The Internet of Things (IoT) | What is IoT | How it Works | IoT Explained |

The second hot topic in today’s world revolves around the Internet of Things, whose acronym is ‘IoT’. The appliances we use in our daily life – AC, coffeemaker, temperature control, fan, TV, door lock, car garage door, car, and so on – are just one way of controlling the Internet sitting anywhere in the world with your ‘Internet of Things’. Being called ‘IoT’. Of course, this is not just the case in the middle of the house, but the biggest area of ​​IoT can be any industry. Professor Michael Wang of Columbia University in the United States has shown in his study that if IoT use can be ensured, up to 90 percent of our garment fire accidents can be avoided.

What is the Internet of Things or IoT?

The Internet of Things collects the necessary information on various devices on a particular network through the sensor network of different devices and uses the various means including wire communication, radiofrequency, serial communication, serial peripheral interface to analyze the information on a local processing device, such as a laptop or smartphone. Various Communications Pr Transfer to the specific web server or cloud computing server using tokens like HTTP, MQTT, Wi-Fi, Bluetooth, etc. This information is stored in the database on the system. Data analytics is used to process commands available from different sensors, and filter the results from the system. Dependent other systems are handled at the same time. Since all the process is dependent online, sending commands to the system can be done anywhere, from controlling the device or the environment, from visualizing the status to on and off.

What is the Internet of Things (IoT)?

Things we will discuss here-

Internet-connected devices, we still understand our PCs, laptops, tablets, smartphones. But with the advancement of technology, many other things are now becoming connected to the Internet. These are called smart devices. Surprisingly, the Internet is connected to TVs, fridges, cars, even door locks.

In the sense of the IoT, all devices will have one IP address. IPv6 will do this. As a result, different devices on the same network will be able to interconnect themselves.

We all know about human endeavors to create intelligent machines through Artificial Intelligence. IoT research is not new. The cookie machine was invented at Dell Carnegie Mellon University in 1980. Through the Internet, the machine itself could make some decisions, such as whether the machine had a drink or whether it was necessary to make the trip. Kevin Astre of MIT first introduced the word IoT in 1999. In an interview in 2009, he explained his views on the future of IoT and also highlighted its large market value.


Business Intelligence will create a new market of US $ 1 trillion in hardware, software, management, servicing and other fields for the capacity of IoT over that period. By the end of the year 2025, 10 million devices will be on the market, of which sales will only be around the US $ 5 billion. Profit from hardware will be only 8-10% of profits from IoT.

What is the Internet of Things (IoT)?

The Internet of Things is abbreviated as IoT, which means connecting the Internet to different things. With the help of this technology, we can access various electronic devices such as TVs, fridges, lights and connect them to the Internet from anywhere.

What is the IoT component?

The IoT components are –

  • People
  • Infrastructure
  • Things
  • Process
  • Data

People: People are people who use IoT devices.

Infrastructure: Infrastructure is an Internet connection.

Things: Things are the devices that will stay connected. For example, a camera, TV, refrigerator, etc.

Process: The way these things are connected.

Data: All data in this process is stored. For example, Hadoop.

IoT applications

IoT applications that are used most often.

  • Manufacturing
  • Healthcare
  • In the field of education
  • In terms of creating a digital city
  • Security
  • Medical
  • Transpiration
  • Hospital
  • In the case of room automation, etc.
  • IoT Case Studies

IoT Deployment in Singapore: Singapore was declared as the smart city in 2014. Displays the speed of a car when driving on the streets of Singapore.

IoT Deployment in Barcelona: Smart lights and sensors have been installed in Barcelona. As a result, the light goes on without detecting any motion.

San Francisco IoT Deployment: Launches the smart parking system in San Francisco in May 2011. As a result, one can easily know where to park the car nearby.

IoT Deployment in Bangladesh: IoT has been deployed in agriculture in Bangladesh. As a result, it is easy to know if there is any problem with the crop

IoT Security

It was once thought that as IoT devices are small these hackers usually do not come to hack. But this idea was wrong. Now, IoT devices are a big target for hackers. So firewalls, IDs, IPs are used to protect these devices.

What are the most common attacks on IoT?

  • Deeds Attack
  • Worm Attack
  • Voice and Sound Attack

Deeds Attack: Deeds Attack is a Distributed Denial of Service Attack. Typically, this type of attack is similar to attacking from different places simultaneously.

Worm Attack: The major disadvantage of a warm attack is that such an attack spreads all over the place. For example, if a light bulb is attacked, the effect will be on the city’s light.

Voice and Sound Attack: Most IoT visuals have sensors as well as a microphone built-in. The audio beacons can be easily captured through audio beacons.

  • How to protect IoT devices from hackers?
  • IoT devises firmware should always be updated.
  • Voice Detect software should be turned off when not in use.
  • The encryption method must be used in communication.
  • Anti-deeds should be used.
  • Authentication must be deployed between IoT devices and only trusted devices can communicate.

The advent of something new in the world of technology means it’s time to start the culprit’s trial. As the blessings of the IoT say, when a lot of information is in handheld, making the best decision will be easy. Again, more monks may lose erosion. If industrial automation is ensured, costs will be reduced, productivity will increase, product quality will increase, work will be accelerated. At the same time, the dependence of the human-machine will destroy its creativity, efficiency, as well as in many cases the machine will occupy the human space. At the same time, as many will enjoy the benefits, the security or privacy of something can be deadly. Which in the end can overwhelm all successes? If the unit does not have a controller, it can also have adverse effects on mobility.

But as technology’s excellence cannot be stopped, there is no doubt that the Internet of Things or IoT will be a blessing to us.

Finishing here as it is today. I can share the text. Good luck to everyone !!
