Do you know : What is IoT?

IoT - Internet of things

The Internet of Things refers to a number of objects connected to the internet and which are efficiently worked and managed by the internet, used for collecting, storing and sharing data over the network. It is the network of physical objects i.e. devices, buildings, vehicles and other items embedded with electronics, software, sensors and network connectivity that can enable these objects to collect and exchange data. A phenomenon which connects a variety of things. It is the intelligent connectivity of physical devices driving massive gains in efficiency, business growth, and quality of life. In simple words, it can be stated as the capability of everyday devices to connect to other devices and people through the existing Internet infrastructure.



The history behind IoT-

Internet-connected devices which are an application of IoT was first introduced in 1982 by a modified Coca-Cola vending machine able to report its inventory and whether newly loaded drinks were cold or not. Somewhere further new evolutions started introducing, many companies started making their own machines which could work on the Internet. This got a new stroke when Bill Joy envisioned device-to-device communication as a part of his "Six Webs" framework. It is said that  Kevin Ashton was the one who coined this term "Internet of Things". The key driving force behind the Internet of things is the MOSFET. The MOSFET is the basic building block of most modern electronics, including computers, smartphones, tablets and Internet services. Advancement in IoT can be seen through MOSFET and further in many new technologies introduced which showed more advancement in IoT.



Some of its characteristics are Interconnectivity: Everything can be connected to global information and communication infrastructure.d communication infrastructure.

Heterogeneity:  Devices within IoT have different hardware and use different networks but they can still interact with other devices through different networks.

Things-Related services:  Provides thing-related services within the constraints of things, such as privacy and semantic consistency between physical and virtual thing.

Dynamic changes: The state of a device can change dynamically.



What are drawbacks of IoT- There are a number of serious concerns about dangers in the growth of IoT, especially in the areas of privacy and security, and consequently industry and governmental moves to begin to address these. Some main drawbacks are - Loss of privacy :              As all the household appliances, industrial machinery, public sector services and may other devices are all connected to the internet, a lot of information is available on it, as a result, this information is prone to hackers and thus which is a severe threat.

Complexity:

IoT is a diverse and complex network. Any failure or bugs in the software or hardware will have serious consequences. Even power failure can cause a lot of inconveniences.



Where can we use IoT - A lightbulb that can be switched on using a smartphone app is an IoT device, as is a motion sensor or a smart thermostat in your office or a connected streetlight. Some larger objects may themselves be filled with many smaller IoT components, such as a jet engine that's now filled with thousands of sensors collecting and transmitting data back to make sure it is operating efficiently. At an even bigger scale, smart cities projects are filling entire regions with sensors to help us understand and control the environment. Some basic applications can be seen in the fields like :

-Worksites -Medical and healthcare -Industrial applications like manufacturing,  scaling etc -Smart controlled vehicles and devices -Household appliances And any other devices which are connected over the internet and can be run through it can be said as an application of IoT.
