Key Subfields of AI:

1. Machine Learning (ML): Statistical systems that automatically improve their performance through experience (e.g., email spam filtering, recommendation engines).
2. Natural Language Processing (NLP): Enables computers to understand, interpret, and manipulate human language (e.g., Siri, Google Assistant, ChatGPT).
3. Computer Vision: Enables machines to identify and process images, videos, and faces (e.g., facial recognition unlock, medical image diagnosis).

2. Big Data & The 5 Vs

Big Data refers to datasets whose size, complexity, and rate of growth make them impossible to capture, store, manage, and analyze using conventional relational database tools.

    BD --> V1["1. Volume: Massive scale (Petabytes / Exabytes)"]
    BD --> V2["2. Velocity: Real-time streaming speed"]
    BD --> V3["3. Variety: Structured, Semi-structured, Unstructured"]
    BD --> V4["4. Veracity: Trustworthiness & Data Quality"]
    BD --> V5["5. Value: Actionable business intelligence extracted"]

The 5 Vs Summary Table:

Characteristic	Definition	Real-World Example
Volume	The immense amount of data generated	Billions of daily transactions across global banks
Velocity	The speed at which new data is generated and streamed	Live social media feeds, IoT telemetry
Variety	The diverse forms of data (SQL tables, JSON, videos, logs)	RDBMS rows, sensor readings, MP4 video streams
Veracity	The degree of reliability, accuracy, and noise in data	Filtering fake accounts or sensor glitches
Value	The business insight or societal benefit derived	Predicting disease outbreaks or fraud detection

3. Cloud Computing

Cloud Computing is the on-demand delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the Internet ("the Cloud") with pay-as-you-go pricing.

    Cloud --> SaaS["SaaS (Software as a Service)<br><i>Delivers fully managed software applications over web</i><br>Examples: Gmail, Google Drive, Microsoft 365"]

Cloud Deployment Models

• Public Cloud: Owned and operated by third-party cloud providers (e.g., AWS, Azure) delivering services over the public internet.
• Private Cloud: Cloud infrastructure used exclusively by a single business or organization.
• Hybrid Cloud: Combines public and private clouds, allowing data and apps to be shared between them.
• Community Cloud: Shared by multiple organizations with common compliance or regulatory goals.

4. Internet of Things (IoT) & Smart Systems

The Internet of Things (IoT) is a network of physical devices (sensors, smart appliances, vehicles) embedded with electronics, software, and network connectivity that enable them to collect and exchange data.

• Web of Things (WoT): Integrates everyday smart devices with web standards (HTTP/HTML) for standardized control.
• Smart Cities: Leveraging IoT sensors for real-time traffic management, automated street lighting, smart water grids, and automated waste collection.

5. Blockchain Technology

A Blockchain is a decentralized, distributed, and immutable public ledger that securely records transactions across a peer-to-peer network without relying on a central authority.

Core Features of Blockchain:

1. Decentralization: No single entity controls the network.
2. Immutability: Once a block is verified and cryptographically chained, records cannot be altered or tampered with.
3. Smart Contracts: Self-executing digital contracts with terms directly written into code.

6. Virtual Reality (VR) vs Augmented Reality (AR)

Feature	Virtual Reality (VR)	Augmented Reality (AR)
Experience	Completely immerses user in a computer-generated artificial environment	Overlays digital objects/information onto the real-world view
Hardware	Dedicated VR Headsets (e.g., Meta Quest, HTC Vive)	Smartphones, Smart Glasses (e.g., Google Lens, Pokémon GO)
Real-World Visibility	User is isolated from physical surroundings	User continues to see physical surroundings with digital augmentations
