 Definition of IoT

IOT  mean "Internet of Things." It refers to a network of physical devices, vehicles, buildings, and other objects that are embedded with sensors, software, and network connectivity that allows them to collect and exchange data over the internet. The IoT is aimed at creating smart systems and environments where devices can communicate with each other, automate processes, and provide valuable insights into their performance and usage patterns.A few normal instances of IoT gadgets incorporate savvy home machines, wearable wellness trackers, modern sensors, and independent vehicles.

History of IoT.

                                                

The Internet of Things is a term that alludes to the organization of actual items or "things" installed with sensors, programming, and different innovations that empower them to interface and trade information with other devices and systems of the internet.  While the concept of IoT has gained popularity in recent years, its origins can be traced back to the early days of computing.

The first internet-connected device was a toaster that was connected to the internet in 1990 by John romkey, a computer programmer. However, it wasn't until the late 1990s that the term "Internet of Things" was coined by Kevin Ashton, a British technology pioneer. In a presentation to Procter & Gamble, Ashton used the term to describe how everyday objects could be connected to the internet and exchange data with each other.

One of the first practical applications of IoT was in inventory management. In 1999, the Massachusetts Institute of Technology (MIT) developed the first Radio-Frequency Identification (RFID) technology that allowed retailers to track their inventory in real-time.  This technology was later adopted by Walmart in 2003, which made it mandatory for all of its suppliers to use RFID tags on their products.

In the early 2000s, the growth of wireless networks and mobile devices paved the way for the development of more sophisticated IoT systems. In 2003, the University of Cambridge launched the first fully functional IoT platform, which was used to monitor the energy usage of its buildings. Around the same time, the European Union launched a research program called the Internet of Things Initiative, which aimed to explore the potential of IoT in various fields, such as healthcare, agriculture, and transportation. 

By the mid-2000s, IoT was gaining traction in the consumer market as well. In 2007, Apple launched the iPhone, which paved the way for the development of mobile apps and connected devices. In 2008, the first smart thermostat, the Nest Learning Thermostat, was launched, which allowed homeowners to control their home's temperature remotely using their smartphone.  In 2010, Fitbit launched the first wearable fitness tracker, which allowed users to track their physical activity and monitor their health.

In recent years, IoT has become increasingly popular in industries such as manufacturing, healthcare, and transportation. In the manufacturing sector, IoT has been used to monitor production processes and optimize supply chains. In healthcare, IoT has been used to monitor patients' vital signs and improve the delivery of medical care. In transportation, IoT has been used to improve the efficiency of logistics and reduce the carbon footprint of vehicles.

However, the growth of IoT has also raised concerns about privacy and security. As more devices are connected to the internet, there is a risk that they could be hacked or compromised, leading to data breaches and other security issues. In addition, the vast amount of data generated by IoT devices raises questions about how this data is collected, stored, and used.

Despite these challenges, the future of IoT looks bright. According to a report by McKinsey, the economic impact of IoT could reach $11.1 trillion by 2025. As IoT technology continues to evolve, it is likely that we will see new applications and use cases emerge, transforming the way we live and work.
