    Study Notes

    Big Data

    • Big Data works on the principle that the more you know about anything or any situation, the more reliably you can gain new insights and make predictions about what will happen in the future.
    • Activities involved with big data processing are:
      • Ingesting data into the system
      • Persisting the data in storage
      • Analyzing data and computing insights
      • Visualizing the results

    Big Data Terminologies

    • Data mining: Refers to deep dive into the data to extract the key knowledge / Patterns / Information from a small or large amount of data.
    • Data analytics: Involves collecting data from different sources, preparing it, and delivering data products useful to the organization's business.
    • Machine learning: Is the field of study and practice of designing systems that can learn, adjust, and improve based on the data fed to them.

    Augmented and Virtual Reality

    • Augmented Reality (AR): Layers computer-generated enhancements over an existing reality to make it more meaningful through interaction.
    • AR combines real and computer-based spectacle and pictures to transfer a unified but enhanced view of the world.
    • Examples of AR: Snapchat lenses, The game Pokémon Go.
    • Virtual Reality (VR): A realistic and immersive simulation of a three-dimensional environment, created using interactive software and hardware.
    • Mixed Reality (MR): Combines real and virtual spaces, allowing users to navigate through both simultaneously.

    Advantages and Disadvantages of AR/VR

    • Advantages: Training, Education, Entertainment, and Gaming, Help and Healing, Architecture and Planning
    • Disadvantages: Loss of spatial awareness, Eye soreness, Seizures, Nausea, Dizziness, and Disorientation

    Challenges of AR/VR

    • Price is too high
    • Content is lacking
    • Lack of viable business models
    • Health effects
    • VR perceived as a gimmick
    • Ethical issues
    • Social impact

    Big Data

    • Big Data is an evolving term that describes a large volume of data, structured, semi-structured, and unstructured data.
    • Unstructured data: Doesn't have any pre-defined structure and comes in various forms, such as image files, text files like PDF.
    • Structured data: Is clearly defined and searchable, commonly exists in tables similar to Excel files and Google Docs spreadsheets.

    Blockchain

    • Blockchain is a decentralized, high-secure, and transparent system with faster processing.
    • Applications of blockchain: Education, Health, Government
    • Disadvantages of blockchain: High energy consumption, High costs, Soft fork, Hard fork
    • Challenges of blockchain: User privacy protection, Processing speed, Finalizing transactions, Coordination with existing systems, Block chain reliability

    Bio and Nano Technology

    • Biotechnology is an industry that applies biology to solve real-world problems.
    • Biotechnology is the process of changing living species or biological processes to benefit human activities.
    • Biotechnology aims to improve human life by developing or making products or processes that use biological systems, living organisms, or modify products or processes for specific use.
