The Internet has become an essential factor at the present time, not in one area of life, but in all different areas of life. And that the presence of the Internet is not limited to smart and electronic devices, but it is present in everything. The wide field of technology paved the way for a new stage in which devices are connected to each other without the need for human intervention, and this is what is known as the Internet of Things (IoT), and despite its development and widespread around the world, some may consider it ambiguous. Therefore, in this article, we will learn what the Internet of Things is and its advantages, in addition to the best “The internet of things applications” that facilitate life and shorten a lot of time.

What is the Internet of Things technology?

It is an advanced method for the Internet, which appeared in 1999 and was invented by the British scientist Kevin Ashton. It is abbreviated as IoT.

It is a modern technical method that transcends the way people communicate with smart devices over the Internet, as it allows people to communicate with smart devices without the need to be in a specific place.

The fact that IoT is a complex and challenging world that includes many programming languages and more is an integrated network system consisting of four basic components:

  • Sensors.
  • Connect to the Internet.
