IoT protocol stack overview in IOT Protocols - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main purpose of the IoT protocol stack?

The IoT protocol stack organizes communication rules into layers, helping devices connect, send data, and work together smoothly.

beginner

Name the four common layers in the IoT protocol stack.

The four common layers are: Physical Layer, Network Layer, Transport Layer, and Application Layer.

beginner

What does the Physical Layer in the IoT protocol stack do?

It handles the actual hardware and signals, like radio waves or cables, that send data between devices.

intermediate

Which protocols are commonly used in the Network Layer of IoT?

Common protocols include IPv6, 6LoWPAN, and RPL, which help route data between devices and networks.

beginner

Why is the Application Layer important in the IoT protocol stack?

It defines how data is formatted and understood by applications, enabling useful services like smart home control or health monitoring.

Which layer in the IoT protocol stack deals with sending raw signals like radio waves?

A Application Layer

B Physical Layer

C Transport Layer

D Network Layer

The Physical Layer handles the hardware and raw signals for communication.

What is the role of the Transport Layer in the IoT protocol stack?

A Managing data flow and reliability

B Routing data between devices

C Formatting data for applications

D Sending raw signals

The Transport Layer manages data flow and ensures reliable delivery.

Which protocol is commonly used for routing in IoT networks?

A MQTT

B HTTP

C RPL

D FTP

RPL is a routing protocol designed for low-power and lossy networks in IoT.

What does the Application Layer in IoT handle?

A Transport reliability

B Data routing

C Physical connections

D Data formatting and services

The Application Layer formats data and provides services for IoT applications.

6LoWPAN is a protocol used in which IoT protocol stack layer?

A Network Layer

B Transport Layer

C Physical Layer

D Application Layer

6LoWPAN operates at the Network Layer to enable IPv6 over low-power wireless networks.

Explain the main functions of each layer in the IoT protocol stack.

Think about how data moves from hardware to useful applications.

Describe why protocols like 6LoWPAN and RPL are important in IoT networks.

Consider the challenges of IoT devices like limited power and unstable connections.
