What Is the Internet of Things (IoT)?

Internet of things, or IoT, is a network of physical objects that has sensors, software, and other technologies for connecting and exchanging data from one device to other devices or systems via the internet.

To explain this concept of IoT, let us consider an example. Suppose you read an article on the internet. It could either be through a desktop, laptop, mobile or a tablet. Now, how is it possible that we can read an article through these devices? The answer is simple. These devices are connected through the internet that facilitates reading articles.

IoT is quite a simple concept. It means connecting devices to the internet to derive significant benefits.

What are IoT devices?

IoT devices are the smart devices that support internet connectivity and can interact with other devices over the internet.

These devices include:

  • Smartphone
  • Smartwatch
  • Smart home
  • Smart door lock
  • Connected cars
  • Smart security system and many more.

History of IoT

The concept of IoT was first discussed in 1982 with a modified soft drink vending machine, which became the first internet-connected appliance that was able to tell whether the loaded drink was cold or not.

Rexa Raji, in 1991,  introduced the IEEE Spectrum concept as moving tiny data packets to a big set of nodes to incorporate and automate each and everything from home appliances to overall factory. Kevin Ashton of Procter and Gamble coined the term Internet of Things in 1999.

The driving force behind IoT is the metal-oxide-semiconductor field-effect transistor, also known as MOS transistor, which was initially invented in the year 1959 at Bell Labs by Mohamed M. Atalla and Dawon Kahng.

For information, a metal-oxide-semiconductor field-effect transistor is the building block of most of the electronic devices in the present times like computers, smartphones, internet devices and many more.

In the 21st century, the scaling of  MOS transistor has been extended with advancement to reduce power consumption silicon-on-insulator semiconductor device fabrication, plus multi-core processor technology. It has resulted in IoT, which is being driven by the scaling down of MOS transistor to nano electric levels with lessened energy consumption.

How does IoT work and what makes them smart device?

There are two simple things that can convert a standard device to a smart device.

  1. The capacity of the device to connect to the internet.
  2. The devices which get connected with sensors, functional software, inbuilt technology support network connection as well as actuators. An actuator is a machine component that moves plus controls the system.

Once these functionalities are well combined, an IoT device is formed. A simple example of this is a smartwatch. Smartwatch not only tell you the time, but it also helps to track your health like a heartbeat, pulse etc. Some smartwatches alert the user about any phone calls as well.

What are the advantages and disadvantages of IoT?


While there are various advantages of IoT devices. Some of them are as below:

  • IoT allows machine-to-machine interaction.
  • It provides good automation and control.
  • When IoT gets integrated with more technical information, it can be operated in a better way.
  • IoT saves a lot of time, money and eliminates manual effort.
  • Improves efficiency.


Despite so many favourable features of IoT, there are a few disadvantages as well. They include:

  • The IoT devices do not have any international compatibility strength.
  • In case of any failure, IoT devices may become very complicated.
  • There are chances that IoT devices might get impacted because of privacy and safety breach.
  • With the increased usage and reliance on IoT devices, it may be possible that IoT can control one’s life in the upcoming period.

What has made IoT so important amongst people?

IoT has been amongst the most important technologies in the present times. Not only for household or daily uses purposes, but IoT also has not started gaining grounds at industrial levels. Various industries have now started adopting IoT technologies to improve their efficiency.

This innovative technology not only connect devices to the internet, but it also provides users other features like real-time analytics, cloud data storage, trigger action from a remote location, remote notification etc.           

What Technologies have made IoT possible?

IoT has come into existence with the recent advancement in technology. Let us look at them one by one.

  • Affordable and Reliable sensors: It is because of the availability of affordable and reliable sensors, it has become possible for the manufacturer to make IoT technology.
  • Connectivity: A host of network protocols have made it possible to connect sensors seamlessly to cloud and other things so that the data gets transferred efficiently.
  • Cloud Computing Platforms: The improved availability of cloud computing platforms has made it possible for businesses and customers to access the infrastructure without worrying about how to manage it.
  • Machine Learnings and Analytics: With the advancement in technologies like machine learning and analytics plus access to data stored on the cloud, it has become feasible for the business to retrieve an extensive data set at a faster rate and more efficiently. The emergence of these technologies has given a chance to IoT technologies to expand more.
  • Conversational Artificial Intelligence: Advancement in neural networks have enabled natural-language processing to IoT devices and made it possible and affordable for home applications. The beat and the most common example of this Alexa and Siri.

Business Value with IoT

IoT in the present times have become more and more widespread, and various companies are capitalizing on the huge business value it can provide. Some of these are:

  • Obtaining data-driven visions from IoT data for managing the business.
  • Another vital point about IoT is that it improves business productivity and efficiency of business operations.
  • It also helps to create a new business model and would generate new sources of revenue stream.
  • It helps to connect the physical world to the digital world.
