The Internet of Things (IoT) refers to the network of everyday physical objects - such as home appliances, cameras, wearables, and industrial machines - connected to the internet. These devices collect, send, and receive data, often operating with minimal human intervention. IoT enables smart homes, efficient energy use, and improved automation in many sectors. However, because many IoT devices have basic security measures, they can be vulnerable to cyberattacks, making security an important consideration.
