Bullets: AI → Big Data → IoT → Cloud → Grid → Blockchain. Visualizes progression from intelligence to distributed systems.

Why This Guide Stands Out

Comprehensive: All trends point-wise, figure integrations; 2025 with ethics (e.g., AI bias), analyzed for digital society.

Artificial Intelligence (AI)

  • Definition: Simulate human intelligence in machines (learning, decisions); e.g., Siri/Alexa.
  • Subsystems: ML (algorithms learn from data, train/test models); NLP (voice search, translation, text-to-speech; Fig 2.1).
  • Immersive Experiences: VR (3D simulated world, headsets; Fig 2.3 gaming/training); AR (overlay digital on real; Fig 2.4 location apps).
  • Robotics: Programmable machines (sensors key); types: Wheeled/legged/humanoids/drones; ex: Mars Rover (Fig 2.5), Sophia (Fig 2.6), drones (Fig 2.7 delivery).
  • Knowledge Base: Facts/assumptions for AI decisions.
  • Think & Reflect: NLP for disabled (voice aids); robots in medicine (surgery).
  • Expanded: Evidence: Auto-tagging; debates: Job loss; real: VR therapy 2025.

Big Data

  • Definition: Enormous voluminous/unstructured data (2.5 quintillion bytes/day; Fig 2.8 sources: social/email).
  • Characteristics (5Vs; Fig 2.9): Volume (size), Velocity (generation rate), Variety (structured/unstructured), Veracity (trustworthiness), Value (hidden patterns).
  • Challenges: Integration/storage/analysis; traditional tools insufficient.
  • Data Analytics: Examine sets for conclusions; tools: Pandas (Python lib).
  • Think & Reflect: Digital activities contribute (posts/tweets); drones in calamity (mapping).
  • Expanded: Evidence: Noisy data risks; debates: Privacy; real: Analytics in e-commerce 2025.

Internet of Things (IoT)

  • Definition: Network of embedded devices communicating (Fig 2.10: bulbs/fans/smartphones).
  • WoT: Web services for unified interface (one app for all devices; smart homes/cities).
  • Sensors: Detect environment (accelerometer/gyro in phones); smart sensors process input.
  • Smart Cities (Fig 2.11): IoT/WoT for resource mgmt (sensors in bridges/tunnels/buildings for alerts).
  • Activity: List IoT devices (smartwatch/refrigerator); VPS (AR navigation utilities).
  • Think & Reflect: Transform city ideas (traffic sensors).
  • Expanded: Evidence: Remote control; debates: Security; real: 5G IoT 2025.

Cloud Computing

  • Definition: On-demand services over Internet (hardware/software; pay-per-use like electricity).
  • Services (Fig 2.12): IaaS (infra like VMs/storage), PaaS (platform for apps, e.g., pre-config Apache), SaaS (apps like Google Docs).
  • Benefits: Cost-effective, scalable; GI Cloud (MeghRaj).
  • Activity: Data centers in India (e.g., AWS Mumbai - storage).
  • Expanded: Evidence: No upfront investment; debates: Vendor lock-in; real: Hybrid clouds 2025.

Grid Computing

  • Definition: Network of dispersed resources as virtual supercomputer (Fig 2.13: shared nodes).
  • Types: Data grid (distributed access), CPU grid (parallel tasks).
  • Vs Cloud: Application-specific vs service-oriented; middleware: Globus Toolkit.
  • Think & Reflect: Assistive trends for disabilities (AI voice, IoT wearables).
  • Expanded: Evidence: Reuse idle resources; debates: Scalability; real: Scientific simulations 2025.

Blockchains

  • Definition: Decentralized shared ledger (blocks chained; Fig 2.14: transaction broadcast/verify).
  • Features: Append-only, secure (all nodes authenticate); vs centralized (hack risk).
  • Applications: Crypto, healthcare (sharing), land records, voting; transparency in governance.
  • Think & Reflect: Other areas (supply chain, education certs).
  • Expanded: Evidence: No single alter; debates: Energy use; real: NFT/Web3 2025.
