    Study Notes

    Internet of Things (IoT) Definition

    • IoT stands for "Internet of Things"
    • IoT involves connecting devices with sensors and actuators to the internet.

    Drivers for IoT Evolution

    • Unification of technologies like low-power embedded systems, cloud computing, big data, machine learning, and networking drive IoT evolution.

    IoT Enables

    • RFID (Radio Frequency Identification) enables tracking and identification of objects.
    • Nanotechnology allows for the development of smaller, more efficient sensors and devices.
    • Sensors act as the primary input mechanism for gathering data in IoT applications.

    IoT Gateway

    • Connects the IoT Local Area Network (LAN) to a Wide Area Network (WAN)
    • Implements several LANs and WANs
    • Forwards packets between LAN and WAN on the IP layer
    • Has a unique address prefix for global identification.

    Multi-homing in IoT

    • A node or network can connect to multiple networks to improve reliability.

    True/False Statements

    • The ITU vision of interconnected devices exceeding human population is becoming a reality.
    • IoT Proxy performs active application layer functions between IoT devices and other entities.

    IPv4 Address Representation

    • The IPv4 notation uses 32 bits to represent an address.
    • The "Destination Address" field in the IPv4 header is 32 bits long.

    Sensors and Actuators

    • Sensors are used to detect and measure physical parameters like temperature.
    • Sensors are classified as analog or digital based on their output.
    • An actuator is a device that receives a signal to control or actuate a process or system.
    • The full form of SMP in the context of IoT actuators is not mentioned in the text.
