Internet of Things (IoT) involves connecting everyday devices to the internet to extract meaningful data and integrate greater computing abilities. As more devices become "smart" and connected, a system of interconnected devices is formed. For example, connected cars and parking meters can share data to guide drivers to available spaces. Popular trends in IoT include smart watches that sync with calendars and notifications, traffic camera systems that advise alternate routes during accidents, and online payment services that securely transfer accounting data. ATMs are also an example of interconnected things that provide real-time transaction notifications for security.
