The Internet of Things (IoT) involves a huge network of linked physical devices that contain sensors, computer-programmed software, and access to the internet and gather, share, and take action based on the information. It is revolutionary in all the fields including healthcare, agriculture, industry, and smart cities, as it increases automation and decision-making. IoT allows working in real-time and predictive analytics, making operations more efficient and pleasant to use. Although it has so many advantages, it is concerned about data privacy, security, and interoperability. IoT in the future relies on more sustainable, secure, and intelligent distribution amongst industries.

Key Points for RAS Mains

What is IoT?

• The Internet of Things (IoT) consists of an interconnection of physical entities that are built with sensors, software, and communications.
• These devices gather information in real-time, disseminate the information on the internet and on many occasions, they operate on the information automatically with no human interaction.
• Its aim focuses on automation of systems, increasing productivity, cutting down the cost of operation and improvement of living standards.
