What is the use of MQTT in IoT?

In addition to being used as an underlying communications protocol for IoT and Industrial IoT architectures, MQTT is used in smart home automation systems alongside cloud platforms such as Microsoft Azure, AWS and IBM Watson. Facebook also uses MQTT as a communication protocol for its Messenger and Instagram platforms.

What are some of the benefits of using MQTT?

Advantages of MQTT:

• Efficient data transmission.
• Quick to implement as it is a lightweight protocol.
• Low network usage due to minimization of data packets.
• Fast and efficient message delivery.
• Uses very small amounts of power, which is good especially for the wireless devices.
• Reduction of network bandwidth in communication.

What is the main purpose of MQTT Mcq?

Explanation: MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol that provides resource-constrained network clients with a simple way to distribute telemetry information.

Which of the following communication model is used in MQTT?

MQTT has a client/server model, where every sensor is a client and connects to a server, known as a broker, over TCP. MQTT is message oriented. Every message is a discrete chunk of data, opaque to the broker. Every message is published to an address, known as a topic.

Who uses CoAP?

CoAP is designed to enable simple, constrained devices to join the IoT even through constrained networks with low bandwidth and low availability. It is generally used for machine-to-machine (M2M) applications such as smart energy and building automation.

Is CoAP open standard?

Both MQTT and CoAP: Are open standards.

What is the main purpose of M2M Mcq?

The main purpose of machine-to-machine technology is to tap into sensor data and transmit it to a network. Unlike SCADA or other remote monitoring tools, M2M systems often use public networks and access methods — for example, cellular or Ethernet — to make it more cost-effective.
