Smart devices are electronic gadgets that connect, interact and exchange data with other systems or networks via different connectivity methods. They typically offer digital services, automate tasks, and improve the user experience. Some smart devices are everyday objects that previously lacked electronics and are now equipped with sensors, while others are designed to interact directly with humans, such as smartphones or fitness trackers.
Many smart devices run on a real-time operating system (RTOS) or an embedded Linux platform, which are more suited to the high-speed processing needs of modern digital technology. Others use a microcontroller to perform complex operations within a small mechanical or electrical system, like controlling the movement of a smart doorbell’s camera. Smart devices also communicate with other devices and the cloud using a variety of connectivity protocols, including MQTT, Zigbee, and Z-Wave.
As smart devices become more pervasive in our lives, they can generate large amounts of data and require extensive computational power to process them. This data can be accessed by unauthorized individuals, used for cyber attacks, or sold to marketers. Fortunately, consumers can take steps to reduce their exposure to smart device data.
For example, they can change the default username and password or disable features that aren’t required, such as Bluetooth, GPS or mapping capabilities. It’s also important to keep all your devices updated, as manufacturers release updates that fix bugs or security issues. Leaving your devices with outdated software could make them easier to hack or even stop working altogether.
