The health sector is going to experience an era of advancement which will involve the safety and automation of medical devices. Analyzing a patient would be easier and efficient using IoT. It will have a major impact on prevention as well as a treatment of any disease or injury. Additionally, with more automation to human life, it is possible that the physique of humans will drop down and obesity might become a greater problem. With jobs being eaten up by IoT, stress could also come up as another giant problem to the health sector. So IoT has both positive and negative impact on the health sector. But it is quite obvious that humans will cope up with the stress and will move ahead as we have done from our past to adapt in the situation.

There are three important components of the Internet of things (IoT). These are Hardware, software and Conversation Infrastructure.

Raspberry pi is a computer which is as the size of a credit card but is sufficient to perform operations like that of a normal computer. Arduino is an electronic platform and is open-source. It is efficient in taking the input from sensors. Raspberry pi is considered a little higher when compared to Arduino for its superior CPU processing and other factors like that.

Transportation has already been touched by the internet of things. The sector is becoming more connected adding to its advantage. GPS is itself a very helpful factor in vehicles. The speed in the transportation sector will directly imply the speed in human life. The exchange of goods will happen at a faster speed and the safety will be taken into consideration at the same time. Already the concept of driverless vehicles has turned out to be hot

Companies are focused to increase the speed to take the products to the market and to grow their performance. With automation and evolving systems, a company may see a huge high jump in its efficiency. There is a great opportunity for small businesses to jump for exponential growth.

Internet Of Everything is a network or connection set up between humans, things, procedure, and information. Human will tend to stay attached to gadgets and machines such as computers and smartphones. The procedure will turn towards more automation by getting control over the gadgets in no time. Things include sensors, actuators and many more gadgets that could establish a connection to any object.

IoT can improve the performance of the companies with ensuring its security to give higher output. Different business sectors are on the go to gain better profit using IoT implemented to their business as it makes the business more productive by making the process more efficient. The ecosystem of the Internet Of Things is an awesome idea to Revolutionise the working of objects and gadgets around us.

This is a basic yet one of the important IoT Interview Questions you must know about. Go very well known about this answer for the interview.

The title 'Internet Of Things' was coined in the year 1999 by Kevin Sir Frederick. It was initially known by ‘embedded internet' but later came to be known as the Internet of things.

The main characteristic difference between IoT ( Internet Of Things ).and IIoT ( Industrial Internet Of Things ) is their usage. IIoT have a usage in the industrial sector whereas IoT is widely used for consumers.

Benefits of IIoT: It can help industries to be scalable and enhance performance. IIoT is cost-saving and connectivity aids industries to grow substantially and it also contributes to the safety of systems.

With the ability to create a connection and establish a network among daily objects and gadgets, automation comes along the line. Roadways, railways and other transportation mediums connected for the safety and for or increasing the speed. The drainage system, buildings, and other objects to establish a medium for connection to bring speed to human's life. Traffic control could be managed using the technology of IoT by the traffic police department. Buildings equipped which sensors, and where doors and windows are also sensor friendly is a smart city.

WSN: Wireless Sensor Network is a technology that is used under IoT ( Internet Of Things ) System. It was basically started developing for military purposes but are today used widely in industrial and machinery. It need not necessarily be connected to the internet, it has the functions beyond it.

IoT : Internet Of Things is a concept way broader that involves the connectivity between different gadgets and daily objects. IoT helps to make human life easier by bringing automation to the system.

The devices which are connected to each other through IoT are prone to be hacked and hackers could use cloud endpoints for attacking the server. Proper security should be maintained by the professionals behind the security task.

There are three major components of IoT systems :

1)-Sensors Devices

2)-Connectivity

3)-Data Processing

Sensors: Sensors have the crucial task of collecting very tiny data in its range. The data collected may vary from large to small and complex to the simplicity of the data. Devices are capable of inbound more than a single sensor and can have a number of sensors. For example, a smartwatch can sense the temperature, is capable to sense heartbeat and when connected with smart shoes it can count steps and distance the person walked.

Connectivity: After the sensors, I have done the job of collecting data, the next task is to send the collected data to a cloud infrastructure. For this, a medium is required. There are many mediums which can help seniors to connect to the cloud. Sum of many such mediums includes Wi-fi, Cellular networks, Bluetooth and satellite networks. It is very significant to after the best look liberty choice for the system of IoT because of different specifications of every choice.

Data Processing: After the data is on the cloud, now it’s the software that processes the obtained data. It is necessary to process the data so that raw data could be converted into useful and helpful information. This could be done through manipulation of the data that has arrived on the cloud through connectivity networks.

When objects will be capable of communicating with each other, they will help in making our lives simpler and smarter. It will save our time by allowing devices to be automated. Taking an example, when you return home from your office and turn on the switch of your room lights, it will give a signal to your geezer to automatically start heating the water.

Meanwhile, a signal is already sent to your coffee machine to prepare coffee for you and all this will be done automatically with ease, making you feel relaxed. IoT ( Internet of Things ) plays a great role in speeding up our daily routine and hence making the process of advancement to be faster.

IoT is an abbreviated form of 'Internet Of Things'. It is all about the connectivity of day to day gadgets and devices to the internet such that those gadgets and objects can communicate with each other and thereby function together. Also, they can be managed remotely and controlled with ease.
