What Is IoT?
Welcome to another article by techitcs.com. Today I will tell you everything that you need to know about the Internet of Things. So let’s start…
I hope that you read my article “what is a networking” if not then go and check it out.
In my previous article, “what is networking” I explained you the entire process how devices are connected and I also explained to you how they communicate with each other with the help of IP addresses.
The term IoT stands for Internet Of Things where billions of devices are connected to each other all around the globe. All devices are communicating with each other and transferring data electronically.
It’s all possible just because of cheap and small computer chips.
Using IoT you can control something as big as aeroplane by using something as small as a pill. We can give these dumb devices a life by adding some sensors and a level of digital intelligence. By connecting some sensors we can enable these devices to communicate real-time data without involving a human being. Imagine how life will be when there is no need to do anything the devices communicate with each other transfers the data and take the appropriate action.
Where Internet Of Things is being used now?
Any physical device can be transformed into an IoT device if it can be connected to the internet.
Have you seen the lightbulb that can be switched on and off using smartphone App same is for motion sensors that can transfer information if it senses any kind of motion.
Some big objects contain thousands of smaller IoT components.
IoT enables the devices to communicate with each other and take an action that it is supposed to take. Devices that can’t be connected to the internet can be connected with the internet using some sensors. So that they can communicate without any human intervention. Like s smartwatch or a fitness band or any other device.
History of the Internet of Things?
The idea of connecting devices together by adding sensors and intelligence came in the 1980s. A very famous project of that time was an internet-connected vending machine. The technology was not so evolved at that time, as a result, slow responses and big bulky machines since the size of the chips were not as small as today. After some time a new technology is developed that is known as RFID.
What Is RFID?
RFID stands for Radio Frequency Identification. RFID tags are the low power consumption chips that are able to communicate wirelessly. But you know as I explained in my previous article that due to the huge world’s population we adopt IPv6 – Internet Protocol version 6 before that we had IPv4 you can read my article about IPv4 and IPv6 there I explained how all these works. So let us come back to IoT…
These RFID tags use electromagnetic fields that help us to identify and track tags attached to an object. Adding these tags to expensive objects helps us to track their location this was the first IoT application.
What are the benefits of Internet Of Things for the industry?
IoT is huge. By using IoT in your home or office you can be free from a lot of hassle. By adding IoT to your life you can automate the regular tasks in your day to day life. A lot of manufacturers are adding sensors to their products so that they can transmit the data about their performance. This process helps companies to predict when a component is likely to fail so that it can be replaced before it causes any kind of damage. The data sent by these sensors is also helpful for the companies to make their supply chain more efficient because they are now with real-time and more accurate data.
Benefits of IoT for consumers?
IOT provide us with a way through which we can make our day to day tasks easier by connecting different devices together so that they can communicate and give a fruitful result without the involvement of human being. Smart speakers like Amazon’s Echo and google home make it easier to play music and it can also control the home lights if they are compatible with the device. Home security system is equipped with IoT so that it can make your houses more secure even if you are not there. There is a smart thermostat that can heat your home before you come back and the smart light bulbs that will automatically switch off when there is no motion and can be controlled by a simple mobile app.
Cybersecurity for IoT
There is no doubt that anything inside a network can be hacked easily if you do not pay any attention to it. Security is one of the biggest issues with this technology. The sensors that are used in IoT devices collect extremely sensitive data like what you say and what you do in your home. But so far the IoT security track is extremely poor. The IoT devices have software which makes them intelligent and we all know that software can be easily hacked that make your entire data vulnerable. Hackers always try to hack these IoT devices by which they can gain access to your private data. A team of researchers found that there are approx 100,000 webcams that can be easily hacked and also some internet-connected smartwatch have been found with vulnerabilities that allow hackers to track your location.
Everybody is aware of the risks that are involved with the use of IoT devices. There are several guidelines that are published by the UK Government for the security of consumers. All the devices should have a unique password, not that same password that is provided by the company.
Although IoT bridges the gap between the digital world and real-world but the risk of getting hacked is always there.
IoT and Big data
Imagine the amount of data that can be collected by these small IoT devices. These device includes your door lock codes, what you prefer, and everything that you know and share with IoT devices. This huge data can be used in various ways to determine what people like and what they don’t like. And with that information, a company can develop its products.
