Internet of Things (IoT)

What is IoT?

IoT primarily refers to any device, appliance, instrument, or machine that can connect to the internet.

How does IoT work?

IoT devices contain sensors and mini-computer processors that gather and collect data via machine learning. These data are collected through a Wi-Fi or secure LAN connection. Picture a smart vacuum that can clean on its own and can be controlled remotely through your phone. Or a door with a built-in smart camera that alerts you when someone tries to get in your home.

What is IoT used for?

IoT devices are combined with sensors that transform normal objects into smart devices with a level of digital intelligence that can communicate with each other and exchange data in real-time.

Amazon’s Echo is a good example of what an IoT device can do to home appliances. After it has been set up to your account, it can do your shopping for you, switch your lights on and off, play some music for you automatically, set an alarm for you, set reminders, all the good stuff.

IoT is not only limited to consumer devices and applications though. There are also the game changers such as industrial and commercial IoT. We are talking about self-driving cars that communicate with each other and to the road, constantly sharing and exchanging data. To keep traffic flowing, IoT can calibrate how closely automobiles follow each other based on multiple variables surrounding them.

What are some examples of IoT devices?

There are home devices like light bulbs, electric plugs, coffee machines, toilets, bathrooms, TV, washing machines that can be connected to your home Wi-Fi so you can control them remotely using your phone.

There are also smart city IoT solutions such as environmental monitoring (weather, air quality, flood, and pollution), traffic monitoring, connected public transport, and smart lighting.

Advantages of IoT


IoT can collect and monitor data that allows users to keep track of things through their phones.


IoT allows users to gain required information in real-time. It can also be accessed and controlled remotely.


Multiple data that needs to be processed can be automated with great speed thanks to IoT. In a business setup, this decreases the need for employees to invest their time and effort on things that can be solved by IoT.


IoT makes complicated tasks easier and more convenient by automating various tasks that would otherwise take a long time to complete.

Disadvantages of IoT


Desperately need to switch the lights off while you get ready for bed but no internet connection? Too bad! No internet eliminates the “smart” function on that smart device.

Data breach and other security risks

IoT can be used as an entry point into your network, resulting in data breaches, hacking, information theft, botnets, and other IoT-based attacks.
