Edge gateway architecture in IOT Protocols - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is an edge gateway in IoT?

An edge gateway is a device that connects local IoT devices to the cloud. It processes data near the source to reduce latency and bandwidth use.

beginner

Name two main functions of an edge gateway.

1. Data filtering and processing close to devices.<br>2. Secure communication between devices and cloud.

Why is local data processing important in edge gateway architecture?

Local processing reduces delay, lowers bandwidth use, and improves response time by handling data near the source instead of sending everything to the cloud.

What role does security play in edge gateway architecture?

Edge gateways secure data by encrypting communication and managing device authentication, protecting the network from unauthorized access.

How does an edge gateway help with device protocol translation?

It translates different device communication protocols into a common format so devices can communicate with cloud systems smoothly.

What is the primary purpose of an edge gateway in IoT?

A Process data near devices to reduce latency

B Store all data permanently on the device

C Replace cloud servers completely

D Only connect devices to Wi-Fi

Edge gateways process data close to devices to reduce delay and bandwidth use.

Which of these is NOT a function of an edge gateway?

A Data filtering

B Device authentication

C Cloud data storage

D Protocol translation

Cloud data storage is handled by cloud servers, not edge gateways.

How does an edge gateway improve security?

A By storing passwords in plain text

B By encrypting data and managing device access

C By disabling all device connections

D By ignoring device authentication

Edge gateways secure communication by encrypting data and authenticating devices.

What is a benefit of local data processing at the edge?

A Faster response times

B More cloud storage needed

C Increased network traffic

D Slower device communication

Processing data locally reduces delay, making responses faster.

Edge gateways help devices communicate by:

A Replacing device sensors

B Removing device firmware

C Blocking device signals

D Translating different protocols

They translate various device protocols into a common format for smooth communication.

Explain the key components and functions of an edge gateway architecture.

Think about how data moves from devices to cloud and what the gateway does in between.

Describe why edge gateways are important in IoT systems compared to sending all data directly to the cloud.

Consider the challenges of sending all data to the cloud and how edge gateways help.
