IoT

Question 1

IoT definition

Answer 1

network of physical objects embedded with sensors, software, and other technologies that enable them to exchange data over the internet or other communication networks

Question 2

IoT enabling technologies

Answer 2

• big data
• AI
• embedded systems
• cloud computing
• data analytics
• communication protocol
• wireless sensor network

Question 3

Features of IoT

Answer 3

1) network connectivity internet: at all levels (very close range = between devices, farther away = device-cloud, large distance)
2) things, sensors, and devices
3) intelligence, smart analytics
4) data, information
5) automation, decision, action
6) communication, data distribution
7) ecosystem community: main actors =
- sensing, embedded processing, connectivity
- smart devices, cloud computing, big data
- technology software apps
- users, groups of community

Question 3

IoT decision framework

Answer 3

it is a structured approach for powerful IoT products. it is divided in 5 layers of complexity of technology (IoT technology stack) and 6 key decision areas, each evaluated at each stack stage

Question 3

IoT technology stack

Answer 3

(layers of complexity of technology)
1) device hardware
2) device software
3) communications
4) cloud platform
5) cloud applications

Question 4

IoT decision framework: key decision areas

Answer 4

1) UX
2) data
3) business
4) technology
5) security
6) standards and regulations

Question 5

IoT architecture components

Answer 5

there is no universally defined standard, but there are 4 major components:
1) sensors / devices: LAN or PAN, sensors actuators (emit, process data), connected wire or wireless
2) gateways and networks; LAN or WAN, to transfer from sensors
3) cloud management service layer: Edge IT (= hardware and software gateways that analyse and preprocess data before sending it to the cloud), data center / cloud (data analytics + security controls)
4) application layer
