels enabling users to create, co-create, discuss, modify, and exchange user-generated content.
Six Types

a. Social Networks – connect people with shared interests (Facebook).
b. Bookmarking Sites – manage web links (Pinterest, Diigo).
c. Social News – user-submitted news links (Reddit).
d. Media Sharing – upload images, music, video (YouTube, Flickr).
e. Microblogging – short status updates (Twitter).
f. Blogs & Forums – long-form posts & threaded discussions (WordPress, Stack Exchange).

3. Mobile Technologies
  • Smartphones & tablets rival PCs in capability; enable ubiquitous computing.
Major Mobile Operating Systems
  • iOS, Android, BlackBerry OS, Windows Phone OS, Symbian, webOS, Windows Mobile\text{iOS},\ \text{Android},\ \text{BlackBerry OS},\ \text{Windows Phone OS},\ \text{Symbian},\ \text{webOS},\ \text{Windows Mobile}
4. Assistive Media
  • Adaptive, assistive, rehabilitative tech for elderly or users with special needs.
  • Forms: mobility aids, hearing aids, environmental modifications, screen readers.
  • Societal impact: promotes inclusivity & universal design principles.

Online Systems, Functions & Platforms

Definition of Online Systems
  • Integrated use of software, hardware, and Internet within an identified platform to deliver services.
  • Core data operations: storing, retrieving, editing.
Typical Online Functions
  1. Rapid search & research of information.
  2. Accelerated transactions vs. manual processes (e.g., e-banking).
  3. Organization of records from single/multiple transactions.
  4. Comprehensive data management for online activities.
  5. Automated workflows that reduce labor for providers & clients.
Online Platforms
  • Range of Internet tools providing above functions:
    • Search engines: Google, Yahoo, Bing.
    • Social-media platforms.
    • Web-creation tools.
    • Cloud computing & file-management suites.
    • Specialized systems: LMS (Moodle), transportation reservation systems, e-commerce carts, enrollment portals.

Ethical, Philosophical & Practical Implications

  • Digital dependency vs. wellbeing.
  • Data privacy, surveillance capitalism, algorithmic bias in Web 3.0.
  • Accessibility mandates (assistive media) aligning with inclusive philosophies.
  • Economic shifts (BPO boom) triggering workforce re-skilling.

Numerical & Statistical References (Quick Sheet)

  • Mobile penetration (PH 2012): 106.8/100106.8/100 phones per capita.
  • Instagram “Selfiest Cities” (2013): Philippine cities ranked 1st & 10th globally.

Quick Connections to Previous & Future Lessons

  • Builds on foundational computing history (previous lecture) by zooming into Internet era.
