Internet of  Things

IoT (Internet of Things) is an advance automation and analytics system which exploits networking, sensing, big data, and artificial intelligence technology  to  deliver complete systems for a product .
• The things like electronics, automobiles, physical devices which are connected to the network is called IoT.
• Bridge the Gap between Virtual and physical world.
• Advanced and analytics system which exploits networking, sensing, big data, and artificial Intelligence technology to deliver a complete systems for product or service.
• IBM Watson defines that  “It is growing range of Internet connected devices that capture an enormous amount of information everyday”.
• According to McKinsey & company “The IoT  has the potential to fundamentally shift the way we interact with our surroundings".
Advantages:
• Improved Customer Engagement, Technology Optimization, Reduced Waste, Enhanced Data Collection
Disadvantages:
• Security, Privacy, Complexity, Flexibility, Compliance

What Devices Make it to IoT? 

 Physical objects + Controllers, sensors, actuators +Internet  = Internet of things

Physical Objects: Smartphone's range of sensors like and connectivity options have a well equipped to Internet of Things. Device can automatically monitor our movements, location, and workouts throughout.

Controllers, Sensors, Actuators:

• A controller is a device  using electronic techniques in combination, form a microprocessor which monitors physically the operating conditions .
• A sensor is a device that measures a physical quantity and converts it into a 'signal' which can be read by an observer.
• An actuator is a component of a machine that is responsible for moving or controlling a mechanism or system.
Internet:

The internet is the global system of interconnected computer networks that use the internet protocol  (TCP/IP) to link devices worldwide.

Wyliodrin Architecture:

3C'S of IoT: The 3C's of Iot have been divided into 2 types. They  are followed as:
• Industrial Iot
• Commercial Iot

Industrial Iot: The “3 C’s requirement for Industrial IoT systems”.
• Context: Any piece of sensor data needs context, and without it there is limited meaning of an isolated data set. For example, a sensor measuring external weather when combined with a compressed air system performance data in a factory provides context to the overall system performance. This means combining computing infrastructure with data modelling and systems engineering experience is a must to provide context to any IoT data set.
Closing the loop: The Industrial IoT (operational technology) world relies on closed loop systems from controlling processes to scheduling maintenance. A typical industrial systems map, for any medium to large industrial site, is a heterogeneous map comprised of systems from various suppliers that need to work in unison delivering specific process requirements or equipment performance.
• For any IoT system to work within this infrastructure, there is a need for the system to be able to integrate with other OT systems and also enable closing a process or system loop. For example, if the IIoT system is delivering new process KPI’s through additional sensor data, it needs to also deliver a system view to close the loop for the process performance and provide control recommendations to optimise process performance.  
Criticality: Industries are run on 24x7, 365-day cycles requiring a range of critical systems to make the factory shop floor or mining, oil & gas operations work seamlessly. For these operations to allow a new system to be added to their existing infrastructure, it needs to deliver something new that is critical to the process.
• For example: This can be a new insight from the data providing dynamic recommendations to the control system or to the operator before the event occurs, or identifying waste in the process with a way to eliminate it.
• Without criticality of the information delivered by the IIoT system, it would face an uphill battle to be made a part of the Industrial systems map.

Commercial IoT:

 Control : At the bottom of the pyramid, the devices work on their own and isolated. They can go through life on their own and interaction is necessitated directly between the user and the device. Your Toaster is a example of this, it's happy to fully function on it's own never knowing another toasted (or any other device) ever existed.
"These devices are bottom of the ladder and aren't very smart at all."
Connected :The next level is a device that can communicate with other devices. (Unfortunately, at this point often the communication is uni-directional and more in a slave-master type of relationship.)
Your Logitech Harmony remote is a example of this, as it's happy to tell your Blue-Ray Player, Receiver and TV what to do. Once you've gotten used to interacting with the single remote it's hard to imagine interacting with every single device one-at-a-time (like when you have to debug which device is not working properly!?!).
"These devices are smarter as they have to know at some level to communicate to other devices."

Cooperation-Coordination - The 3rd and final level IoT is devices that work together for a common good. At this point the magic happens as suddenly the sum is greater than the parts.
Beyond gains from simplification, new features and powers emerge from the gestalt/collective.
 For example Bit Coins is much more powerful than a simple collection of electronic banking institutions. Your car cooperating with your house so you can seamlessly continue that conference call would be another use-case.
