Internet of Things| Advantages and Disadvantages of IoT_ Shifa Tariq

Updated: 15 Mar 2022



Internet of Things is a system of interrelated computing devices that are embedded with software, processors, communication hardware, Digital machines, sensors, and many other technologies for connecting and exchanging data with other devices over the internet. If we connect all these computing devices and add sensors to them then it adds a digital intelligence to physical devices. IoT can transfer data over the internet without involving humans and other computer interactions.

Advantages of Internet of Things
  • Enhanced Data collection
  • Efficient and saves time
  • Minimize Human efforts
  • Improved Productivity
  • Security


 Advantages of the Internet of Things:

The Internet of things facilitates several advantages in our regular routines. Some of its advantages are given below:

  • Enhanced data collection:

The most important benefit of IoT is enhanced data collection which means you can easily access data and information, even if you are far away from your actual location. This is possible because of computing devices; a person can access data and information at once instead of waiting till the end from any part of the world. Hence, with IoT, every problem gets solved instantly.

  • Efficient and saves time:

Reducing human efforts saves our time. So saving time is the primary factor in using IoT platforms. If we know the functionality and how each device works, we can increase resource utilization and monitor natural resources.

  • Minimizes Human efforts:

It minimizes human effort because IoT devices interact and communicate with each other. They can automatically do their tasks without the need for human inventions.

  • Improved productivity:

Another great advantage of IoT is its increased productivity. IoT allows you to monitor your products 24 hours. In case of a malfunctioning device, you can take immediately action to solve the issue.

Also if you are getting instant feedback, you can make changes according to the present situation. So you can save both money and resources.

  • Security:

We can make the system more secure and efficient if we have an interconnected system. It can assist in the smarter control of personal data and information through mobile phones.

The IoT is big news because it ups the ante: ‘Reach out and touch somebody is becoming reach out and touch everything. Parker Trewin

Disadvantages of Internet of Things
  • Complexity
  • Compatibility
  • Increased unemployment
  • Security issues
  • Lack of international standardizations

Disadvantages of the Internet of Things:

As the IoT works with many benefits, it additionally creates a huge arrangement of Disadvantages. Some of its cons are given below:

  • Complexity:

The designing, developing, maintaining, and enabling of the broad technology of the IoT framework is quite complicated.  As we know IoT is what different organizations that associate with different devices. A single error can affect the entire system. This is a more complicated aspect of the Internet of things that can have a huge impact on work.

  • Compatibility:

 The devices from distinct makers will be interconnected to one another so there’s the problem of similarity in tagging and tracking increments. There is a risk that the technical troubles may additionally persist, even if manufacturers make a commonplace well-known. Compatibility issues nonetheless exist despite the reality that we've got Wi-Fi devices. Compatibility troubles would possibly bring about people shopping for devices from a change manufacturer, prompting its enforcing commercial enterprise model looking out.

  • Increased unemployment:

With each project being computerized, unskilled and also skilled workers are at the risk of losing jobs. Smart devices like robots, cameras, computers, digital washing machines, and many other facilities are replacing humans to make work easier and faster. All this will have a direct impact on unemployment. As we head into the fate of IoT, there will be a noticeable decrease in the hiring system of experts.


  • Security issues:

In the present tech-driven world, every single device is interconnected and communicates with each other over the internet. So there is a risk of leakage of information that can be misused. That’s why a lot of people feel uncomfortable while sharing information on the internet. It is a major drawback of sharing information because it might not be safe & could be hacked by third parties easily.

  • Lack of international standardizations:

There is no international standardization among different manufacturers.  Each organization develops its proprietary arrangements which make things difficult for people to choose which one is best for them in these various options.  Hence, there is no common standard for data collection and transmission over computing devices which makes it hard to integrate various frameworks into one organization.


There are a few disadvantages of IoT, but its advantages of saving the consumer time and money can’t be ignored.  So the time isn't far when the Internet Of Things will be regularly seen in houses and organizations.
