The Internet of Things (IoT) refers to the network of everyday physical devices - such as smart thermostats, wearable fitness trackers, home security cameras, and even appliances like refrigerators or coffee machines - that are connected to the internet. These devices collect and exchange data, often operating with minimal human intervention, to improve convenience, efficiency, and automation in daily life and business. However, because many IoT devices have limited security features, they can be vulnerable to cyberattacks, potentially exposing personal data or providing entry points for hackers into larger networks.
