Internet of things for beginners
The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity—that enables these objects to collect and exchange data.
The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT)
IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit.
In simple words,Internet of Things(IoT) is an ecosystem of connected physical objects that are accessible through the internet.
It is also referred to as Machine-to-Machine(M2M),Skynet or Internet of Everything.
The concept of the Internet of Things first became popular in 1999,through the Auto-ID Centre at MIT and related market-analysis publications.
Radio-frequency identification (RFID) was seen as a prerequisite for the IoT at that point. If all objects and people in daily life were equipped with identifiers, computer cloud manages and inventories them. Besides using RFID,the tagging of things may be achieved through such technologies as near field communication,barcodes,QR codes,bluetooth,and digital watermarking.
How IoT Works?
Internet of Things is not the result of a single novel technology; instead, several complementary technical developments provide capabilities that taken together help to bridge the gap between the virtual and physical world.
These capabilities include:
- Communication and cooperation
- Embedded information processing
- User interfaces
Components of IoT
Smart Systems and Internet of Things are driven by a combination of :
- People and Processes
Why IoT ?
- Dynamic control of industry and daily life.
- Improves the resource utilization ratio.
- Integrating human society and physical systems.
- Flexible configuration.
- Acts as technology integrator.
- Universal inter-networking.
