Internet of Things(IoT)

 “In God We Trust. All Others Must Bring Data.” W. Edwards Deming, Statistician, Professor, Author

What is IoT:
Internet of Things or IoT , is  a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers ( UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computing interaction.
Let simplify it..
A thing in Internet of Things can be a person or any other natural or man-man project that can be assigned an IP address and is able to transfer data over a network.

What is an IoT device:
It's a physical object that connect to the Internet. It can be a fitness tracker, a lock or a appliance- even a light bulb.
Imagine fitness band which track your heartbeat...and can flag potential health problems.

How will IoT affect me:
The Internet of Things has arrived and it's going to introduce incredible opportunity over the next five years. And while smart things are exactly that, the IoT industry has a long way to go on in terms of overall security.

How IoT works:
A complete IoT system integrates four distinct component :

• Sensors/ Devices
• Connectivity
• Data Processing 
• User Interface

1. Sensors/ Devices:- First sensors or device collect data from environment.

2. Connectivity: Next, the data is send to the cloud, but it needs a way to get there! 

                           The sensors/ devices can be connected to the cloud through a variety of methods                                   including : cellular, satellite, WiFi, Bluetooth, low power wide area networks                                       (LPWAN), connecting directly to the internet via ethernet.

3. Data Processing: Once the data gets to the cloud, software performs some kind of processing on                                      it and then user comes in.

4. User Interface: Next, the information is made useful to the end-user in some way. This could be                                  via an alert to the user (email,text,notification).

                              However, it's not always a one way street. Depending on the IoT application, the                                  user may also be able to perform action and affect the system. And some action                                    may performed automatically.

Benefits of IoT:

The Internet of Things offers a number of benefits to organizations, enabling them to:

• monitor their overall business processes.
• improve the customer experience.
• save time and memory.
• enhance employee productivity.
• integrate and adapt business models.
• make better business decisions.

IoT encourage companies to rethink the ways they approach their business, industries and markets and give them the tools to improve their business strategies.

The Future of IoT:

There are 12 billion devices that are currently connect to the Internet, and researches at IDC estimate that by 2020 there will be 26 time more connected things than people.

According to Garter, consumer applications will drive the number of connected things, while enterprise will account for most of the revenue.
