Study Notes
Digital Transformation
- More smart devices exist than people.
- By 2030 each person will have 15 smart devices.
- Modern digital networks make this possible by connecting devices and creating a platform for innovation.
- Digital transformation uses technology to drive business innovation.
Smart Devices
- If programmed correctly, smart devices can analyze data, modify processes and settings.
- They can learn and modify their own code based on new parameters.
- Smart cities use sensors to control infrastructure like traffic flow, parking, water usage and hydro.
- Self-driving cars are equipped with various sensors, cameras, GPS and computers.
Networking
- 50 billion devices provide trillions of gigabytes of data.
- Networks provide the foundation for the internet and the digital world.
- Networks can range from simple to complex connecting millions of devices.
- Networks connect to the internet to deliver products and services to customers.
Internet of Things (IoT)
- Millions of smart devices and sensors connected to the internet.
- Previously non-smart objects like doorknobs and light bulbs can now be equipped with sensors to collect and transfer data.
- 3 million new devices connect to the internet monthly.
- Over 50 billion connected devices worldwide are expected in the next 4 years.
- Two-thirds of those devices will be sensors, actuators and intelligent devices that monitor, control, analyze and optimize our world.
Connecting IoT Devices to the Network
- Sensors gather data that needs to be connected to a network for storing and sharing.
- Controllers are responsible for processing data and making decisions.
- Actuators take action based on the controller's decisions.
- Communication technology connects all elements and facilitates data transfer.
