IoT vs WoT Quiz

Internet of Things (IoT) vs Web of Things (WoT)

• IoT is a network of interconnected physical devices
• WoT extends IoT by adding web technologies for better connectivity and interoperability
• WoT uses web protocols (HTTP, WebSocket) for device communication
• WoT aims to boost interoperability by utilizing web standards

Web of Things (WoT) Architecture

• Composed of layers:
  • Layer 1 (Accessibility): Converts anything into a web thing, enabling interaction with HTTP requests
  • Layer 2 (Findability): Makes data more accessible, allowing applications to understand data purpose
  • Layer 3 (Sharing): Securely transfers data between services
  • Layer 4 (Composition): Tools for building applications for web of things
• Based on modular building blocks and levels, supporting various application domains
• Standardized definition and programming for consistent IoT behavior
• Security and privacy features

Need for WoT

• Addresses interoperability problems in IoT
• Enables easier data exchange between IoT platforms and devices
• Supports scalability for managing numerous connected devices
• Offers a user-friendly interface for IoT devices.
• Automates tasks for improved efficiency and user experience

Benefits of WoT

• Enhanced interconnectivity between various IoT platforms and devices
• Improved user experience via intuitive interfaces
• Data insights for better decision-making
• Facilitate innovation and development of new IoT services and apps

Difference Between IoT and WoT

• IoT: Network of interconnected physical devices; often relies on proprietary protocols
• WoT: Extension of IoT; utilizes web technologies for enhanced connectivity and interoperability; built on open, standardized web protocols
• IoT: Data access and control may be limited to specific platforms; WoT: Facilitates data access using standardized web interfaces and APIs
• IoT: Frequently faces scalability challenges; WoT: Aims for scalability via standardized communication
• IoT: Often lacks standardized interfaces; WoT: Emphasizes uniform user experiences across devices via web-based interfaces

Programming Paradigms

• Procedural: Programs as a series of steps (procedures)
• Functional: Based on pure functions that produce outputs without side effects
• Object-Oriented: Organizes data and methods into 'objects' for enhanced code organization, reusability, and maintainability

Object-Oriented Programming (OOP) Concepts

• Class: Blueprint for objects
• Object: Instance of a class
• Data Abstraction: Reveals essential information while hiding internal details
• Encapsulation: Bundles data and methods within an object
• Inheritance: Creating new classes based on existing ones, promoting code reusability
• Polymorphism: Allows objects of different classes to be treated as objects of a common type

What is Arduino?

• Open-source electronics platform with easy-to-use hardware and software
• Can read inputs (sensors, buttons) and convert them into outputs (LEDs, motors)
• Based on Processing programming language
• Supports various projects, from everyday objects to complex scientific instruments

What is Raspberry Pi?

• Small, single-board computer
• Inexpensive, cross-platform compatible
• Used for various applications, including web development, IoT projects, and robotics projects
• Based on an ARM processor
• Includes GPIO ports, HDMI, USB, and other interfaces for connecting external components
