Internet of Things Interview Questions

Introduction

IoT, referred to as the Internet of Things states the overall network of interconnected devices and the technology that enables interaction between them and the cloud. We now have billions of gadgets connected to the internet due to the development of low-cost computer chips and high-bandwidth telephony. The statement implies that common gadgets like vacuum cleaners, cars, and robots might employ sensors to gather data and respond wryly to consumers.
