    Study Notes

    Internet of Things (IoT) Module 1

    • IoT is a technology transition allowing devices to sense and control the physical world, connecting objects through an intelligent network.
    • The goal of IoT is to "connect the unconnected" objects not currently connected to a computer network.
    • IoT enables tighter integration between the physical world and computers, improving efficiency, accuracy, automation, and advanced applications.
    • Kevin Ashton is credited with creating the term "Internet of Things" in 1999 while working for Procter & Gamble.
    • IoT's evolution can be categorized into four phases: connectivity, networked economy, immersive experiences, and Internet of Things.

    Genesis of IoT

    • Kevin Ashton, working at Procter & Gamble in 1999, coined the term "Internet of Things" to link the company's supply chain to the internet.

    Business and Societal Impact

    • Connectivity: Digitizes access through email, web browsers, search.
    • Networked Economy: Digitizes business via e-commerce, digital supply chain, and collaboration.
    • Immersive Experiences: Digitizes interactions, including social media, mobility, cloud, and video.
    • Internet of Things: Digitizes the world by connecting people, processes, data, and things.

    Convergence of IT and OT

    • IT (Information Technology) focuses on internet connectivity and secure data flow, while OT (Operational Technology) monitors and controls physical systems like production facilities.
    • OT failure has a significantly greater impact on business than an IT system failure.
    • A key difference lies in the scale and priority of the systems. OT prioritizes keeping the operations running, while IT supports communications.

    IoT Challenges

    • Scale: IoT networks, especially electrical grids, can be significantly larger than typical IT networks.
    • Security: The larger the network, the more vulnerabilities and potential threat surfaces.
    • Privacy: Individuals' and organizations' concerns about data ownership, usage, and control are increasing.
    • Data Analytics: Handling massive volumes of data from numerous sources efficiently.
    • Interoperability: Establishing standardized protocols and architectures for IoT devices to work together and communicate.
