The advanced form of embedded systems with some modifications tends to the term IoT, which enables the hardware devices to get live for a specific time as per the program.IoT is one of the leading advanced technology used now a days. Which can operate such hardware devices from a long distance or anywhere in the world, just with an internet connection .Which is the main feature of the technology .The Internet of Things has arrived and it’s going to introduce incredible opportunity over the next five years. And while smart things are exactly that, the IoT industry has a long way to go in terms of overall security. Many of today’s IoT devices are rushed to market with little consideration for basic security and privacy protections.In the most general terms, the Internet of Things includes any object – or “thing” – that can be connected to an Internet network, from factory equipment and cars to mobile devices and smart watches. But today, the IoT has more specifically come to mean connected things that are equipped with sensors, software, and other technologies that allow them to transmit and receive data – to and from other things. Traditionally, connectivity was achieved mainly via Wi-Fi, whereas today 5G and other types of network platforms are increasingly able to handle large data sets with speed and reliability.
