IoT is another promising emerging technology trend. Many “things” now have Wi-Fi connectivity, allowing them to link to the Internet and to one another. As a result, the Internet of Things, or IoT, was born. The Internet of Things is the wave of the future, and it has already allowed computers, home appliances, vehicles, and much more to link to the Internet and share data.  We are already using and taking advantage of IoT as users. We can lock our doors remotely if we fail to do so before leaving for work, preheat our ovens on our way home from work, all while keeping track of our health with our smartwatches. Businesses, on the other hand, have a lot to gain right now and in the near future. As data is collected and analyzed, the IoT will help businesses improve their safety, performance, and decision-making. It has the potential to allow predictive maintenance, enhance medical care, and provide benefits we have not even considered. And we are just at the start of this emerging technology trend; estimates say that by 2030, about 50 billion IoT devices would be in use around the world, resulting in a huge network of interconnected devices ranging from smartphones to kitchen appliances. In 2022, it is anticipated that global spending on the Internet of Things (IoT) will cross 1.1 trillion dollars. If you want to work in this lucrative field, you will need to learn about information security, AI and machine learning basics, networking, hardware interfacing, data analytics, automation, embedded systems understanding, and computer and design knowledge.
