HOME            UNIT 1               UNIT 2 IoT: A Web 3.0 View EVOLUTION OF THE WEB If it comes to pass, Web 3.0 will be the successor to two previous generations of the web. The first generation, referred to as Web 1.0, was invented in 1989 by Tim Berners-Lee, a British computer scientist who applied the hypertext concepts for linking digital text proposed in 1963 by Ted Nelson , an American information technology pioneer. Besides programming the first browser, Berners-Lee wrote the Hypertext Markup Language ( HTML ), which tells browsers how to display content, as well as the Hypertext Transfer Protocol ( HTTP ) specifying how web servers transfer files to browsers. He also started designing software for a "Semantic Web" that would link data across web pages, but hardware constraints prevented its implementation. The public was not much aware of the web until 1993 with the release of Mosaic, the first popular browser, later renamed Netscape Navigator. According to Harbo

Architecture of IOT

HOME                             UNIT - 1 Architecture of IOT  In simple terms, it is a process that consists of at least 4 stages or layers, which must work along to build the IoT architecture. So, the  architecture IoT  requires connected hardware (that gathers data), a mean of communication to transmit the data to or from a cloud, a system that allows to process all data, and a data center (which can work in the cloud or in a local server) that will allow to store, handle, and analyze the information provided. Types of layers of IoT architecture   Basic layers of IoT architecture The most common layers of Internet of Things architecture are 4, however, it doesn’t mean that every IoT device has the same amount, the minimum to guarantee a stable project is four layers, but depending on the complexity, an  IoT product development company  can decide to add more layers to the project. 1. Sensing layer: This layer of IoT architecture contains all the different devices and sensors that ar
