List and describe technologies that enable the IoT.
What will be an ideal response?
The IoT brings together several recent technology developments. Communications technologies, such as Bluetooth, RFID tags, near-field communications (NFC) tags, and sensors tracking heat (temperature), light, weight, or location have become readily available. Sensors and tags can transmit messages to a server on the Internet over a wireless network at frequent intervals for analysis and storage. Developments in Big Data have made it possible to access, store, and process all of this data reported by sensors efficiently. Mobile service providers offer connectivity to a variety of devices at broadband speeds, so transmitting and retrieving data can take place quickly. The size and cost of wireless radios has decreased, enabling more things to have embedded sensors, tags, and transmitters. The capability of computers, devices, and everyday objects to communicate with one another over the Internet has opened new possibilities for both consumers and the enterprise to be more productive, efficient, and informed.
