Embedded System are combination of Software and Hardware circuit. In that embedded designing of electronics circuits with the help of tools and with the help of software that electronics circuit turns into dedicated product as per our requirement.
System is a controller with a dedicated function within an larger mechanical or electrical systems often with realtime computing constraints. An Embedded System is a dedicated computer system designed for one or two specific functions. Embedded System are manage by single or multiple processing cores in the form of controllers or digital signal processors, application specific integrated circuits and gate Array.
The IOT involves extending internet connectivity beyond standard devices, such as desktops, laptops, smartphones and tablets, to any range of traditionally dumb or non-internet-objects. Embedded with technology, these devices can Communicate and interact over the internet, and they can be remotely monitored and controlled Internet of things basically refers to network interfacing and communication of physical objects, devices and peripherals which can communicate and exchange information between each other without depending on human to human to computer interaction.
“Things” in the IoT sense, is the mixture of hardware, software, data, and services. “Things” can refer to a wide variety of devices such as DNA analysis devices for environmental monitoring, electric clamps in coastal waters, Arduino chips in home automation and many other. These devices gather useful data with the help of various existing technologies and share that data between other devices. Examples include Home Automation System which uses Wi-Fi or Bluetooth for exchange data between various devices of home.
