What IoT means:

The network of physical objects—devices, cars, appliances, and more—that are integrated with sensors, software, and other technologies to communicate and share data with other devices via the internet is known as the Internet of Things, or IoT. With the help of IoT, these “smart” things may gather, send, and act upon data, forming an intricate network of interconnected systems that can streamline workflows, improve efficiency, and yield insightful information.

What Embedded Systems Are:

Specialized computer systems called embedded systems are made to carry out particular functions in bigger mechanical or electrical systems. Embedded systems, as opposed to general-purpose computers, are specialized and frequently integrated inside devices to regulate and oversee their operation. Microcontrollers in microwave ovens, automotive engine control systems, and smart thermostat sensors are a few examples of embedded systems.

Connections Between Embedded Systems and IoT:

Many IoT devices are built on embedded systems. They supply the capability and processing power needed for gadgets to communicate online and engage with their surroundings. Essentially, embedded systems give devices the ability to be “smart” and involved in the Internet of Things. An embedded system, for instance, is used by a smart thermostat to track temperature, manage heating and cooling, and establish Internet of Things connections with other gadgets and online services.

Importance and Embedded Systems’ Impact:

The confluence of embedded systems and IoT has significant implications across multiple industries, ranging from healthcare and industrial automation to smart cities and households.
