The full form of IOT is "Internet of Things". It is a vast network of people and devices at the same time. Internet of Things (IoT) refers to a system of interconnected and Internet-connected objects. In this particular method data or information is collected and transferred through a wireless network without any human intervention.

The devices included in this network collect, share, and use this data according to environmental conditions. The “Internet of Things” or IoT has changed everything in our daily lives. The "Internet of Things" is a concept where smart electronic devices are connected to each other through the Internet and are able to automatically communicate or exchange information and make decisions based on information analysis.

"Things" in Internet of Things means objects. These "things" are basically smart electronic devices such as cameras, TVs, refrigerators, lights, audio systems, washing machines, etc. IoT is now being used in football as well. Sensors in football measure how fast the ball is kicked or how far the ball travels. Then a record of all the data is kept for training the players. Again the smart microwave oven can be connected to IoT for how long the device needs to heat a food. These can be determined automatically by sensors.

The function of the sensor is to monitor the movement of people or any object and give the necessary information and process it and send it from one device to another device. This is how an IoT system works. But the fact is that these new smart devices can be connected to the Internet as a result of improvements in networking technology.“Each of the Things in the Internet of Things takes information from its surrounding environment with the help of sensors. A sensor is a widely known device. It acts as a converter.

That is it can convert any environmental change into an electrical signal. It can respond to sound, heat, light etc. Computer systems are connected with electronic devices to automate various necessary devices or items. Also any type of electronic device can be connected to IoT. At least devices that can be turned on and off can be covered by IoT. The Internet of Things mostly uses the Internet. The Internet of Things (IoT) does not always require the Internet. In today's digital landscape devices, machines and objects of any size can automatically transfer data over a network. At the same time this method can effectively communicate with each other in real time. Internet of Things has made our daily life easier than ever.

This modern approach is reinventing the world in ways we could never imagine before. Also it has become an integral part of our daily life in this digital age. This remarkable concept has connected us virtually everywhere through smart devices. The Internet of Things basically refers to the interconnection of everyday devices. From smartphones and laptops to appliances and vehicles all are connected to the Internet and able to communicate with each other. This technology is revolutionizing industries from healthcare to transportation.

Today this method has the potential to greatly improve our daily lives. The role of IoT is immense in making people's lives easier. Using this technology, sitting at one end of the world, various devices such as light-fans, washing machines, air-conditioning systems, CCTV cameras etc. can be controlled with the help of smartphones. In the era of modern information technology the global Internet of Things is now a very big and promising technology. The adoption of IoT has increased manifold in recent years.

The main reason behind this is that consumers and organizations have already started reaping its benefits. According to a study the number of connected IoT devices in the world will exceed 75 billion by 2025. IoT applications are mostly used in critical areas such as manufacturing, healthcare, education, building digital cities, security, medical, transportation, hospitals, room automation etc. Internet of Things enabled devices can even tell when a patient needs a drug in medical care. The benefits of IoT also include cost reduction, efficiency and productivity, business opportunity creation, customer experience, agility and speed. Some excellent examples of IoT devices are smart home security systems, autonomous farming equipment, health monitors, smart factory equipment, wireless inventory trackers, ultra-high speed wireless internet, biometric cyber security scanners, etc. Innovations in IoT and AI (Artificial Intelligence) are constantly working to improve smart home devices. Now is the time to adapt to the advancements in technology, as IoT-enabled devices are ruling the virtual world right now. Innovations in IoT and AI (Artificial Intelligence) are constantly working to improve smart home devices. Now is the perfect time to adapt to the advancement of technology as IoT-enabled devices are ruling the virtual world . There are numerous benefits of using IoT-enabled smart devices in our daily lives.

IoT has all the features that are constantly improving the quality of life of its users. At the same time it simplifies the tasks of the users as well as saves valuable time. One of the key features of IoT is its ability to collect and analyze large amounts of data. This can then be used to optimize processes and make better decisions. IoT devices consist of sensors and mini-computer processors. These sensors and mini-computer processors operate on the data collected by the sensors through machine learning. Machine learning essentially makes IoT devices smarter. The basic elements of IoT are connected devices, central control hardware, data cloud, user interface, network interconnection, system security and data analytics.

IoT essentially combines two emerging technologies. There are wireless connectivity and sensors, are used to interconnect embedded systems. These connected embedded systems are independent micro-controller based computers that use sensors to collect data or information. In IoT systems joint broadcast communication is provided by wireless protocols such as WiFi, Bluetooth, or a custom communication system. Networking protocols are selected based on the distribution of nodes and the amount of data collected.

This information is sent to the main center or computer through the network. Then the main computer processor collects and analyzes the data and stores it in the memory. Even the system takes decisions based on the results of this analysis. Nowadays the Internet is not just a global network for communicating with each other using computers. It is now also a platform to communicate electronically with devices around the world. As a result the world will now become completely saturated with information. As data flows and is shared from one device to another. So now it can be used by many people as well as many devices. In this case keeping these data secure for the good of the economy and society will be one of the primary challenges of the coming era. We have to take several steps to protect this data. Which includes timely firmware updates of IoT devices. Voice detect software should be turned off when not in use.

Encryption method should be used especially in communication. Anti-deeds should be used. Authentication must be deployed between IoT devices so that only trusted devices can communicate. If we can provide maximum security to protect the data in the use of IoT. For this reason IoT will increase productivity as well as create new innovation opportunities for the next generation.
