What is Internet of things (IoT)?

On 12 August, 2019, Reliance Industries (RIL) Chairman and Managing Director (CMD) Mukesh Ambani announced that the Internet of Things (IoT) for Jio platform will be commercially available from 1 January, 2020. Do you know what is Internet of Things (IoT), how IoT will work, what are the pros and cons of IoT? Let us find out!

What is Internet of Things?

Have you ever dreamed that when you wake up in the morning automatically your coffee start brewing, some unseen computing device turn on the TV news, starts reading your schedule and responds to your voice commands etc. Such type of things we have seen in the movie, or in a science fiction Isn't it! But now in reality all this will be possible. The technique that supports above mentioned things is known as Internet of Things (IoT).

What is Internet of Things?

Sometimes it is known as Internet of Everything (IoE). It consists of web-enabled device that will collect or send data and also act on the data that found in the surrounding, environments embedded with sensors, processors and communication hardware. This device is known as “connected “or small devices and is able to talk to other related devices. The process which is necessary for communication is machine-to-machine (M2M). It acts only with that information that they get from one another.

Amazing is that human can give instructions or access the data but the device will do most of the work on their own that is without human intervention.The existence of this technique has been made possible due to the tiny mobile components that are available these days.

The devices that will be connected, generate huge amount of internet traffic like loads of data that can be used to make devices useful. But can also be used for other purposes. No doubt, all this new data and the accessible nature of the internet devices will raise both private and security concerns.

Uses of Internet of Things (IoT) technology

Through this technique you will be able to see real time information that we have never done before. Even through this we can monitor our families and homes by using remote to keep them safe. Businesses can be improved, productivity increases, material waste will be reduced. By placing sensors in the infrastructure of the city will help in reducing the congestion on road and also warn us before the infrastructure in danger. Even the environmental conditions can be improved by the gadgets used openly and also reduce the disasters.

No doubt nowadays these types of gadgets and techniques are emerging everywhere to enhance any physical object.

Internet of Things (IoT): History

Kevin Ashton, co-founder of the Auto-ID Center in 1999 at made a presentation to Procter and Gamble (P&G) and in that he mentioned about Internet of Things and focused to incorporate new technique. In fact the MIT Professor Neil Greshenfeld's in his book namely ‘When things Start to Think’ in 1999 did not used the IoT but provided a clear vision of IoT and its benefits. It is said that IoT is evolved from several technologies that is from wireless technologies, micro electromechanical systems (MEMS), micro services and the internet. It helped in bridging the gap between Operational Technology (OT) and information technology (IT) that will help in generating unstructured machine data and analysed it for further improvements.

Therefore, Ashton was the first person who had mentioned about the internet of things, who have presented an idea of connecting devices which already was there since 1970s under the monikers embedded internet and pervasive computing.

IoT will take machine-to-machine (M2M) to the nest level. IoT is a sensor of network of billions of smart devices that connect people, systems and other applications to collect and share data. With the foundation M2M offers the connectivity that enables IoT.

It is also said that Internet of Things is a natural extension of supervisory control and data acquisition (SCADA) which is a category of software application program for process control, to gather data from remote locations from real time to control equipment and conditions. Let us tell you that SCADA systems include hardware and software components.

Also, we can't forget that the concept of IoT ecosystem does not come on its own until the middle of the 2010 when, in part, the government of China announced to make IoT a strategic priority in its five-year plan.

How IoT works?

IoT ecosystem consists of web-enabled smart devices that use embedded processors, sensors and communication hardware to collect, send and act on data they acquire their environments. IoT devices will share the sensor data that they take by connecting to an IoT gateway or other device where data is either sent to the cloud to be analysed or analysed locally. Sometimes these devices communicate with other devices and act on the information that they get from one another. Human intervention is not required for the processing of the data.

IoT Benefits

Several benefits are offered by the IoT to an organisation.

- Help in monitoring the overall business processes.

- Help in improving the experience of the customer.

- Save time and money.

- Productivity of the employee will increase.

- Adapt and integrate business models.

- Business decisions can be made better by IoT.

- Revenue generation can also be increased.

- IoT encourages companies to rethink the ways they approach their business, industries, markets and can also improve their strategies.

Disadvantage of IoT

- As several informations will be shared by different devices so, the potential of hacker to hack data or to steal confidential information will increase.

- Enterprisers have to deal with millions of IoT devices and so collecting and managing data will be difficult task.

- If there is any virus in the system then all the connected devices will also become corrupted.

- As, there is no international standard of compatibility for IoT, it is difficult for devices from different manufacturers to communicate with each other.

So we can say that Internet of Things (IoT) is the interconnection through the internet of computing devices that are embedded in everyday objects, enabling them to send and receive data. Also, how it is used, what will be the benefits and disadvantage of IoT etc.
