    Study Notes

    Machine to Machine Communication (M2M)

    • M2M allows direct data exchange between devices without human interaction, enhancing automation in industrial settings.
    • Applications include communication from sensors or meters, such as temperature and inventory levels, to software systems for decision-making processes.
    • Connectivity options encompass serial connections, powerline communications, and a growing trend towards wireless protocols in the industrial IoT.
    • M2M networks facilitate end-to-end connectivity through a combination of radio, gateways, core networks, and backend servers.

    Differences Between M2M and IoT

    • M2M focuses on direct communication between machines, while IoT encompasses broader connectivity, integrating devices into the internet for enhanced interaction.
    • M2M is designed for point-to-point connections; IoT utilizes cloud-based architectures for scalability.
    • Devices in M2M can operate independently of the internet, unlike IoT, which relies on internet connectivity.
    • M2M supports limited device connections simultaneously, whereas IoT allows for greater scalability and concurrent user access.
    • M2M typically lacks support for open APIs, while IoT often includes such functionalities, promoting integration and innovation.

    Terminology in IoT

    • Microprocessor: a compact integrated circuit designed to process information.
    • Microcontroller: a small computer on a single integrated circuit containing a processor, memory, and programmable input/output peripherals.
    • Embedded System: a computer designed to perform dedicated functions within a larger system.
    • API (Application Programming Interface): a set of protocols for building and interacting with software applications.
    • Latency: the delay before a transfer of data begins following an instruction.
    • Telemetry: automated data collection from remote sources.
    • SoC (System on Chip): integrates all the components of a computer or electronic system onto a single chip.

    Internet of Things (IoT)

    • IoT involves connecting everyday objects and sensors to the internet, allowing them to generate, exchange, and process data with minimal human input.
    • Facilitates remote monitoring and control through integration with communication technologies.
    • Enables a vast network of interconnected devices, enhancing automation across various sectors.

    Cybersecurity in M2M and IoT

    • Password attacks exploit vulnerabilities in user authentication systems, with brute-force methods and dictionary attacks being common tactics.
    • Types of malware attacks include macro viruses, file infectors, system infectors, Trojans, and ransomware, each employing distinct strategies for infiltration.

    System Errors and Debugging

    • Possible reasons for system failure include overheating, dust accumulation, faulty fans, power connection issues, and uninstalled drivers.
    • Debugging involves identifying and resolving these potential hardware and software malfunctions.

    Smart Living Environments

    • Smart technologies in homes include automation for lighting, doors, and multimedia systems, reacting to human presence or environmental changes.
    • Devices like smart fridges, chairs, clocks, mirrors, and furniture adapt to user needs, enhancing convenience and efficiency.
    • Advanced features allow these systems to communicate, improving user interaction and overall functionality.
