"The IoT market reached $761.4 billion in 2020 and is expected to reach $1.39 trillion by 2026, according to Mordor Intelligence." If you are looking for a safe job in the future, then it is worth learning IoT stuff. Another important field is AI/Machine Learning (Data Science) for the future. I have decided to write this year a series of articles about IoT. I will cover all the stuff that can make you an Azure IoT Expert (Development and Architecture). I will start with the basics and connectivity and continue until the user interfaces and reporting.

One of the world's most disruptive industries is voice services. Once dominated by a few large and established players, new innovations in Internet Protocol (IP) communication technologies are making it easier for non-telecom businesses--including software and hardware companies--to compete effectively. To be successful, however, it's not enough for these challengers to have a great idea. They must also be able to focus their efforts on what they do best and get their solutions to market quickly. Level 7 Systems is one such startup.

A communications test was performed in 1975 between Stanford and University College London for what was to become arguably the most important communication innovation of the 20th century: The Internet Protocol (IP). At its core, IP was focused on speed and simplicity. This required decentralization of ownership of the "web" and resulted in no one owning the Internet, nor the controls and routes used to transmit it. While there are 75 million servers running the global Internet, there are 1.2 billion cars driving global transportation, with 253 million in the United States alone (the highest per capita rate of any large country). Personal vehicle ownership is grossly inefficient: Cars are estimated to be parked 95 percent of the time.
