Internet of Things Study Set- Questions and Correct Answers

What is the Internet of Things (IoT)? also called the Internet of Everything or the Industrial Internet new technology paradigm envisioned as global network of machines and devices capable of interacting with each other IoT essential technologies RFID Wireless sensor networks Middleware Cloud computing - IaaS+SaaS+data storage IoT applications RFID Allows automatic identification and data capture using radio waves, a tag, and a reader. Wireless sensor networks (WSN) -consist of spatially distributed sensor-equipped devices to monitor physical or environmental conditions -can cooperate with RFID systems to better track the status of things such as their location, temperature, and movements Middleware Software layer between software applications to make it easier for software developers to perform communication and input/ output. Hides details of different technologies fundamental to free IoT developers from software services that are not directly relevant to the specific IoT application. Middleware gained popularity in the 1980s due to its major role in simplifying the integration of legacy technologies into new ones. Complex distributed infrastructure of the IoT with numerous heterogeneous devices requires simplifying the development of new applications and services, so the use of middleware is an ideal fit with IoT application development. Cloud computing - IaaS+SaaS+data storage Cloud computing - model for on-demand access to a shared pool of configurable resources (e.g., computers, networks, servers, storage, applications, services, software) Can be provisioned as Infrastructure as a Service (IaaS) or Software as a Service (SaaS). Many IoT applications require massive data storage, huge processing speed to enable real- time decision making, and high-speed broadband networks to stream data, audio, or video.
