Evolution of IoT(Internet of Things)

IoT(Internet of Things):

Internet of Things is a real-world thing around us is able to(Machine to Machine) communicate, sense and interact with other things those are creating a network of things are known as “Internet of Things”.

Evolution of Internet of Things:

Nowadays industries or factories are growing very fast like manufacturing industries were lots of machines and manpower used for the best quality products. In these machines, are were monitored and controlled by Microcontrollers. Microcontrollers can be considered a self-contained system with processor, memory and its devices.

In microcontrollers had limitations with the number of inputs it can work with and how many outputs it can trigger so then provided one process that is Programmable Logic Controller (PLC). It is an industrial computer used for controlling the process.

Programmable Logic Controller works divided into four core areas :

1) Rack and Power supply

2)CPU(Central Processing Unit)

3)I/O section (Input/Output)

4)Program section

These are a little bit take time and human interventions are needed. So the technology advancement in manufacturing processor into smaller integrated circuits (IC) with power and larger memory for storing purpose. It rises into Embedded Systems. Embedded systems are range from portable devices such as digital goods.

Embedded systems are made machines powerful, robust, quality and efficient, the machines are isolation but not communicate with each machine. So we need to communicate between two or more machines(Things) into a well-managed network(Internet or Intranet).

The Internet of Things is the network of physical devices, machines, vehicles, etc items are embedded with sensors, software and actuators are, etc.

Summary: Internet of Things is a type of Embedded system that connects through the internet. Internet of things may be updated constantly with new features and quality and efficient but not in Embedded systems this is the smaller difference between them.
