What is IoT?
- In the Internet of Things, "things" refers to any sensor or attribute capable of reading or detecting data from various physical quantities that can be quantified using these sensors.
- An entity or physical object with a unique identification, an embedded system, and the ability to transfer data across a network is referred to as a thing in the context of the Internet of Things (IoT).
- The term "things" is commonly used in the IoT to refer to embedded devices that can connect with the internet.
- These embedded devices should be able to collect data from their surroundings, process it, and interact with the internet in order to operate the appropriate appliances based on the specifications.
What is WoT?
- The Web of Things is a modification of the Internet of Things in which smart things are integrated not only into the Internet (network), but also into the Web Architecture (application).(वेब ऑफ थिंग्स इंटरनेट ऑफ थिंग्स का एक संशोधन है जिसमें स्मार्ट चीजों को न केवल इंटरनेट (नेटवर्क) में, बल्कि वेब आर्किटेक्चर (एप्लिकेशन) में भी एकीकृत किया जाता है।)
- The Web of Things (WoT) is a computer concept that show a future in which common things are easily connected to the Internet.
- The "things" must have embedded computer systems that can communicate with the Web in order to participate in WoT.
- These smart gadgets would subsequently be able to connect with one another utilizing ordinary Web protocols.
- The Web of Things is designed to be a connecting element between several IoT protocols.
- In the Web of Things, devices and their services are fully integrated in the Web because they use the same rules, protocols and techniques as traditional Web sites. (वेब ऑफ थिंग्स में, डिवाइस और उनकी सेवाएं पूरी तरह से वेब में एकीकृत हैं क्योंकि वे पारंपरिक वेब साइटों के समान नियमों, प्रोटोकॉल और तकनीकों का उपयोग करते हैं।)
- This means that you can write applications that interact with embedded devices in exactly the same way as you would interact with any other Web service.

| WoT vs IoT |
- The limitations of the IoT become tuff as soon as one wants to integrate devices from various manufacturers into a single application or system.
- To illustrate how the Web of Things can deal with these limitations lets take an example of "KUTHAR" owner of a hotel.
- KUTHAR wants to link all of the equipment in all of his hotels' rooms digitally so that he can monitor, control, and enhance hotel management from the deck of his boat in the Bahamas, using a single Web-based "hotel control center" application.
- At the same time, this technology has the potential to provide each visitor in his hotels with a more pleasant and customized experience.
Common limitations of WoT.
- The WoT design should allow multiple eco-systems to operate together utilizing web technologies.
- The WoT design should be built on RESTful APIs and based on web architecture.
- The WoT architecture should allow for the usage of a variety of payload formats that are routinely used on the internet.
- Different device architectures must be supported by WoT architecture, which should not impose a client-server implementation of system components.
