Internet of Things (IoT)

The Internet of Things connects everyday physical objects — sensors, appliances, vehicles — to the internet so they can collect, exchange and act on data.

IoT enables smart homes, smart cities, industrial automation and connected healthcare by bridging the physical and digital worlds.

IoT Architecture

A typical IoT system has four layers: the sensing layer (sensors and actuators), the network layer (connectivity via Wi-Fi, Bluetooth, Zigbee, 5G), the processing layer (edge/cloud analytics), and the application layer (user-facing services).

Lightweight protocols such as MQTT and CoAP are used because IoT devices often have limited power and bandwidth.

Important Points to Remember

  • Connects physical devices to the internet for data exchange.
  • Four-layer architecture: sensing, network, processing, application.
  • Uses lightweight protocols like MQTT and CoAP.
  • Applications: smart homes, smart cities, industrial IoT, healthcare.
  • Edge computing reduces latency for IoT analytics.
  • Security and privacy are major challenges due to many endpoints.

Frequently Asked Questions

IoT is a network of physical devices embedded with sensors and connectivity that lets them collect and exchange data over the internet.

Common protocols include MQTT, CoAP, HTTP, and connectivity standards like Wi-Fi, Bluetooth, Zigbee, and 5G.

Weak device authentication, unencrypted data, large attack surface, and lack of regular updates make IoT systems vulnerable to attacks.
